Patient Education

Levodopa Oral Inhalation


Levodopa inhalation is used along with the combination of levodopa and carbidopa (Duopa, Rytary, Sinemet) to treat ''off'' episodes (times of difficulty moving, walking, and speaking that may happen when other medication(s) wear off) in people with Parkinson's disease (PD; a disorder of the nervous system that causes difficulties with movement, muscle control, and balance). Levodopa inhalation will not work to prevent ''off'' episodes but will help to control symptoms when an ''off'' episode has already begun. Levodopa is in a class of medications called dopamine agonists. Levodopa works by mimicking the action of dopamine, a natural substance in the brain that is lacking in patients with PD.
