Mirapex

Generic name: Pramipexole
Drug class: Dopaminergic antiparkinsonism agents

Usage of Mirapex

Mirapex 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.

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

Immediate-release tablet (Mirapex) is approved to treat either Parkinson symptoms or RLS. The extended-release tablet (Mirapex ER) is only approved 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.
