Entacapone is used together with other medicines to treat Parkinson's disease. Parkinson's disease is a disorder that affects movement of a person, causing symptoms such as tremors, muscle stiffness, slowed movement and impaired balance or walking. It is used to improve the medicinal effect of another Parkinson's disease medicine called levodopa.
Entacapone cannot cure Parkinson's disease, but it can improve the quality of life for people who have the disease.
Take Entacapone exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.
Take Entacapone together with each dose of levodopa.
You may take Entacapone with or without food. Try to take it at the same time each day.
Entacapone must be taken regularly for it to be effective. Continue taking Entacapone even when you feel better. Do not stop taking it unless instructed otherwise, as stopping it suddenly could worsen your condition.
