Tadalafil can cause a severe allergic reaction. Symptoms can include:
rash
hives
trouble breathing or swallowing
swelling of your lips, throat, or tongue
If you develop these symptoms, call 911 or go to the nearest emergency room.
Don’t take this drug again if you’ve ever had an allergic reaction to it. Taking it again could be fatal (cause death).
Grapefruit interaction warning
Eating grapefruit or drinking grapefruit juice may increase the levels of tadalafil in your blood. This raises your risk for side effects.
Alcohol interaction warning
Don’t drink large amounts of alcohol when taking tadalafil. Both alcohol and tadalafil can dilate (widen) your blood vessels. When used together, they can cause your blood pressure to drop.
Warnings for people with certain health conditions
For people with heart disease: Sexual activity creates a risk for your heart. Using tadalafil may increase that risk. Don’t use tadalafil if you have a heart condition and your doctor has advised against sexual activity.
For people at risk for prolonged erections: Tadalafil may cause priapism. This condition causes a painful, long-lasting erection. It is a medical emergency. Talk with your doctor before using tadalafil if you have a condition that puts you at higher risk for priapism. These conditions include blood cell conditions such as sickle cell anemia, multiple myeloma, or leukemia Peyronie’s disease (a curved or deformed penis).
For people with vision problems: Retinitis pigmentosa is a rare genetic eye disease. Tadalafil hasn’t been studied in people with this condition, and its use isn’t recommended. Tell your doctor if you’ve ever had severe vision loss, including a condition called NAION (non-arteritic anterior ischemic optic neuropathy). If you’ve had NAION and take tadalafil, you may be at increased risk for having NAION again.
For people with kidney disease or on dialysis: Your body may not be able to get rid of tadalafil correctly. This means the drug would stay in your body longer and raise your risk for side effects. Your doctor may start you on a lower dosage, have you take it less often, or not prescribe it at all.
For people with liver problems: Your body may not process tadalafil correctly. This means the drug would stay in your body longer and raise your risk for side effects. Your doctor may start you on a lower dosage, have you take it less often, or not prescribe it at all.
For people with bleeding disorders or peptic ulcers: Tadalafil hasn’t been studied in people with these conditions. Using tadalafil may cause or worsen bleeding or ulcers. If you take tadalafil, your doctor may monitor you more closely.
Warnings for other groups
For pregnant women: Studies of this drug in pregnant animals haven’t shown risk to the fetus. However, there aren’t enough studies done in pregnant women using the drug for PAH to show whether the drug poses a risk to a human fetus.
Talk with your doctor if you’re pregnant or planning to become pregnant. Animal studies don’t always predict the way humans would respond. Therefore, this drug should only be used in pregnancy if clearly needed.
For women who are breastfeeding: It isn’t known if tadalafil passes into breast milk. If it does, it may cause serious effects in a child who is breastfed. Talk with your doctor if you’re taking tadalafil and you want to breastfeed.
For seniors: If you are age 65 years or older, your body may process this drug more slowly. Your doctor may start you on a lower dosage so that tadalafil doesn’t build up too much in your body. High levels of the drug in your body can be dangerous.
For children: Children younger than 18 years old shouldn’t use tadalafil. It’s not known if tadalafil is safe and effective in children.
Tell your doctor or pharmacist if you’re taking these medicines before you start tadalafil:
nitrates for chest pain, such as glyceryl trinitrate (GTN)
riociguat for pulmonary hypertension
Mixing tadalafil with herbal remedies and supplements
There are lots of treatments that claim to be a “herbal Cialis”, but there is no such thing.
A herbal Cialis has never been approved as a treatment for erectile dysfunction. These treatments may also be fake or unsafe.
Some complementary therapies may have ingredients that could affect the way tadalafil works and cause side effects.
There’s not enough information to say whether complementary medicines, herbal remedies and supplements are safe to take with tadalafil. They’re not tested in the same way as pharmacy and prescription medicines. They’re generally not tested for the effect they have on other medicines.
