Compare Mirapex vs. Rytary

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Pramipexole (Mirapex, Mirapex ER) and Rytary (carbidopa/levodopa) are both used to treat Parkinson's disease (PD), but they work differently and have different dosing schedules. Pramipexole is a dopamine agonist that helps improve movement problems by raising dopamine levels in the brain. It comes in immediate-release tablets taken three times a day and extended-release tablets taken once daily. Rytary, on the other hand, is a combination of two medications: carbidopa and levodopa. Levodopa is a dopamine replacement, and carbidopa helps prevent levodopa from breaking down before it reaches the brain. These actions helps increase dopamine levels. Rytary is an extended-release capsule taken three times a day. Pramipexole is available in a lower-cost generic version, while Rytary is not, making it potentially more expensive. Both medications can cause sleepiness and sudden sleep episodes, but Rytary also has a risk of heart problems and stomach bleeding. Pramipexole can cause compulsive behaviors like binge eating and gambling.
