Entacapone (Comtan®) is a prescription medication used to treat Parkinson's disease. It is always used in combination with carbidopa-levodopa products (Sinemet®, Sinemet® CR, or Parcopa®), as it does not have any activity for treating Parkinson's disease when used without levodopa. Entacapone is useful for people who experience "wearing off" of their carbidopa-levodopa before each dose.
Entacapone is never used without carbidopa-levodopa, since it has no effect on Parkinson's disease without levodopa.
Common side effects of entacapone (when combined with carbidopa-levodopa) include but are not limited to:
- Involuntary movements (dyskinesia)
- Urine discoloration
