Usage Information
This medication is used to treat the symptoms of Parkinson's disease (such as shakiness, stiffness, difficulty moving) or Parkinson-like conditions. 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. Carbidopa can also reduce some of levodopa's side effects such as nausea and vomiting.
