Ongentys

This medication is used with other medications (levodopa/carbidopa) to treat Parkinson's disease. Opicapone belongs to a class of drugs known as COMT inhibitors. Many people taking levodopa for Parkinson's disease have problems with the effects of levodopa wearing off between scheduled doses, which causes symptoms to return or get worse. Opicapone blocks a certain natural substance (COMT) that breaks down levodopa in the body. This effect helps levodopa to work better and for a longer time.

Take this medication by mouth on an empty stomach as directed by your doctor, usually once daily at bedtime. Do not eat food for 1 hour before and at least 1 hour after taking opicapone. The dosage is based on your medical condition and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Do not suddenly stop taking this medication unless instructed by your doctor. Doing so may cause side effects (such as fever, severe muscle stiffness) or make your Parkinson's symptoms get worse.

Tell your doctor if your condition does not get better or if it gets worse.

Unwanted/uncontrolled movements, constipation, drowsiness, dizziness, or weight loss may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Some people taking this medication along with levodopa/carbidopa have fallen asleep suddenly during their usual daily activities (such as talking, eating, driving). In some cases, sleep occurred without any feelings of drowsiness beforehand. This sleep effect may occur anytime during treatment with opicapone and levodopa/carbidopa even if you have used these medications for a long time. If you experience increased sleepiness or fall asleep during the day, do not drive or do other possibly dangerous activities until you have discussed this effect with your doctor. Your risk of this sleep effect is increased by using alcohol or other medications that can make you drowsy. See also Precautions section.

Tell your doctor right away if you have any serious side effects, including: fast/irregular heartbeat, mental/mood changes (such as agitation, confusion, hallucinations), unusual strong urges (such as increased gambling, uncontrolled spending, binge eating, increased sexual urges).

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
