USES: This combination medication is used to treat symptoms of Parkinson's disease.Parkinson's disease is believed to be due to a lack of an important chemical (dopamine) in the brain. Levodopa is converted into dopamine in the brain, leading to the relief of Parkinson's disease symptoms. Both carbidopa and entacapone are given with levodopa to increase the amount of levodopa that is converted into dopamine.
HOW TO USE: Take this medication by mouth exactly as prescribed.

Consult your doctor or pharmacist for more details.The dosage is based on your medical condition, previous drug therapy, response to therapy, and side effects if they occur.Some patients may experience a "wearing-off" (worsening of symptoms) before the next dose is due.

Parkinson's DiseaseParkinson's disease is a slowly progressive neurological disease characterized by a fixed inexpressive face, a tremor at rest, slowing of voluntary movements, a gait with short accelerating steps, peculiar posture and muscle weakness, caused by degeneration of an area of the brain called the basal ganglia, and by low production of the neurotransmitter dopamine. Most patients are over 50, but at least 10 percent are under 40.
