What is Azilect?
Azilect (rasagiline) works by increasing the levels of certain chemicals in the brain.
Azilect is used to treat symptoms of Parkinson's disease (stiffness, tremors, spasms, poor muscle control).
Azilect is sometimes used with another medicine called levodopa.
Do not Azilect if you have used a MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, selegiline, or tranylcypromine.
Tell your doctor about all medicines you have used in the 2-week period before you start taking Azilect. Many drugs can interact with rasagiline, and some drugs should not be used together.
Before you take this medicine, tell your doctor if you have liver disease.
There are many other drugs that can cause serious medical problems if you take them together with Azilect. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor. Keep a list of all your medicines and show it to any healthcare provider who treats you.
While you are taking this medicine and for 2 weeks after you stop taking it, you may not be able to eat certain types of cheese. Follow your doctor's instructions. Rasagiline may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Before taking this medicine
You should not take Azilect if you are allergic to rasagiline.
Do not use Azilect if you have used any other MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, selegiline, tranylcypromine, and others.
Some medicines can cause unwanted or dangerous effects when used with Azilect. Your doctor may change your treatment plan if you also use:
cyclobenzaprine (a muscle relaxer);
dextromethorphan (contained in many over-the-counter cough medicines);
St. John's wort; or
Be sure your doctor knows if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, migraine headaches, serious infections, or prevention of nausea and vomiting. These medicines may interact with rasagiline and cause a serious condition called serotonin syndrome.
To make sure Azilect is safe for you, tell your doctor if you have ever had:
It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
It may not be safe to breast-feed while using this medicine. Ask your doctor about any risk.
How should I take Azilect?

If you take Azilect alone, your dose may be different than if you take it with other Parkinson's medications. Follow your doctor's dosing instructions very carefully.
Azilect may be only part of a complete program of treatment that also includes a special diet. Follow the diet plan created for you by your doctor or nutrition counselor.
Get familiar with the list of foods you should avoid to help prevent certain side effects of rasagiline.
Call your doctor if your Parkinson's symptoms do not improve, or if they get worse while using Azilect.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of rasagiline can be fatal.
Overdose symptoms may include drowsiness, dizziness, severe headache, rapid pulse, feeling agitated or irritable, muscle spasms in your neck or jaw, sweating, cold or clammy skin, shallow breathing, fainting, or seizure (convulsions). These symptoms may be delayed for 12 to 24 hours after an overdose.
What should I avoid while taking Azilect?
Avoid driving or hazardous activity until you know how this medicine will affect you. Dizziness or drowsiness can cause falls, accidents, or severe injuries. Avoid getting up too fast from a sitting or lying position, or you may feel dizzy.
Avoid drinking alcohol, especially red wine, vermouth, and tap beers or ale.
Also avoid eating foods that are high in tyramine, such as aged cheeses, fava beans, soy sauce, herring, pickled or processed meats and fish, and meats that are aged, dried, smoked, or fermented. Eating tyramine while you are taking Azilect can raise your blood pressure to dangerous levels which could cause life-threatening side effects.