Tadalafil is not often prescribed in pregnancy, but it may be recommended if you have pulmonary hypertension.
Pulmonary hypertension is an extremely serious condition in pregnancy. If you have this condition, it’s important to use reliable contraception (for example a contraceptive implant or a coil) and to talk to your doctor before trying for a baby. You heart condition will need to be assessed so that you can be given information on the risks of pregnancy to your health.
If you become pregnant while taking tadalafil, you will usually be recommended to continue to take it throughout pregnancy. This is because the risks from pulmonary hypertension are potentially life-threatening without treatment.
It’s important to let your doctors know that you are pregnant as early as possible. This is because you will need to be reviewed in a specialist pregnancy and heart clinic throughout your pregnancy. You will be considered a high-risk pregnancy and will have a lot of additional care.
Tadalafil and breastfeeding
If you are breastfeeding and have pulmonary hypertension, tadalafil is not usually prescribed, unless a specialist recommends it.
Tadalafil and fertility
There’s no evidence to suggest that taking tadalafil will reduce fertility in either women or men.
However, speak to a pharmacist or doctor before taking it if you’re trying to get pregnant.
CIALIS contains the active ingredient tadalafil. CIALIS belongs to a group of medicines called phosphodiesterase type 5 inhibitors.
CIALIS is used to treat:
erectile dysfunction, also known as impotence, in men. This is when a man cannot get, or maintain, a hard erect penis suitable for sexual activity. Following sexual stimulation, CIALIS works by helping the blood vessels in your penis to relax, allowing the flow of blood into your penis. The result of this is improved erectile function. CIALIS will only treat erectile dysfunction if you are sexually aroused. You and your partner will need to engage in foreplay, just as you would if you were not taking a medicine for erectile dysfunction.
urinary symptoms associated with a common condition called benign prostatic hyperplasia. This is when the prostate gland gets bigger with age. Symptoms include difficulty in starting to pass urine, a feeling of not completely emptying the bladder and a more frequent need to pass urine even at night. CIALIS improves blood flow to, and relaxes the muscles of, the prostate and bladder which may reduce symptoms of benign prostatic hyperplasia.
Your doctor may have prescribed you CIALIS to treat either, or both of these conditions.
CIALIS contains the active ingredient tadalafil. CIALIS is used to treat erectile dysfunction and urinary symptoms associated with benign prostatic hyperplasia in adult men.
What should I know before I use CIALIS?
Do not use if you have ever had an allergic reaction to CIALIS or any of the ingredients listed at the end of the CMI.
Do not take CIALIS if you are currently taking any nitrates or amyl nitrite.
Talk to your doctor if you have any other medical conditions such as heart problems or take any other medicines.
What if I am taking other medicines?
Some medicines may interfere with CIALIS and affect how it works.
A list of these medicines is in Section
How do I use CIALIS?
Always take CIALIS exactly as your doctor has told you.
Follow all directions given to you by your doctor or pharmacist.
More instructions can be found in Section in the full CMI.
What should I know while using CIALIS?
Things you should do
Remind any doctor, dentist or pharmacist you visit that you are using CIALIS.
If you have emergency treatment for any suspected heart condition tell the emergency medical or ambulance staff that you are taking CIALIS.
Things you should not do
Do not take CIALIS to treat any other complaints.
Do not give your medicine to anyone else, even if they have the same condition as you.
Driving or using machines
Be careful driving or operating machinery until you know how CIALIS affects you.
Drinking alcohol
CIALIS can be taken with or without food or alcohol. However, drinking alcohol may affect your ability to get an erection, so avoid excessive alcohol.
Looking after your medicine
Store below 25°C.
Keep it where young children cannot reach it.
Are there any side effects?
CIALIS may cause chest pain, headache or migraine, flushing, sweating, nausea or vomiting, fatigue, back pain, muscle pain.
Active ingredient: tadalafil
Consumer Medicine Information (CMI)
This leaflet provides important information about using CIALIS. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using CIALIS.
Tadalafil is used to treat men who have erectile dysfunction (also called sexual impotence). Tadalafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly. The penis is one of the areas where this enzyme works.
