Dopamine is a chemical in the brain known to be absent or reduced in people with Parkinsons disease. Generic Symmetrel is thought to increase the release of dopamine in the brain. By increasing dopamine release, Generic Symmetrel has a mild effect against some of the symptoms of Parkinsons disease such as tremor and rigidity. However, after a period of time, many people observe a reduction in the effect achieved from the same dose (tolerance develops) and therefore its use may be limited. Sometimes the effectiveness can be restored if use of the drug is stopped for a period of time and then restarted. Generic Symmetrel is often used in combination with other medicines for the treatment of Parkinsons disease.
