Treats Parkinson's disease.

Good for treating tremors caused by Parkinson's and for treating uncontrolled movements in people taking antipsychotics.

Helps with movement problems.

Mirapex (pramipexole) is effective for Parkinson's disease or restless legs syndrome, but can cause extreme drowsiness that affects daily living.

Upsides
  • Cogentin (benztropine) can be used with other medicines for people with more advanced Parkinson's who continue to have tremors.
  • Works by itself in people under 65 who only have Parkinson's tremors and not other symptoms.
  • Can be used in people who have movement problems because they're taking antipsychotic drugs.
  • Available as generic.
  • Mirapex (pramipexole) may be better for older people with Parkinson's since it causes fewer movement and mental changes than its alternatives.
  • Mirapex (pramipexole) comes in extended-release form to help reduce side effects and ease administration.
  • Available as a generic so it will be cheaper than similar brand medications.
Downsides
  • Only treats the tremors in Parkinson's and not the other symptoms.
  • Not recommended in people over 65 or those with memory difficulties or problems thinking clearly because they're more likely to have confusion with Cogentin (benztropine).
  • Can't be used in people who have glaucoma.
  • Mirapex (pramipexole) can be used by itself, but is usually used in combination with other medications to treat Parkinson's.
  • Not the best choice if you have kidney problems.
  • You cannot suddenly stop taking Mirapex (pramipexole) if you have been taking it for a long time.
