The most appropriate dose of perampanel is one that provides good control of seizures without causing side effects that are too severe.
The recommended starting dose for adults and adolescents who are taking certain anti-epileptic medications, including phenytoin, carbamazepine, or oxcarbamazepine, is 4 mg taken once daily at bedtime. For people who are not taking these medications, the starting dose is 2 mg taken once daily at bedtime. The dose of perampanel can be gradually increased to a maximum dose of 12 mg per day until satisfactory seizure control is seen or side effects become intolerable.
Perampanel tablets may be taken with food or on an empty stomach. Perampanel suspension should be taken without food for the first 2 weeks when you start taking the suspension or if you have switched from tablets to the suspension.
If you are using perampanel suspension, shake the medication bottle for at least 5 seconds before measuring the dose of medication. An oral syringe should be used to measure each dose of the liquid, as it provides a more accurate measurement than household teaspoons.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
It is important that this medication be taken exactly as prescribed by your doctor.
If you miss a dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice. Contact your doctor if you miss more than one day of medication.
Store this medication at room temperature, protect it from light and moisture, and keep it out of the reach of children. The suspension should be used within 90 days after opening the bottle.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
Do not take this medication if you are allergic to perampanel or any ingredients of the medication.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Aggressive behaviour: People taking perampanel may experience feelings of anger, irritability, agitation (restless, anxious, aggressive, emotional, and feeling not like themselves), or they may experience new or worse aggressive behavior. If you experience these side effects or notice them in a family member who is taking this medication, contact your doctor immediately. You should be closely monitored by your doctor for emotional and behaviour changes while taking this medication. Drinking alcohol while taking perampanel may increase the risk for behaviour changes.
Birth control: Perampanel may cause a decrease in the effectiveness of certain hormonal birth control medications. An additional, non-hormonal method of birth control, such as using condoms is recommended for women taking perampanel.
Drowsiness/reduced alertness: Perampanel may affect the mental or physical abilities needed to drive or operate machinery. Avoid driving, operating machinery, or performing other hazardous tasks until you have determined how this medication affects you.
Galactose intolerance: Perampanel tablets are prepared with lactose. If you have lactose or galactose intolerance you should not take the tablet form of this medication.
Hypersensitivity syndrome: A severe hypersensitivity syndrome has occurred for some people with the use of perampanel. This reaction involves a number of organs in the body and may be fatal if not treated quickly. Stop taking the medication and get immediate medical attention if you have symptoms of a severe allergic reaction, including fever, swollen glands, yellowing of the skin or eyes, or flu-like symptoms with skin rash or blistering.
Kidney function: If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.
Stopping the medication: This medication is effective for seizure control only as long as it is being taken regularly. Stopping perampanel may result in seizures occurring more often. If this medication needs to be stopped, it should be done gradually, under the supervision of your doctor. If you believe you need to stop taking perampanel, discuss your concerns with your doctor.
Suicidal thoughts and behaviour: Some people taking anti-seizure medications may have suicidal thoughts or behaviour. If this happens to you or you notice this in a family member who is taking this medication, contact your doctor immediately. You should be closely monitored by your doctor for emotional and behavioural changes while taking this medication.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if perampanel passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication in children under 12 years of age have not been established for children.