Erectile dysfunction is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. When a man is sexually stimulated, his body’s normal response is to increase blood flow to his penis to produce an erection. By controlling the enzyme, tadalafil helps to maintain an erection after the penis is stroked by increasing blood flow to the penis. Without physical action to the penis, such as that occurring during sexual intercourse, tadalafil will not work to cause an erection.
Tadalafil is also used to treat men who have signs and symptoms of benign prostatic hyperplasia (BPH). BPH is caused by an enlarged prostate. Men with BPH usually have difficulty urinating, a decreased flow of urination, hesitation at the beginning of urination, and a need to get up at night to urinate. Tadalafil will make these symptoms less severe and reduce the chance that prostate surgery will be needed. This medicine is also used to treat erectile dysfunction and signs and symptoms of BPH.
Tadalafil is also used in both men and women to treat the symptoms of pulmonary arterial hypertension to improve your ability to exercise. This is high blood pressure that occurs in the main artery that carries blood from the right side of the heart (the ventricle) to the lungs. When the smaller blood vessels in the lungs become more resistant to blood flow, the right ventricle must work harder to pump enough blood through the lungs. Tadalafil works on the PDE5 enzyme in the lungs to relax the blood vessels. This will increase the supply of blood to the lungs and reduce the workload of the heart.

Precautions
It is important that you tell all of your doctors that you take tadalafil. If you need emergency medical care for a heart problem, it is important that your doctor knows when you last took tadalafil.
If you will be taking this medicine for pulmonary arterial hypertension, it is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. Blood and urine tests may be needed to check for unwanted effects.
If you take tadalafil for pulmonary arterial hypertension, do not take Cialis® or other PDE5 inhibitors, such as sildenafil (Revatio® or Viagra®) or vardenafil (Levitra®). Cialis® also contains tadalafil. If you take too much tadalafil or take it together with these medicines, the chance for side effects will be higher.
If you experience a prolonged erection for more than 4 hours or a painful erection for more than 6 hours, contact your doctor immediately. This condition may require prompt medical treatment to prevent serious and permanent damage to your penis.
This medicine does not protect you against sexually transmitted diseases (including HIV or AIDS). Use protective measures and ask your doctor if you have any questions about this.
It is important to tell your doctor about any heart problems you have now or may have had in the past. This medicine can cause serious side effects in patients with heart problems.
Do not use this medicine if you are also using riociguat or a nitrate medicine, often used to treat angina (chest pain). Nitrate medicines include nitroglycerin, isosorbide, Imdur®, Nitro-Bid®, Nitrostat®, Nitro-Dur®, Transderm Nitro®, Nitrol® Ointment, and Nitrolingual® Spray. Some illegal (“street”) drugs called “poppers” (such as amyl nitrate, butyl nitrate, or nitrite) also contain nitrates. If you need to use a nitrate medicine, take it at least 48 hours after your last dose of tadalafil.
Do not drink excessive amounts of alcohol (eg, 5 or more glasses of wine or 5 or more shots of whiskey) when taking tadalafil. When taken in excess, alcohol can increase your chances of getting a headache or dizziness, increase your heart rate, or lower your blood pressure.
If you experience sudden loss of vision in one or both eyes, contact your doctor immediately.
Check with your doctor right away if you have a sudden decrease in hearing or loss of hearing, which may be accompanied by dizziness and ringing in the ears.
Do not eat grapefruit or drink grapefruit juice while you are using this medicine. Grapefruit and grapefruit juice may change the amount of this medicine that is absorbed in the body.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
Cialis is approved for the treatment of men who experience difficulty having and maintaining an erection (impotence).
2. How does Cialis work?
Cialis works by enhancing the effects of one of the chemicals the body normally releases into the penis during sexual arousal. This allows an increase of blood flow into the penis. An erection is the result of an increase in blood flow into certain internal areas of the penis.
3. How is Cialis different from the currently approved products for erectile dysfunction (ED)?
Cialis is different from other currently approved products for ED in that it stays in the body longer. However, there were no studies that directly compared the clinical efficacy and safety of Cialis to other products.
