The odds are not in your favor when a patient who is taking Permax to cope with Parkinson's disease is likely to develop critical heart valve damage problems as well. Permax is the culprit as generic Parkinson's drugs do not present life threatening side effects.Suspicions that Permax may cause heart valve damage were raised only after the drug had been on the market for some 13 years so who knows how many thousands of people have been affected by Permax injuries. Do you need an experienced Permax lawyer to determine if you have a Permax lawsuit?
