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.

What is Patient Information Overview?
A concise overview of the drug for the patient or caregiver from First DataBank.
Eldepryl Overview - Patient Information: Side Effects
If you are also taking levodopa, you may experience more side effects from the levodopa when taking selegiline. Tell your doctor immediately if any of these side effects occur: nausea, shakiness, muscle stiffness, mental/mood changes such as hallucinations/abnormal dreams. Your doctor may need to change your medication or dose. Do not stop or change the dose of your levodopa without talking with your doctor first.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Some people taking selegiline have fallen asleep suddenly during their usual daily activities (such as talking on the phone, driving). In some cases, sleep occurred without any feelings of drowsiness beforehand. This sleep effect may occur anytime during treatment with selegiline, including up to 1 year after starting the medication. If you experience increased sleepiness or fall asleep during the day, do not drive or take part in other possibly dangerous activities until you have discussed this effect with your doctor. Your risk of this sleep effect is increased by using alcohol or other medications that can make you drowsy. See also Precautions section.
Tell your doctor right away if you have any serious side effects, including: fainting, loss of balance, mental/mood changes (e.g., agitation, confusion, depression, hallucinations), unusual strong urges (such as increased gambling, increased sexual urges), worsening muscle stiffness/twitching, changes in sexual ability/interest, increased shaking (tremor), swollen ankles/legs, difficulty urinating, unusual weight gain, easy bleeding/bruising, black/tarry stools, vomit that looks like coffee grounds.
This drug may rarely cause an attack of extremely high blood pressure (hypertensive crisis), which may be fatal. Many drug and food interactions can increase this risk. (See also Drug Interactions section.) Get medical help right away if any of these serious side effects occur: frequent/severe headache, fast/slow/irregular/pounding heartbeat, chest pain, neck stiffness/soreness, severe nausea/vomiting, sweating/clammy skin (sometimes with fever), widened pupils, vision changes (e.g., double/blurred vision), sudden sensitivity to light (photophobia).
This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take. Get medical help right away if you develop some of the following symptoms: hallucinations, unusual restlessness, loss of coordination, fast heartbeat, severe dizziness, unexplained fever, severe nausea/vomiting/diarrhea, twitching muscle.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Eldepryl FDA Prescribing Information: Side Effects
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.
INCIDENCE OF TREATMENT-EMERGENT ADVERSE EXPERIENCES IN THE PLACEBO-CONTROLLED CLINICAL TRIAL
|Adverse Event||Number of Patients Reporting Events|
|The following events were reported once in either or both groups|
|Low back pain||1||0|
In all prospectively monitored clinical investigations, enrolling approximately 920 patients, the following adverse events, classified by body system, were reported.
Central Nervous System