4. How do I take Cialis?
Cialis is taken orally before sexual activity, not more than once daily. Cialis may be taken with or without food. In some patients, the dose strength and maximum frequency of use may be adjusted. For more detailed information consult with your health care provider.
5. Are there any side effects with Cialis?
As with any drug product, there may be side effects. The most commonly reported side effects in patients treated with Cialis during the testing of the product were:
headache
indigestion
back pain
muscle pain
flushing
stuffy nose
Patients who get back pain and muscle aches usually get them 12 to 24 hours after taking Cialis and these usually go away by themselves within 48 hours. A small number of patients taking Cialis also reported abnormal vision.
6. What important information should you know about Cialis?
CIALIS can cause your blood pressure to drop suddenly to an unsafe level if it is taken with any nitrate medication. You could get dizzy, faint or have a heart attack or stroke.
Tell your healthcare provider that you take Cialis. If you need emergency medical care for a heart problem, it will be important for your health care provider to know when you last took Cialis.
After taking a single tablet, some of the active ingredient of Cialis remains in your body for more than 2 days. The active ingredient can remain longer if you have problems with your kidneys or liver, or you are taking certain other medications.
Physicians should discuss with patients the potential for CIALIS to augment the blood-pressure-lowering effect of alpha-blockers and antihypertensive medications.
7. What should I talk to my doctor about when considering if Cialis is right for me?
Because sexual activity can increase the work of the heart, your doctors should talk to you about your heart’s general condition and if Cialis is right for you. Patients who have a condition called “left ventricular outlet obstruction” from valvular problems or heart muscle enlargement may get side effects such as fainting or light-headedness. Because patients with recent heart attacks or stroke, heart pains (angina), heart failure, uncontrolled blood pressure or uncontrolled irregular heart beats, severe liver disease, and retinal eye problems were not studied with Cialis, Cialis is not recommended for these patients. There may be rare occurrences of priapism or painful, prolonged erections. This is a serious condition that requires immediate medical attention. Patients should seek prompt medical attention if their erection lasts longer than four hours.
8. Who should not take Cialis?
Cialis should not be used by patients taking nitrates (such as nitroglycerin tablets or patches) because the combination of these with Cialis could significantly lower blood pressure and lead to fainting or even death in some men.
9. Can Cialis be used with other treatments for impotence?
The safety and effectiveness of Cialis when used with other treatments for impotence has not been studied. Combined use could lead to additional lowering of blood pressure, possibly to unsafe levels. Therefore the use of such treatments in combination with Cialis is not recommended.
10. What if I am taking other drugs?
Always discuss with your health care practitioner ALL of the medications you are taking (prescription and over-the-counter) that way, you can receive the best advice for your own situation. Cialis is not recommended for people taking any form of nitroglycerin because the combination may lower blood pressure to an unsafe level.
11. How will Cialis be supplied?
Cialis will be available as oral tablets in 5mg, 10mg and 20mg strengths.
12. Will Cialis be prescription or OTC (over-the-counter)?
Cialis will be available by prescription only.
13. When will Cialis be available to pharmacies?
FDA has no control over when products are available in pharmacies after FDA approval for marketing. The decision of availability is completely up to the company marketing the product. For further information contact your pharmacist or Eli Lilly and Company directly.
14. How can I report a serious side effect with Cialis to FDA?
FDA encourages anyone aware of a serious side effect, including consumers or patients, to make a MedWatch report.
You can report an adverse event either online, by regular mail or by fax, using the contact information at the bottom of this page.
Tadalafil is a prescription-only active ingredient approved by the FDA for erectile dysfunction. It was popularized by the brand name Cialis and is designed to last longer than Sildenafil.
Cialis (tadalafil) relaxes muscles of the blood vessels and increases blood flow to particular areas of the body.
Cialis is used to treat erectile dysfunction (impotence) and symptoms of benign prostatic hypertrophy (enlarged prostate).
