carbidopa/levodopa disintegrating tablet - oral, Parcopa
GENERIC NAME: CARBIDOPA/LEVODOPA DISINTEGRATING TABLET - ORAL (KAR-bi-DOE-pa/LEE-voe-DOE-pa)
BRAND NAME(S): Parcopa
USES: Levodopa and carbidopa are used in combination to treat the symptoms of Parkinson's disease or Parkinson-like symptoms (e.g., shakiness, stiffness, difficulty moving). 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.Carbidopa prevents the breakdown of levodopa in the bloodstream so more levodopa can enter the brain. This can reduce some of levodopa's side effects such as nausea and vomiting, and it may also allow your doctor to increase your levodopa dose more quickly to find the best dose for you. This combination may be used alone or with other drugs for Parkinson's disease.
HOW TO USE: Take this medication by mouth with food, usually 3 to 4 times a day or as directed by your doctor. If you have been taking levodopa without any carbidopa and are taking this combination for the first time, wait at least 12 hours after your last levodopa dose before starting this medication. You may want to take your last levodopa dose in the early evening so that you can start your first dose in the morning. Your doctor will usually reduce your levodopa dose when starting this combination to prevent side effects from too much dopamine. Be sure to follow your doctor's instructions closely.This combination comes in different strengths with different amounts of carbidopa and levodopa in each tablet. Be sure you have the correct strength of both drugs. Your doctor may also prescribe carbidopa alone to be taken with this combination.Gently remove the tablet from the bottle with dry hands just before taking a dose. Immediately place the tablet on the tongue. It will dissolve quickly and can be swallowed with your saliva. No water is needed to take this medication.Avoid high-protein diets because they may prevent absorption of this medication. Separate your dose of this medication as many hours as possible from any iron supplements or products containing iron (e.g., multivitamins with minerals) you may take. Iron can reduce the amount of carbidopa and levodopa available to the body.Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. Dosage is based on your medical condition and response to therapy.Some people may experience a decrease in the effectiveness of this medication just 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.
