Applies to selegiline: compounding powder, oral capsule, oral tablet, oral tablet disintegrating, transdermal film extended release
The most hazardous consequence of inhibition of MAO A is the potential for hypertensive crises. Such crises may be precipitated by ingestion of foods containing large amounts of exogenous amines (like tyramine) or concomitant use of medications containing indirect or mixed-acting sympathomimetic amines. At the usual therapeutic dose (10 mg per day), inhibition of MAO A generally does not occur and the manufacturer reports that patients may safely take selegiline (the active ingredient contained in Eldepryl) without dietary restrictions. (For a list of foods which contain a large amount of tyramine, please see the "Interactions" section of this program). Patients should be instructed, however, to avoid over-the-counter cold remedies and other preparations which may contain vasoactive amines.
Selegiline is generally well tolerated. At the usual therapeutic dose (10 mg per day), selegiline provides selective inhibition of MAO B. At higher doses, loss of selectivity may occur and patients may be at risk of side effects related to inhibition of MAO A.
Exacerbation of preexisting ulcer disease with severe upper gastrointestinal bleeding has been reported.
Gastrointestinal side effects have been reported the most frequently. These have included constipation, flatulence, anorexia, gastroenteritis, vomiting, increased appetite, thirst, periodontal abscess, eructation, gastritis, colitis, dysphagia, tongue edema, glossitis, increased salivation, melena, tongue disorder, tooth caries. Gastrointestinal neoplasia and rectal hemorrhage have also been reported rarely. Irritation of the buccal mucosa has been reported with the use of the orally disintegrating tablet.
Nervous system side effects have included agitation, paresthesia, thinking abnormal, amnesia, lag cramps, tremor, vertigo, hypertonia, twitching, emotional lability, confusion, manic reaction, depersonalization, hyperkinesias, hostility, myoclonus, circumoral paresthesia, hyperesthesia, increased libido, euphoria, neurosis, paranoid reaction. Ataxia has also been reported rarely. Data from postmarketing spontaneous reporting include a seizure in a dialyzed chronic renal failure patient. A clear causal relationship to selegiline (the active ingredient contained in Eldepryl) was not established.
Patients taking levodopa-carbidopa may experience worsening of side effects attributable to levodopa. Dosage reduction of levodopa-carbidopa may be necessary.
Muscle twitch and myoclonic jerks have been reported at doses greater than 10 mg/day.
Impaired memory, transient high, and increase energy have been reported at doses greater than 10 mg/day.
Psychiatric side effects have included hallucinations, confusion, anxiety, mania, hypomania, psychosis, depression, other mood changes, nightmares, and hypersexuality. Reversible transvestic fetishism has been reported in a 72-year-old man with Parkinson's disease after selegiline 5 mg oral twice daily was added to his therapy for motor fluctuations. After the selegiline was stopped, his urge to wear women's clothing stopped.
Cardiovascular side effects have included hypertension, vasodilation, tachycardia, migraine, syncope, atrial fibrillation, peripheral vascular disorder, and myocardial infarct.
Inhibition of MAO A may cause hypertensive crises if foods containing large amounts of exogenous amines (like tyramine) are consumed. Tyramine-rich foods and beverages should be avoided beginning on the first day of therapy with the transdermal system of selegiline 9 mg/24 hours or 12 mg/24 hours, and should continue to be avoided for two weeks after a dose reduction to 6 mg/24 hours or following the discontinuation of the 9 mg/24 hours or 12 mg/24 hours treatment. Patients receiving the higher doses should follow the recommended "Dietary Modifications Required for Patients Taking EMSAM 9 mg/24 hours and 12 mg/24 hours." If a hypertensive crisis occurs, the drug should be discontinued immediately and therapy to lower blood pressure should be instituted.
Anticholinergic effects have been reported and include dry mouth, blurred vision, urinary retention and constipation.
