What GABARAN Tablets are used for
GABARAN contains gabapentin. Gabapentin belongs to a group of medicines used for treating epilepsy (antiepileptic medicines). These drugs are thought to work by controlling brain chemicals, which send signals to nerves so that convulsions do not happen.
Gabapentin also has analgesic effects. It may also be used for treating neuropathic pain (pain caused by damage to nerves).
Your doctor would have prescribed GABARAN tablets for one or more of the following:
- To treat certain types of epilepsy (partial onset seizures) in combination with other antiepileptic medicines, when the condition is not controlled with other anti-epileptic medicines or there are unacceptable side effects.
- To treat neuropathic pain (pain caused by damage to nerves). A variety of conditions can cause neuropathic pain, e.g., shingles, diabetes, trauma.
GABARAN 600 mg and 800 mg tablets will not be used to start your treatment. Your doctor will give you another brand of gabapentin when you begin your treatment. You will be givenGABARANtablets once your daily dose of gabapentin is 1800 mg (one 600 mg tablet three times a day) or more than 1800 mg.
Your doctor may have prescribed GABARAN tablets for another reason. Ask your doctor if you have any questions about why GABARAN tablets have been prescribed for you.
There is no evidence thatGABARAN tablets are addictive.
Gabapentin may make you sleepy or dizzy. This could affect your ability to drive a car or operate machinery.
