Levodopa is the building block the brain turns into dopamine, the chemical messenger that runs low in Parkinson disease. It remains the most effective medicine for the stiffness and slowness of the condition, and is nearly always given with carbidopa or benserazide.

What Levodopa Is Used For

Parkinson disease
Parkinsonism caused by other conditions
Movement difficulty, muscle stiffness and tremor

Common Side Effects

Nausea, especially when starting
Low blood pressure on standing
Vivid dreams or disturbed sleep
Involuntary movements with long term use

Precautions

It should never be stopped abruptly. Vitamin B6 in large amounts and high protein meals can reduce its effect when levodopa is taken alone, so follow the timing your doctor sets. Tell any new doctor that you take it, since several anti sickness and antipsychotic medicines block dopamine and can undo its benefit.
