Interactions between your drugs

Moderate

phenylpropanolamine safinamide

Applies to: Multihistamine-D (pheniramine / phenylpropanolamine / phenyltoloxamine / pyrilamine) and Xadago (safinamide)

Using safinamide together with phenylpropanolamine may increase cardiovascular side effects such as blood pressure elevations and increased heart rate. While these effects are not expected to be dangerous in most people, there is a possibility for high blood pressure to occur which may require medical attention. Talk to your doctor if you have any questions or concerns, especially if you have a history of high blood pressure, irregular heart rhythm, or heart disease. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. 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 food

Applies to: Xadago (safinamide)

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.

phenylpropanolamine food

Applies to: Multihistamine-D (pheniramine / phenylpropanolamine / phenyltoloxamine / pyrilamine)

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.
