Opicapone — Uses, Dosage, Side Effects & Safety

Drug class: Neurology

Overview

Opicapone is a prescription medication used in combination with levodopa/carbidopa to treat adults with Parkinson’s disease who experience 'off' episodes—periods when symptoms such as tremor, stiffness, and slowness return between doses of their regular medication. It works by blocking an enzyme called catechol-O-methyltransferase (COMT), which breaks down levodopa in the body. By inhibiting this enzyme, opicapone helps increase and prolong the effect of levodopa, leading to more consistent symptom control. Key points for patients: Opicapone is not used alone; it is always added to existing levodopa/carbidopa therapy. It is usually taken once daily at bedtime. Patients should be aware of possible side effects, including involuntary movements (dyskinesia), and should report any unusual symptoms to their healthcare provider.

Frequently Asked Questions about Opicapone

What is opicapone used for?

Opicapone is used as an add-on treatment to levodopa/carbidopa in adults with Parkinson’s disease who experience 'off' episodes, which are periods when symptoms return between doses of their regular medication.

How does opicapone work?

Opicapone blocks the COMT enzyme, which breaks down levodopa. This increases and prolongs the effect of levodopa, helping to reduce 'off' time and improve symptom control in Parkinson’s disease.

What are the most common side effects of opicapone?

The most common side effects are involuntary movements (dyskinesia), constipation, dry mouth, low blood pressure, and trouble sleeping.

Can I take opicapone with food?

No, opicapone should be taken on an empty stomach, at least 1 hour before or after meals, to ensure proper absorption.

Is opicapone safe for children?

Opicapone is not recommended for use in children or adolescents under 18 years, as safety and efficacy have not been established.

What should I do if I miss a dose?

If you miss a dose, skip it and take your next dose at the usual time. Do not double up doses.

Are there any serious risks with opicapone?

Serious risks include severe allergic reactions, worsening of involuntary movements, hallucinations, and rare but serious conditions like neuroleptic malignant syndrome. Seek immediate medical attention if you experience severe symptoms.
