Permax® (pergolide mesylate)

Permax and is sold and manufactured as the generic drug pergolide by Par and Teva Pharmaceutical Industries and marketed by Valeant Pharmaceuticals International under the tradename pergolide as well. Permax is a member of a class of drugs known as dopamine agonists and is used with levodopa and carbidopa to manage the signs and symptoms (tremors and slowness of movement) of Parkinson’s disease.

Why is Permax prescribed?

Prior to an FDA recall in March of 2007, the drug was used to treat Parkinson’s disease, a motor system disorder which causes tremors in the hands, arms, legs, jaw, and face as well as impaired balance and coordination. The drug was also used to control restless leg syndrome.

Permax warnings and alerts

In March of 2007, the FDA notified consumers that companies manufacturing and distributing pergolide have agreed to withdraw this drug from the market due to the potential for heart valve damage. Two new studies showed that patients with Parkinson’s disease who were treated with pergolide had an increased chance of serious damage to their heart valves when compared to patients who did not receive the drug.

Permax FAQs

I am currently taking Permax for Parkinson’s Disease, what should I do?

Immediately contact your doctor to discuss alternate treatment options. Do not discontinue use of Permax until you speak with your doctor as stopping pergolide too quickly can cause other harmful side effects and at least three other effective treatments are available that are not associated with damage to heart valves.

Why is is the FDA recalling Permax?

The FDA is responding to two recent New England Journal of Medicine studies which confirm previous findings tying pergolide to increased chance of regurgitation (backflow of blood) of the mitral, tricuspid, and aortic valves of the heart.
Valve regurgitation is a condition in which valves don’t close tightly, allowing blood to flow backward across the valve. Symptoms include shortness of breath, fatigue and heart palpitations.

If I am no longer taking Permax do I still have a legal claim?

Possibly. The recent FDA findings raise serious legal concerns for patients who have taken Permax or the families of former Permax patients who died from heart failure or heart-related conditions during or after use of the drug.

Can I file a lawsuit if I have suffered damages from taking Permax?

Possibly. While all medications have certain, anticipated side effects, a drug manufacturer has a duty to inform physicians adequately regarding the known risks associated with its drugs. If a manufacturer fails to do so, it can be held responsible to patients who are injured as the result of inadequate warnings, under a legal theory known as “product liability.” Depending upon the particular circumstances of your case, damages may include recovery for any of the following:

  • Past and future medical expenses
  • Past and future pain and suffering
  • Lost wages
  • Loss of future earning capacity
  • Emotional distress

If you or a loved one has experienced any health problems while taking Permax, you should contact your doctor immediately. You may also wish to contact an experienced Permax lawyer to discuss your legal options. As all legal claims are subject to time limits, however, you may risk forfeiture of your right to financial compensation if you delay.
