It is very important that your doctor check your progress at regular visits, especially in the first few months if you have epilepsy. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it.
It is important to tell your doctor if you become pregnant. Your doctor may want you to join the North American Antiepileptic Drug Pregnancy Registry. The registry is used by pregnant patients who are taking this medicine.
This medicine may cause some people to be agitated, irritable, or display other abnormal behaviors, such as feeling sad or hopeless, getting upset easily, or feeling nervous, restless, or hostile. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. If you, your child, or your caregiver notice any of these side effects, tell your doctor right away.
This medicine will add to the effects of alcohol and other CNS depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds; sedatives, tranquilizers, or sleeping medicines; prescription pain medicine or narcotics; other medicines for seizures (eg, barbiturates); muscle relaxants; or anesthetics, including some dental anesthetics. Check with your medical doctor or dentist before taking any of the above while you or your child are using gabapentin.
Gabapentin may cause vision changes, clumsiness, unsteadiness, dizziness, drowsiness, sleepiness, or trouble with thinking. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert, well-coordinated, or able to think or see well. If these side effects are especially bothersome, check with your doctor.
Check with your doctor right away if you or your child have more than one of the following symptoms: fever; rash; swollen, painful, or tender lymph glands in the neck, armpit, or groin; unusual bleeding or bruising; or yellow eyes or skin. These may be symptoms of a serious and life-threatening allergic reaction.
Do not stop using gabapentin without checking with your doctor. Stopping the medicine suddenly may cause seizures. Your doctor may want you or your child to gradually reduce the amount you are taking before stopping it completely.
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.
