What is the most important information I should know about paliperidone (Invega)?

Paliperidone is not for use in psychotic conditions related to dementia. Paliperidone may cause heart failure, sudden death, or pneumonia in older adults with dementia-related conditions.

While you are taking paliperidone, 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 paliperidone.

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

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

Drinking alcohol can increase certain side effects of paliperidone.

Stop taking paliperidone and call your doctor at once if you have very stiff (rigid) muscles, high fever, sweating, confusion, fast or uneven heartbeats, tremors, restless muscle movements in your face or neck, tremor (uncontrolled shaking), trouble swallowing, or feeling like you might pass out.
