What is Stalevo 50 (carbidopa, entacapone, and levodopa)?
Levodopa is converted to a chemical called dopamine (DOE pa meen) in the brain. Symptoms of Parkinson's disease may be caused by low levels of dopamine in the brain. Carbidopa helps prevent the breakdown of levodopa before it can reach the brain and take effect. Entacapone increases levels of levodopa in the body.
The combination of carbidopa, entacapone, and levodopa is used to treat Parkinson symptoms such as muscle stiffness, tremors, spasms, and poor muscle control.
Carbidopa, entacapone, and levodopa may also be used for purposes not listed in this medication guide.
How should I take Stalevo 50 (carbidopa, entacapone, and levodopa)?

Drink plenty of liquids while you are taking this medication.
It may take up to several weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve after a few weeks of treatment. Also tell your doctor if the effects of this medication seem to wear off quickly in between doses.
