Gabapentin Teva belongs to a group of medicines used to treat epilepsy and peripheral neuropathic pain (long lasting pain caused by damage to the nerves).
The active substance in Gabapentin Teva is gabapentin which belongs to a class of medicines called Gabapentinoids.
Gabapentin Teva are used to treat:
Various forms of epilepsy (seizures that are initially limited
to certain parts of the brain, whether the seizure spreads to other parts of the brain or not). The doctor treating you or your child 6 years of age and older will prescribe Gabapentin Teva to help treat epilepsy when the current treatment is not fully controlling the condition. You or your child 6 years of age and older should take Gabapentin Teva in addition to the current treatment unless told otherwise. Gabapentin Teva can also be used on its own to treat adults and children over 12 years of age.
Peripheral neuropathic pain (long lasting pain caused by
damage to the nerves). A variety of different diseases can cause peripheral neuropathic pain (primarily occurring in the legs and/or arms), such as diabetes or shingles. Pain sensations may be described as hot, burning, throbbing, shooting, stabbing, sharp, cramping, aching, tingling, numbness, pins and needles etc.
This medicine has been prescribed to you and should not be given to anyone else.
Gabapentinoids can cause dependence, tolerance and addiction, and you may get withdrawal symptoms if you stop taking it or reduce the dose suddenly. Your doctor should have explained how long you will be taking it for and, when it is appropriate to stop, how to do this safely. When your treatment is stopped, it is usually done gradually over a period which is specific to you and may occur over a period of weeks to months. If this medicine is being used for the treatment of epilepsy you must continue to take it as prescribed by your doctor.

Gabapentinoids should only be used by those they are prescribed for. Do not give your medicine to anyone else. Taking higher doses or more frequent doses of gabapentinoids, may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death.
A small number of people being treated with anti-epileptics such as Gabapentin Teva have had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.
Important information about potentially serious reactions
Serious skin rashes including Stevens-Johnson syndrome, toxic epidermal necrolysis and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in association with Gabapentin. Stop using Gabapentin Teva and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.
Read the description of these symptoms in section 4 of this leaflet under ‘Contact your doctor immediately if you experience any of the following symptoms after taking this medicine as they can be serious’.
Muscle weakness, tenderness or pain and particularly, if at the same time, you feel unwell or have a high temperature it may be caused by an abnormal muscle breakdown which can be life-threatening and lead to kidney problems. You may also experience discoloration of your urine, and a change in blood test results (notably blood creatine phosphokinase increased). If you experience any of these signs or symptoms, please contact your doctor immediately.
Other medicines and Gabapentin Teva
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. In particular, tell your doctor (or pharmacist) if you are taking or have been recently taking any medicines for convulsions, sleeping disorders, depression, anxiety, or any other neurological or psychiatric problems.
Medicines containing opioids such as morphine
If you are taking any medicines containing opioids (such as morphine), please tell your doctor or pharmacist as opioids may increase the effect of Gabapentin Teva Hard Capsules. In addition, combination of Gabapentin Teva with opioids may cause sleepiness, sedation, decrease in breathing, or death.
Antacids for indigestion
If Gabapentin Teva and antacids containing aluminium and magnesium are taken at the same time, absorption of Gabapentin Teva from the stomach may be reduced. It is therefore recommended that Gabapentin Teva is taken at the earliest two hours after taking an antacid.
Gabapentin Teva:
- is not expected to interact with other antiepileptic drugs or the oral contraceptive pill
- may interfere with some laboratory tests, if you require a urine test tell your doctor or hospital what you are taking.

Pregnancy
Gabapentin Teva can be used during the first trimester of pregnancy if needed.
If you plan to become pregnant or if you are pregnant or think you may be pregnant, talk to your doctor straight away. If you have become pregnant and you have epilepsy, it is important that you do not stop taking your medicine without first consulting your doctor, as this may worsen your illness. Worsening of your epilepsy may put you and your unborn child at risk.
In a study reviewing data from women in Nordic countries who took gabapentin in the first 3 months of pregnancy, there was no increased risk of birth defects or problems with the development of brain function (neurodevelopment disorders). However, babies of women who took gabapentin during pregnancy had an increased risk of low birth weight and preterm birth.
Contact your doctor immediately if you become pregnant, think you might be pregnant or are planning to become pregnant while taking Gabapentin Teva. Do not suddenly discontinue taking this medicine as this may lead to a breakthrough seizure, which could have serious consequences for you and your baby.
If used during pregnancy, Gabapentin Teva may lead to withdrawal symptoms in newborn infants. This risk might be increased when Gabapentin Teva are taken together with opioid analgesics (drugs for treatment of severe pain).
Breast-feeding
Gabapentin, the active substance of Gabapentin Teva Hard Capsules, is passed on through human milk. Because the effect on the baby is unknown, it is not recommended to breast-feed while using Gabapentin Teva.
