Drug Interaction Report

Using vilanterol together with safinamide may increase cardiovascular side effects such as heart palpitations, chest pain, increased heart and pulse rates, and blood pressure elevations. The risk exists even when vilanterol or similar medications are given by oral inhalation directly into the lungs, and more so if these products are overused. Talk to your doctor before using these medications if you have a history of heart disease or high blood pressure. Depending on your condition, it may be preferable to wait at least 14 days after you are off safinamide before you start using vilanterol. Do not exceed the dose and frequency of use of vilanterol recommended on the product label or prescribed by your doctor. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Safinamide may be taken with or without food. While there is no need to strictly avoid most foods and beverages that contain tyramine (usually aged, fermented, cured, smoked, or pickled foods such as air-dried and fermented meats or fish, aged cheeses, most soybean products, yeast extracts, red wine, beer, and sauerkraut) during treatment with safinamide, certain foods such as some of the aged cheeses (for example, Boursault, Liederkrantz, Mycella, and Stilton) and pickled herring may contain very high amounts of tyramine and should generally be avoided if possible. Consumption of very high levels of tyramine (greater than 150 mg) while on safinamide treatment may lead to dangerous increases in your blood pressure, a condition known as hypertensive crisis. Talk to your doctor or pharmacist if you are uncertain about what foods, if any, to avoid. You should seek immediate medical attention if you experience sudden and severe headache, blurred vision, confusion, seizures, chest pain, nausea or vomiting, sudden numbness or weakness (especially on one side of the body), speech difficulties, fever, sweating, lightheadedness, and/or fainting during treatment with safinamide, as these may be signs and symptoms of a hypertensive crisis. Do not take larger doses or use the medication more frequently than prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
