Permax (pergolide mesylate) is an ergot derivative dopamine receptor agonist is used to treat the stiffness, tremors, spasms, and poor muscle control of Parkinson's disease. It is often used in conjunction with other medicines in the treatment of Parkinson's disease. The brand name of this medication is discontinued, but generic versions may be available. Common side effects include nausea, vomiting, upset stomach, decreased appetite, diarrhea, constipation, dry mouth, drowsiness, insomnia, agitation, or anxiety.

The dosage may then be increased by 0.25 mg/day every third day until an optimal therapeutic dosage is achieved. Permax may interact with phenothiazines, haloperidol, thiothixene, metoclopramide, or other drugs that cause drowsiness or dizziness, including antidepressants, alcohol, sedatives, pain relievers, other anxiety medicines, muscle relaxants, and antihistamines.

Permax FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

Commonly Observed

In premarketing clinical trials, the most commonly observed adverse events associated with use of pergolide mesylate which were not seen at an equivalent incidence among placebo-treated patients were:

Associated With Discontinuation of Treatment

Twenty-seven percent (27%) of approximately 1,200 patients receiving pergolide mesylate for treatment of Parkinson†s disease in premarketing clinical trials in the US and Canada discontinued treatment due to adverse events. The events most commonly causing discontinuation were related to the nervous system (15.5%), primarily hallucinations (7.8%) and confusion (1.8%).

Fatalities-See WARNINGS.

Incidence in Controlled Clinical Trials

The table that follows enumerates adverse events that occurred at a frequency of 1% or more among patients taking pergolide mesylate who participated in the premarketing controlled clinical trials comparing pergolide mesylate with placebo. In a double-blind, controlled study of 6 month†s duration, patients with Parkinson†s disease were continued on l-dopa/carbidopa and were randomly assigned to receive either pergolide mesylate or placebo as additional therapy.

The prescriber should be aware that these figures cannot be used to predict the incidence of side effects in the course of usual medical practice where patient characteristics and other factors differ from those which prevailed in the clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigations involving different treatments, uses, and investigators. The cited figures, however, do provide the prescribing physician with some basis for estimating the relative contribution of drug and nondrug factors to the side-effect incidence rate in the population studied.

Events Observed During the Premarketing Evaluation of Permax (pergolide mesylate)

This section reports event frequencies evaluated as of October 1988 for adverse events occurring in a group of approximately 1,800 patients who took multiple doses of pergolide mesylate. The conditions and duration of exposure to pergolide mesylate varied greatly, involving well-controlled studies as well as experience in open and uncontrolled clinical settings. In the absence of appropriate controls in some of the studies, a causal relationship between these events and treatment with pergolide mesylate cannot be determined.

The following enumeration by organ system describes events in terms of their relative frequency of reporting in the data base. Events of major clinical importance are also described in the Warnings and Precautions sections.

The following definitions of frequency are used: frequent adverse events are defined as those occurring in at least 1/100 patients; infre-quent adverse events are those occurring in 1/100 to 1/1,000 patients; rare events are those occurring in fewer than l/1,000 patients.
