This medication is used when needed to treat the return of Parkinson's symptoms (known as OFF episodes) in people with Parkinson's disease who are treated with carbidopa/levodopa medicines. Parkinson's disease tends to worsen over time, and you may need extra levodopa from time to time... Parkinson's disease is thought to be caused by too little of a naturally occurring substance (dopamine) in the brain. Levodopa changes into dopamine in the brain, helping to control movement.
