Gabapentin Actavis – Gabapentin uses, dose and side effects


100 mg, 300 mg and 400 mg hard capsules

What Gabapentin Actavis is and what it is used for

Gabapentin Actavis belongs to a group of medicines used to treat epilepsy and peripheral neuropathic pain (long-term pain caused by nerve damage).

The active substance in Gabapentin Actavis is gabapentin.

Gabapentin Actavis is used to treat:


Various forms of epilepsy (seizures that are initially limited to certain parts of the brain, whether they spread to other parts of the brain or not). Your doctor will prescribe Gabapentin Actavis to help you treat your epilepsy if your current treatment is not effective enough. You should take Gabapentin Actavis as a supplement to your current treatment unless you have been given other instructions. Gabapentin Actavis can also be used as the sole drug to treat adults and children older than 12 years.

Peripheral neuropathic pain:

Prolonged pain caused by nerve damage. A variety of diseases can cause peripheral neuropathic pain (mainly in the arms and/or legs), such as diabetes or shingles. The sensations of pain can be described as burning, stinging, throbbing, pushing, stabbing, sharp, convulsive, grinding, crawling, stinging, numbness, etc.

Gabapentin contained in Gabapentin Actavis may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before you use Gabapentin Actavis

Do not take Gabapentin Actavis:

  • if you are allergic to gabapentin or any of the other ingredients of this medicine (listed in section 6).

Warnings and cautions

Talk to your doctor or pharmacist before taking Gabapentin Actavis

  • if you have kidney problems. Your doctor may then prescribe a different dosing schedule.
  • if you are on hemodialysis (treatment method for renal impairment where waste products are removed), tell your doctor if you get muscle pain or develop muscle weakness.
  • If you get symptoms such as persistent stomach pain, nausea and vomiting, you should contact your doctor immediately, as this may be a symptom of pancreatitis (inflammation of the pancreas).
  • if you have different types of seizures, including absences.
  • If you have diseases of the nervous system, respiratory diseases or if you are older than 65 years, your doctor may prescribe you a different dosage .

Cases of abuse and dependence have been reported for gabapentin since its introduction. Talk to your doctor if you have a history of substance abuse or addiction.

A small number of people treated with epilepsy drugs such as gabapentin have had thoughts of harming themselves or committing suicide. If you get these thoughts at any time, contact your doctor immediately.

Important information about potentially serious reactions
A few patients taking Gabapentin Actavis have an allergic reaction or a potentially serious skin reaction, which can develop into more serious problems if left untreated. You need to know the symptoms you need to be aware of when taking Gabapentin Actavis.

Read the description of these symptoms in section 4 of this leaflet under “Contact your doctor immediately if you get any of the following symptoms after taking this medicine as they may be serious”.

Muscle weakness, soreness, or pain, especially if you also feel unwell or have a high fever, may be due to an abnormal muscle breakdown that can be life-threatening and lead to kidney problems. You may also have discolored urine and altered blood test results (especially elevated blood creatine phosphokinase). Contact your doctor immediately if you experience any of these symptoms.

Other medicines and Gabapentin Actavis

Tell your doctor or pharmacist if you have recently taken or might take any other medicines. In particular, tell your doctor (or pharmacist) if you are taking or have recently taken medicines for seizures, sleep disorders, depression, anxiety, or any other neurological or mental problems.

Drugs that contain opioids such as morphine

If you are taking any medicine that contains opioids (such as morphine), tell your doctor or pharmacist as opioids may increase the effect of Gabapentin Actavis. In addition, a combination of Gabapentin Actavis and opioids may cause symptoms such as drowsiness and/or difficulty breathing.

Antacids for stomach problems

If Gabapentin Actavis is taken together with antacids for an acidic stomach and heartburn (so-called antacids) that contain aluminum and magnesium, absorption of Gabapentin Actavis from the stomach may decrease. Therefore, take Gabapentin Actavis no earlier than 2 hours after antacids.

Gabapentin Actavis is not expected to affect or be affected by other antiepileptic drugs or pills.

Gabapentin Actavis may affect certain laboratory tests. If you need to take a urine sample, tell your doctor or hospital that you are taking Gabapentin Actavis.

Gabapentin Actavis with food

Gabapentin Actavis can be taken with or without food.

Pregnancy, breastfeeding and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.


Gabapentin Actavis should not be taken during pregnancy unless your doctor tells you to. Fertile women should use effective contraception.

There have been no studies that have specifically examined gabapentin in pregnant women, but it has been reported that other antiepileptic drugs have increased the risk of birth defects, especially when several such drugs are used at the same time. Therefore, as far as possible, you should try to take only one epilepsy medicine during pregnancy, and only in consultation with a doctor.

Do not stop using this medicine suddenly as it can lead to breakthrough seizures, which can have serious consequences for you and your child.


Gabapentin, the active ingredient in Gabapentin Actavis, passes into breast milk. As the effect on the baby is unknown, you should not breastfeed while being treated with Gabapentin Actavis.


No effect on fertility has been observed in animal studies.

Driving and using machines

Gabapentin may cause dizziness, drowsiness, and fatigue. You should not drive, use complicated machines or engage in any other potentially hazardous activities until you know if this medicine affects your ability to perform such activities.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased vigilance. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.

Take any remaining capsules, package and package leaflet with you so that the hospital can easily see which medicine you have taken.