Another brand of tadalafil is Adcirca, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women. Do not take Cialis while also taking Adcirca, unless your doctor tells you to.

Important information
Do not take Cialis if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and some recreational drugs such as “poppers”. Taking tadalafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure.
Some medicines can cause unwanted or dangerous effects when used with Cialis. Tell your doctor about all your current medicines, especially riociguat (Adempas).
Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.
Get medical help at once if you have nausea, chest pain, or dizziness during sex.
Stop using Cialis and get emergency medical help if you have sudden vision loss.
Before taking this medicine
You should not take Cialis if you are allergic to tadalafil.
Taking Cialis with certain other medicines can cause a sudden and serious decrease in blood pressure. Do not take this medicine if you also use:
riociguat (to treat pulmonary arterial hypertension); or
a nitrate drug (for chest pain or heart problems) such as nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, or recreational drugs such as amyl nitrate or nitrite “poppers”.
Some tadalafil can remain in your bloodstream for 2 or more days after each dose you take (longer if you have liver or kidney disease). Avoid nitrate use during this time.
To make sure this Cialis is safe for you, tell your doctor if you have ever had:
heart disease or heart rhythm problems;
a heart attack or stroke;
angina (chest pain), high or low blood pressure;
pulmonary hypertension (unless you are taking tadalafil for this);
a condition called pulmonary veno-occlusive disease (narrowing of the veins that carry blood from the lungs to the heart);
liver or kidney disease (or if you are on dialysis);
vision loss, or retinitis pigmentosa (an inherited condition of the eye);
a bleeding disorder;
a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia;
a physical deformity of the penis (such as Peyronie’s disease), or an erection lasting longer than 4 hours;
a stomach ulcer; or
health problems that make sexual activity unsafe.
Sudden vision loss has occurred in a small number of people taking medicines like tadalafil (Viagra or others). Most of these people already had certain eye problems or had high cholesterol, diabetes, coronary artery disease, a history of smoking, or were over 50 years old).

Cialis vs Viagra – What’s the difference between them?
Cialis and Viagra are both PDE5 inhibitors used for the treatment of erectile dysfunction (ED). Both only work when a man is sexually aroused. Cialis lasts for around 36 hours compared with only 4 to 5 hours for Viagra. Food does not affect the activity of Cialis, whereas food may decrease the effectiveness of Viagra. Cialis can be used once daily, at a smaller dosage, and is also effective at treating benign prostatic hyperplasia (BPH). Dosage of Cialis may need to be reduced in men with liver or kidney problems and risk of interactions may be higher than with Viagra.
Cialis and Viagra Comparation
What ingredients are contained in Cialis or Viagra and how do they work?
Cialis is the brand name for tadalafil and Viagra is the brand name for sildenafil. Both belong to a class of medicines known as phosphodiesterase type 5 (PDE5) inhibitors. PDE5 inhibitors work only in the presence of sexual stimulation, as they rely on the natural release of nitric oxide (NO), a chemical only released during sexual arousal. NO in turn activates other substances to relax the smooth muscle inside the penis to allow the inflow of blood and an erection to occur. PDE5 inhibitors enhance the effect of NO.
Which drug was first approved and which one lasts for longer?
On March 27 th, 1998, Viagra became the first oral pill, and the first PDE5 inhibitor, to be approved by the FDA to treat ED. A generic for Viagra was approved in March 2016 and released in December 2017.
Cialis was first approved for ED on November 21st, 2003. It was the third PDE5 inhibitor to come onto the market (after Levitra [vardenafil]). Cialis has an advantage over Viagra and Levitra in that it lasts for a lot longer – 36 hours, compared with 4-5 hours for Viagra and Levitra. A generic for Cialis was approved in May 2018 and released in September 2018.
How quickly do Cialis and Viagra work and does food have any effect
Cialis generally works within 16 to 45 minutes, and its activity is not affected by food. Viagra generally works within 30 minutes, and its effect may be diminished if taken soon after a high fat meal (which may also delay how fast it works). For this reason, Viagra is best taken on an empty stomach.1,2,7
Effectiveness of all PDE5 inhibitors is similar; although reported effectiveness of Viagra, at 84% is slightly higher than that of Cialis at 81%.7 However, more men prefer Cialis because of its longer duration of effect.
