Generic name: pramipexole dihydrochloride

What is Mirapex?

Mirapex is a prescription medicine used to treat:

  • signs and symptoms of Parkinson's disease (PD)
  • moderate to severe primary Restless Legs Syndrome (RLS)

It is not known if Mirapex is safe and effective in children.

What should I tell my healthcare provider before taking Mirapex?

Before taking Mirapex, tell your doctor if you:

  • feel sleepy during the day from a sleep problem other than Restless Legs Syndrome
  • have low blood pressure, or if you feel dizzy or faint, especially when getting up from sitting or lying down
  • have trouble controlling your muscles (dyskinesia)
  • have kidney problems
  • drink alcohol. Alcohol can increase the chance that Mirapex will make you feel sleepy or fall asleep when you should be awake.
  • have any other medical conditions
  • are pregnant or plan to become pregnant. It is not known if Mirapex will harm your unborn baby.
  • are breastfeeding or plan to breastfeed. It is not known if Mirapex passes into your breast milk. You and your doctor should decide if you will take Mirapex or breastfeed. You should not do both.

Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.

The combination of Mirapex and other medicines may affect each other and may cause side effects. Mirapex may affect the way other medicines work, and other medicines may affect how Mirapex works.

Especially tell your doctor if you take:

  • medicines called neuroleptics (phenothiazines, butyrophenones, thioxanthenes) or metoclopramide. Mirapex may not work as well if you take these medicines.
  • extended-release pramipexole (Mirapex ER). Pramipexole is the active ingredient in both Mirapex and Mirapex ER. If you are taking Mirapex ER, you should not take Mirapex.
  • any other medicines that make you sleepy or may increase the effects of Mirapex, such as cimetidine (Tagamet).

Ask your doctor for a list of these medicines if you are not sure.

Know the medicines you take. Keep a list of them and show it to your doctor and pharmacist when you get a new medicine.

How should I take Mirapex?

  • Take Mirapex exactly as your doctor tells you to take it.
  • Your doctor will tell you how much Mirapex to take and when to take it. Do not take more or less Mirapex than your doctor tells you to.
  • Your doctor may change your dose if needed.
  • Mirapex can be taken with or without food. Taking Mirapex tablets with food may lower your chances of getting nausea.
  • If you take more Mirapex than your doctor recommends, call your doctor or go to the nearest hospital emergency room right away.
  • If you miss a dose, do not double your next dose. Skip the dose you missed and take your next regular dose.
  • If you have Parkinson’s disease and your doctor tells you to stop taking Mirapex, you should stop Mirapex slowly as directed by your doctor. If you stop Mirapex too quickly you may have withdrawal symptoms such as:
    • fever
    • confusion
    • severe muscle stiffness

      Do not stop taking Mirapex without talking to your doctor.

What should I avoid while taking Mirapex?

  • Do not drink alcohol while taking Mirapex. It can increase your chance of having serious side effects. See “What are the possible side effects of Mirapex?
