pramipexole (Mirapex, Mirapex ER)

Brand Names: Mirapex, Mirapex ER

Generic Name: pramipexole

What is pramipexole (Mirapex, Mirapex ER)?

Pramipexole has some of the same effects as a chemical called dopamine, which occurs naturally in your body. Low levels of dopamine in the brain are associated with Parkinson's disease.

Pramipexole is used to treat symptoms of Parkinson's disease (stiffness, tremors, muscle spasms, and poor muscle control). Pramipexole is also used to treat restless legs syndrome (RLS).

Only immediate-release pramipexole (Mirapex) is approved to treat either Parkinson symptoms or RLS. Extended-release pramipexole (Mirapex ER) is approved only to treat Parkinson symptoms.

Parkinson's and RLS are two separate disorders. Having one of these conditions will not cause you to have the other condition.

Pramipexole may also be used for purposes not listed in this medication guide.