What is the usual dosage of Cialis or Viagra?
Cialis can be taken on an as needed basis, or daily.1Generally, daily dosages are smaller than as needed doses. Typically, Cialis is taken as a 10mg starting dose, prior to sexual activity. The effects of Cialis will last around 36 hours. The dosage may be increased to 20mg if 10mg is ineffective or reduced to 5mg if side effects are intolerable.1
When Cialis is taken for daily use, the recommended initial dosage is 2.5mg once daily, or 5mg for people who also have BPH. Timing of the daily dosage does not matter in people using it solely for ED; however, those with BPH are advised to take it at the same time each day. Do not take more than one dose a day but your doctor may consider an increase in dosage from 2.5 to 5mg if ineffective. Side effects of Cialis include headache and indigestion.
Viagra is taken on an as needed basis, at a dose of 50mg, approximately 1 hour before sexual activity (although can be taken from 30 minutes to 4 hours before). The dose may be increased to 100mg if 50mg is ineffective or decreased to 25mg if side effects are intolerable.2 Viagra should only be taken once a day even though the effects wear off after approximately 4-5 hours. The main side effects are headache, flushing and indigestion.2 Rarely, color perception may be altered with Viagra. This side effect does not happen with Cialis.
Cost of Viagra varies depending on tablet strength but is approximately $24 per tablet for the 50mg strength and $35 for the 100mg strength. Cialis costs approximately $8.50 for the 5mg strength and $28 for the 20mg strength, per tablet.
All PDE5 inhibitors are contraindicated with nitrates. The longer duration of action of Cialis means it is at higher risk for drug interactions, and dosages may need reducing in men with kidney or liver disease. Cialis is not recommended in men who have had a heart attack or stroke within the past 6 months, with either uncontrolled high blood pressure or severely low blood pressure, unstable angina, or other conditions that make sexual activity inadvisable.

What is gabapentin?
Gabapentin is a prescription drug. It comes as an oral capsule, an immediate-release oral tablet, an extended-release oral tablet, and an oral solution.
Gabapentin oral capsule is available as the brand-name drug Neurontin. It’s also available as a generic drug. Generic drugs usually cost less than the brand-name version. In some cases, the brand-name drug and the generic version may be available in different forms and strengths.
Gabapentin (Generic Neurontin ) was developed to treat epilepsy, but it is now used to treat various forms of chronic pain. It works by reducing the number of signals sent through the nerves. If the signals are reduced then the pain will be reduced. Research has shown that Gabapentin can help in treating various types of nerve pain.
Why Gabapentin is used
Gabapentin oral capsule is used to treat the following conditions:
Seizures: Gabapentin is used to treat partial (focal) seizures. It’s taken together with other seizure medications in adults and in children 3 years of age and older who have epilepsy.
Postherpetic neuralgia: This is pain from nerve damage caused by shingles, a painful rash that affects adults. Shingles appears after infection with the varicella zoster virus. This virus occurs in people who have had chicken pox.
Gabapentin may be used as part of a combination therapy. This means you may need to take it with other drugs.
How Gabapentin works
gabapentin mechanism of actions
Gabapentin belongs to a class of drugs called anticonvulsants. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.
It’s not fully understood how gabapentin works. For postherpetic neuralgia, it seems to prevent the increase in sensitivity to pain that occurs. For seizures, it may alter the effect of calcium (low levels of calcium may cause seizures).
Gabapentin off-label usages
Some Research Team performed searches to look for clinical trials where gabapentin was used to treat neuropathic pain or fibromyalgia. They found that 5633 participants had been involved in 37 studies of reasonable quality. They tested gabapentin against placebo for four weeks or more. Studies lasting only one or two weeks are unhelpful when pain can last for years.
Neuropathic pain is pain coming from damaged nerves. It differs from pain messages carried along healthy nerves from damaged tissue (a fall, cut, or arthritic knee).
