These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.

What should I watch for while taking this medicine?

Tell your prescriber or health care professional if your symptoms do not begin to improve in a few days or get worse.

Because furazolidone may interact with many over-the-counter medications, you must check with your prescriber before taking any non-prescription medicines while on this antibiotic. Do not treat yourself for coughs, colds, or allergies. Do not take any medications for weight loss. Some ingredients in these products may increase possible side effects.

Furazolidone can interact with certain foods that contain tyramine to produce severe headaches, a rise in blood pressure, or irregular heart beat. Foods that contain significant amounts of tyramine include aged cheeses; meats and fish (especially aged, smoked, pickled, or processed such as bologna, pepperoni, salami, summer sausage); beer and ale; alcohol-free beer; wine (especially red); sherry; hard liquor; liqueurs; avocados; bananas; figs; raisins; soy sauce; miso soup; yeast/protein extracts; bean curd; fava or broad bean pods; or any over-ripe fruit. Ask your prescriber or health care professional, pharmacist, or nutritionist for a complete listing of tyramine-containing foods. Also, avoid drinks containing caffeine, such as tea, coffee, chocolate, or cola. These dietary restrictions should be followed during the course of therapy and should be continued for 4 days after therapy has been discontinued.

Avoid alcohol during and for up to 4 days after taking furazolidone. A serious syndrome (flushing, low blood pressure, slight temperature elevation, difficulty breathing or chest pain or discomfort) can occur.

Notify your health care professional if you are scheduled to have any surgery, procedure or medical testing (including myelography); tell your prescriber or health care professional that you have been taking furazolidone.
