Precautions
Drug information provided by: Merative, Micromedex®
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.
This medicine may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. Also tell your doctor if you or your child have sudden or strong feelings, such as feeling nervous, angry, restless, violent, or scared. If you, your child, or your caregiver notice any of these side effects, tell your doctor right away.
This medicine may cause some people to become dizzy, drowsy, clumsy, faint, unsteady, or less alert than they are normally. It may also cause trouble with controlling body movements, which may lead to falls, fractures, or other injuries. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.
Check with your doctor right away if you have a fever, chills, cough, sore throat, swollen, painful, or tender lymph glands in the neck, armpit, or groin, or yellow skin or eyes while using this medicine. These could be symptoms of a serious condition, called drug reaction with eosinophilia and systemic symptoms (DRESS).
This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.
Do not stop taking this medicine without checking first with your doctor. Stopping the medicine suddenly may cause your seizures to return or to occur more often. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely.
Birth control pills containing levonorgestrel may not work as well while you are using this medicine. Use another form of birth control together with your pills during treatment and for at least 1 month after the last dose to avoid getting pregnant. Talk to your doctor if you have questions.
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, medicines for hay fever, allergies or colds, sedatives, tranquilizers, or sleeping medicines, prescription pain medicines or narcotics, and other medicines for seizures. Check with your doctor before taking any of these medicines together with perampanel.
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 (eg, St. John's wort) or vitamin supplements.
