Avoid alcohol while taking isoniazid. Alcohol will increase the risk of damage to the liver during treatment with this medication.
Use caution with the foods listed below. They can interact with isoniazid and cause a reaction that includes a severe headache, large pupils, neck stiffness, nausea, vomiting, diarrhea, flushing, sweating, itching, irregular heartbeats, and chest pain. A reaction will not necessarily occur, but eat these foods with caution until you know if you will react to them. Call your doctor immediately if you experience any of these symptoms.
Eat the following foods with caution:
cheeses, including American, Blue, Boursault, Brick, Brie, Camembert, Cheddar, Emmenthaler, Gruyere, Mozzarella, Parmesan, Romano, Roquefort, Stilton, and Swiss;
sour cream and yogurt;
beef or chicken liver, fish, meats prepared with tenderizer, bologna, pepperoni, salami, summer sausage, game meat, meat extracts, caviar, dried fish, herring, shrimp paste, and tuna;
avocados, bananas, figs, raisins, and sauerkraut;
soy sauce, miso soup, bean curd, and fava beans;
caffeine (coffee, tea, cola, etc.); and
beer (alcoholic and nonalcoholic), red wine (especially Chianti), sherry, vermouth, and other distilled spirits.
Take care when using this medication as it can increase your risk of hepatitis. Drinking alcohol can increase this risk. You should have liver enzymes checked prior to starting the medication and monthly after starting. Report any symptoms of liver involvement like: unexplained anorexia/loss of appetite, nausea, vomiting, dark urine, rash, persistant fatique, weakness, fever lasting more than 3 days, and any upper right quadrant abdominal tenderness. These can be signs of liver problems. You should always take the medication on an empty stomach as taking it with food drastically decreases its absorption. Hope this helps!
