Fycompa is taken orally, either as a tablet or a liquid suspension, once daily at bedtime. Taking it at bedtime helps to manage potential side effects like dizziness and sleepiness.

• Tablets: Swallow tablets whole. Do not crush, chew, split, or dissolve them.
• Liquid Suspension: Shake the bottle well before each use. Use the dosing syringe provided with the medication to measure your dose accurately. Do not use household spoons.
• With or Without Food: You can take Fycompa with or without food.
• Missed Dose: If you miss a dose, do not double the next dose. Take your regular dose at bedtime the next day.
• Gradual Dosing: Your doctor will usually start you on a low dose (e.g., 2 mg once daily) and slowly increase it over several weeks (e.g., by 2 mg increments weekly or every two weeks) until the right dose for you is found. This helps your body adjust and reduces side effects.
• Long-term Treatment: Fycompa is usually a long-term treatment. Do not stop taking it suddenly without consulting your doctor, as this can increase seizures.

Fycompa works differently from many other antiepileptic drugs. Its precise mechanism is unique among AEDs, but it’s understood to affect the way brain cells communicate. Epilepsy involves excessive electrical activity in the brain, often linked to an overactivity of a chemical messenger called glutamate. Glutamate is the main “excitatory” neurotransmitter, meaning it encourages brain cells to become active. Fycompa acts as a selective, non-competitive antagonist of the AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptor. This means Fycompa binds to a specific spot on the AMPA receptor (not where glutamate usually binds) and reduces the effect of glutamate. By dampening this excitatory signaling, Fycompa helps to reduce the overstimulation in the brain that leads to seizures, thus preventing or lessening their occurrence.

• Fycompa affects brain cell communication.
• It reduces the overactivity of glutamate, an excitatory brain chemical.
• It specifically blocks AMPA receptors in the brain.
• By blocking these receptors, it decreases excessive electrical signals.
• This action helps to prevent or reduce seizures.

Fycompa can cause side effects, and patients are monitored closely for them. Common side effects include:

• Dizziness, sleepiness (somnolence), tiredness (fatigue). These are often most noticeable when starting the medication or increasing the dose.
• Irritability, aggressive behavior, hostility, anger. These are serious and potentially concerning side effects that can be dose-related and require immediate reporting to your doctor.
• Problems with balance or walking (gait disturbance, ataxia).
• Nausea, vomiting, abdominal pain.
• Weight gain.
• Headache.
• Anxiety.
• Falls: Increased risk of falls, especially in elderly patients.

More serious, but less common, side effects include:

• Serious psychiatric and behavioral problems: Including suicidal thoughts or actions, depression, agitation, confusion, or believing things that are not true (psychosis).
• Serious allergic reactions (DRESS syndrome): This can involve skin rash, fever, swollen glands, swelling of the face, shortness of breath, yellowing of skin/eyes, or dark urine, and can be life-threatening.

Report any new or worsening symptoms to your healthcare team immediately.

Due to its potential side effects, several important warnings and precautions are associated with Fycompa:

• Serious Psychiatric and Behavioral Problems: Fycompa carries a Boxed Warning about serious psychiatric and behavioral reactions, including aggression, hostility, anger, and homicidal thoughts/behavior. Patients, caregivers, and families must monitor for these changes and report them immediately.
• Suicidal Thoughts or Actions: Like all AEDs, Fycompa can increase the risk of suicidal thoughts or behavior. Monitor for new or worsening depression, agitation, or suicidal ideation.
• Dizziness, Sleepiness, Falls: These are common. Patients should avoid driving or operating heavy machinery until they know how the medication affects them. The risk of falls is increased, especially in the elderly.
• Alcohol: Avoid alcohol completely, as it can worsen behavioral and neurologic side effects.
• Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): This is a rare but life-threatening allergic reaction. Seek immediate medical attention if you develop a rash, fever, or swollen glands.
• Withdrawal: Do not stop Fycompa suddenly, as this can lead to increased seizure frequency and severity.
• Pregnancy and Breastfeeding: Discuss with your doctor. It is not known if Fycompa can harm an unborn baby. Women should use effective contraception during treatment and for a period after. Breastfeeding is generally not recommended.
• Liver or Kidney Problems: Dosage adjustments may be needed for patients with liver or severe kidney impairment.

Fycompa can interact with several other medications, which can affect its effectiveness or increase side effects. It’s crucial to inform your doctor about all prescription drugs, over-the-counter medicines, herbal products, and supplements you are taking. Some important interactions include:

• Other Antiepileptic Drugs (AEDs): Some AEDs like carbamazepine, phenytoin, and oxcarbazepine can speed up the removal of Fycompa from the body, making it less effective. Your doctor may need to adjust your Fycompa dose if you take these.
• Medicines that cause sleepiness or dizziness: Combining Fycompa with other drugs that cause drowsiness (e.g., sleeping pills, anxiety medications, certain pain medicines) can worsen these side effects.
• Alcohol: Drinking alcohol while on Fycompa can significantly worsen side effects like dizziness, sleepiness, and mood changes, including anger and confusion. It should be avoided.
• Hormonal Contraceptives: While less significant than some other AEDs, there might be a theoretical interaction, so discuss your birth control with your doctor.
• St. John’s Wort: This herbal supplement can decrease Fycompa levels and reduce its effectiveness.

Always provide a complete and up-to-date list of all your medications to your healthcare team.

The dosage of Fycompa is highly individualized and determined by your doctor based on your specific seizure type, your response to treatment, tolerability, and any other medications you are taking.

• Starting Dose (Adults & Adolescents 12+): Usually begins at 2 mg once daily at bedtime.
• Titration: The dose is slowly increased by increments of 2 mg, typically no more frequently than weekly intervals, based on how well you respond and tolerate the medication.
• Maintenance Dose (Adults & Adolescents 12+): Commonly ranges from 4 mg to 8 mg once daily, with a maximum recommended dose of 12 mg once daily if needed for seizure control and tolerated.
• Children (4-11 years): Dosing starts lower (e.g., 1 mg once daily for those under 20 kg) and is adjusted based on weight, clinical response, and tolerability, up to a maximum of 6 mg or 8 mg depending on weight.
• With Enzyme-Inducing AEDs: If you are taking other AEDs that speed up Fycompa’s breakdown, your doctor might start you on a higher dose (e.g., 4 mg once daily) and increase it more rapidly.

Always take Fycompa exactly as prescribed by your doctor.

Fycompa is a prescription-only medication (POM). It is not available over-the-counter. Due to its potent effects on the brain, the need for careful dose titration, potential for serious side effects (especially psychiatric and behavioral changes), and its classification as a controlled substance in some regions (due to potential for abuse), Fycompa must be prescribed by a licensed medical doctor, typically a neurologist or an epilepsy specialist. Your doctor will conduct a thorough medical evaluation, including your seizure history, other medications, and psychiatric history, before prescribing Fycompa. Ongoing medical supervision, regular follow-up appointments, and monitoring for side effects are crucial throughout the course of treatment.
