Tolcapone
Summary
Tolcapone is used to treat Parkinson's disease, which is a condition that affects movement. It helps improve symptoms like stiffness, tremors, and movement difficulties by increasing dopamine levels in the brain.
Tolcapone works by inhibiting an enzyme called COMT, which breaks down dopamine in the brain. Dopamine is a chemical that helps control movement. By blocking this enzyme, Tolcapone increases dopamine levels, improving symptoms like stiffness and tremors.
The usual starting dose of Tolcapone for adults is 100 mg taken three times a day. The maximum recommended dose is 200 mg three times a day. It's taken orally, which means by mouth, and should be swallowed whole without crushing or chewing.
Common side effects of Tolcapone include diarrhea, dizziness, and sleep disturbances. Diarrhea is the most frequent, affecting many users. Dizziness can occur, especially when standing up quickly. Sleep disturbances may include trouble sleeping or feeling drowsy.
Tolcapone can cause serious liver damage, so regular liver function tests are necessary. It's not recommended for people with liver disease. Avoid alcohol, which can increase liver damage risk. Always inform your doctor about your medical history and other medications to prevent interactions.
