What happens if I miss a dose (Fanapt)?

What happens if I overdose (Fanapt)?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Overdose symptoms may include drowsiness, fast heart rate, and feeling light-headed.

What should I avoid while taking iloperidone (Fanapt)?

While you are taking iloperidone, you may be more sensitive to temperature extremes such as very hot or cold conditions. Avoid getting too cold, or becoming overheated or dehydrated. Drink plenty of fluids, especially in hot weather and during exercise. It is easier to become dangerously overheated and dehydrated while you are taking iloperidone.

Iloperidone may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.

Drinking alcohol can increase certain side effects of iloperidone.

Before using iloperidone, tell your doctor if you regularly use other medicines that make you sleepy (such as cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by iloperidone.

Tell your doctor about all other medicines you use, especially:
