Eldepryl (selegiline hydrochloride) is a monoamine oxidase type B (MAO-B) inhibitor prescribed for the management of the symptoms of Parkinson's disease in patients already taking levodopa-carbidopa (also a drug prescribed for the treatment of Parkinson's disease). Side effects of Eldepryl include fainting, dry mouth, nausea, vomiting, heartburn diarrhea, gas, constipation, dizziness, weakness, sleep problems (insomnia), runny or stuffy nose, back pain, mouth sores or ulcers, or pain with swallowing (while using Zelapar).
Eldepryl is available in 5mg capsules. The recommended regimen for the administration Eldepryl is 10 mg per day administered as divided doses of 5 mg each taken at breakfast and lunch. Eldepryl may interact with carbamazepine, diet pills or cold medicines that contain ephedrine, pseudoephedrine, or phenylephrine, nafcillin, phenobarbital, rifampin, or antidepressants. Tell your doctor all medications and supplements you use. There are no adequate and well-controlled studies of Eldepryl in pregnant women or in the pediatric population. Selegiline should be used during pregnancy only is the potential benefit justifies the potential risk to the fetus. It is not known selegiline hydrochloride is excreted in human milk.
Our Eldepryl (selegiline hydrochloride) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

The number of patients who received selegiline in prospectively monitored pre-marketing studies is limited. While other sources of information about the use of selegiline are available (e.g., literature reports, foreign post-marketing reports, etc.) they do not provide the kind of information necessary to estimate the incidence of adverse events. Thus, overall incidence figures for adverse reactions associated with the use of selegiline cannot be provided. Many of the adverse reactions seen have also been reported as symptoms of dopamine excess.
Moreover, the importance and severity of various reactions reported often cannot be ascertained. One index of relative importance, however, is whether or not a reaction caused treatment discontinuation. In prospective pre-marketing studies, the following events led, in decreasing order of frequency, to discontinuation of treatment with selegiline: nausea, hallucinations, confusion, depression, loss of balance, insomnia, orthostatic hypotension, increased akinetic involuntary movements, agitation, arrhythmia, bradykinesia, chorea, delusions, hypertension, new or increased angina pectoris, and syncope. Events reported only once as a cause of discontinuation are ankle edema, anxiety, burning lips/mouth, constipation, drowsiness/lethargy, dystonia, excess perspiration, increased freezing, gastrointestinal bleeding, hair loss, increased tremor, nervousness, weakness, and weight loss.
Experience with ELDEPRYL (selegiline hcl) obtained in parallel, placebo controlled, randomized studies provides only a limited basis for estimates of adverse reaction rates. The following reactions that occurred with greater frequency among the 49 patients assigned to selegiline as compared to the 50 patients assigned to placebo in the only parallel, placebo controlled trial performed in patients with Parkinson's disease are shown in the following Table. None of these adverse reactions led to a discontinuation of treatment.
