Prexorise ER 1.5 Tablet 10's is used to treat the symptoms of Parkinson's disease and moderate to severe Willis-Ekbom disease (restless legs syndrome) in adults. It contains Pramipexole, which works by mimicking the action of dopamine (acting in place of dopamine), a natural substance found in the brain needed to control body movement. This triggers the nerve impulses in the brain that control body movements. In some cases, you may experience certain common side effects such as sleepiness, nausea, constipation, dizziness, fatigue, hallucinations, dry mouth, muscle spasms, and peripheral oedema (leg swelling due to fluid overload). Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
