Treats Parkinson's disease.

Stalevo (carbidopa / levodopa / entacapone) is a good choice for Parkinson's disease, especially when carbidopa/levodopa starts losing its effect.

Treats advanced stages of Parkinson's disease.

Duopa (carbidopa / levodopa) pumps carbidopa/levodopa into your body throughout the day. It is reserved for advanced Parkinson's disease when your symptoms become more frequent than the dosing of your tablets.