Neuropathic pain is treated by different medicines than pain from damagedtissue. Medicines like paracetamol or ibuprofen are not effective in neuropathic pain, while medicines that are sometimes used to treat depression or epilepsy can be very effective in some people with neuropathic pain.
Our understanding of fibromyalgia (a condition of persistent, widespread pain and tenderness, sleep problems, and fatigue) is poor, but fibromyalgia can respond to the same medicines as neuropathic pain.
Gabapentin is helpful for some people with chronic neuropathic pain or fibromyalgia. Gabapentin comes as a capsule, tablet, or solution. You take it by mouth. Gabapentin is available as the brand-name drugs Neurontin, Gralise, and Horizant. It’s also available as a generic drug.

This is different for different people. In general, Gabapentin will have to be taken for as long as you are requiring pain relief for nerve pain. Do not stop taking your Gabapentin suddenly if you have been taking it for a while. Your body will be used to the Gabapentin and stopping it suddenly may cause withdrawal symptoms. Reducing the dose slowly as advised by your pain specialist or GP will help stop withdrawal symptoms happening. You may wish to reduce the dose every so often, to check nerve pain is still a problem.
How to take Gabapentin ?
The dose of gabapentin required varies from person to person. To avoid side effects we build up to the dose gradually. The tables in this leaflet show you how this can be done. Some patients can put their dose up faster than others. We call this faster way the FAST TRACK (see table 1).
If you find you are getting side effects with the fast track way of putting your dose up, you can switch to the SLOWER METHOD. ( see table 2).ther people will need to put their dose up less quickly over a number of weeks. This is THE SLOWER METHOD .
As with any medication it is important to check how well it works. With gabapentin this can be in a few days but for most patients may take 4-8 weeks to assess the full benefit. If you feel you are getting no benefit from this medication please discuss this with your GP or pain specialist.
Gabapentin other Off-label usages
Gabapentin is one drug that researchers have studied for preventing migraines. It has a high safety profile and few side effects. This makes it a good option for Migraine prevention. Results from some clinical trials have shown a modest benefit from the use of gabapentin for migraine prevention.
However, the American Academy of Neurology (AAN), the organization that provides guidance for the use of drugs to prevent migraines, has stated that there is not enough evidence at this time to support the use of gabapentin for migraine prevention. Healthcare professionals can choose to prescribe gabapentin when other prevention therapies have not worked, however.
Gabapentin has been proven to be effective for people who have hard-to-treat depression or other mood disorders. Neurontin is not your traditional anxiety drug. It’s a drug primarily described to those with bipolar disorder, not anxiety. Bipolar disorder is a complicated mental health problem.
Gabapentin was successful in helping with rapid cycling and mixed bipolar states in people who have not received relief from valproate or carbamazepine. It appeared that Gabapentin helped more with anxiety and agitation than the other two drugs.
It has also been shown that Gabapentin could aid people with certain types of tardive dyskinesia. That’s why anyone that has been prescribed Neurontin should strongly consider taking it, despite the side effects above and questions about its effectiveness. Bipolar disorder is not something that should be left to chance.
The total number of patients treated with NEURONTIN in controlled clinical trials in patients with postherpetic neuralgia was 336, of which 102 (30%) were 65 to 74 years of age, and 168 (50%) were 75 years of age and older. There was a larger treatment effect in patients 75 years of age and older compared with younger patients who received the same dosage. Since gabapentin is almost exclusively eliminated by renal excretion, the larger treatment effect observed in patients ≥ 75 years may be a consequence of increased gabapentin exposure for a given dose that results from an age-related decrease in renal function.
However, other factors cannot be excluded. The types and incidence of adverse reactions were similar across age groups except for peripheral edema and ataxia, which tended to increase in incidence with age.
Clinical studies of NEURONTIN in epilepsy did not include sufficient numbers of subjects aged 65 and over to determine whether they responded differently from younger subjects.
Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and dose should be adjusted based on creatinine clearance values in these patients.
