Physicians prescribe Mirapex (pramipexole dihydrochloride) for Parkinson's disease and restless leg syndrome (RLS). Researchers aren't sure how it works, but Mirapex may affect postsynaptic dopamine receptors in the brain in order to decrease unwanted movement. Because of the sensitivity of the neural pathways, dosing of Mirapex must be conservative, with gradual increases monitored for the effect on the patient. Too high a dose of Mirapex can have some unwanted and even dangerous effects reflected in signs the patient will display.
Falling Asleep
Like other central nervous system depressants, Mirapex can have the effect of putting the person to sleep. The RxList website states a sign of taking too much Mirapex is falling asleep, sometimes without the precursor of feeling tired. Along with drowsiness, you may feel dizzy, confused or light headed if you take too much Mirapex. The usual cautions against driving or operating machinery while taking Mirapex are especially relevant if there is a possibility you are taking too much of the drug.
Fainting
Patients taking Mirapex may experience a sudden rush of lightheadedness or weakness when taking too much of the drug. Drugs.com warns there is a danger of falling and accidental injury if too much Mirapex is ingested and oxygen flow to the brain is limited.
Hearing Voices
Too much Mirapex may make you experience hallucinations. Mayo Clinic staff say you may experience feelings of altered realities and think people and things are present when they aren't. Elderly patients are especially sensitive to this difficulty and should be monitored so they don't act on their mistaken perception of reality.
Compulsive Eating or Gambling
Patients taking Mirapex at increasing dosages have reported a loss of normal protective restraints on their behavior. Mayo Clinic staff say some patients report compulsive gambling, eating or sexual behavior while using Mirapex. These behaviors indicate too high a dose of the medication.
