Diet Changes When Taking Isoniazid (INH) Isoniazid (brand name Nydrazid) is an antibiotic medicine. It is most commonly used to prevent or treat tuberculosis. It is important that you take the medicine exactly as prescribed by your doctor. There are some diet changes that you need to make to take this medicine safely. These changes will help prevent side effects and make the medicine work well in your body. When You Take the Medicine Take this medicine on an empty stomach at least 1 hour before or 2 hours after eating. Food in your stomach decreases the amount of isoniazid your body can absorb. Do not drink alcohol when taking this medicine. Ask your doctor or pharmacist about taking a supplement of vitamin B6 (pyridoxine) while you take this medicine. Take vitamins, including vitamin B6 (pyridoxine), mineral supplements, or antacids separately at least 2 hours apart from this medicine. Increase your intake of folate (vitamin B9), niacin (vitamin B3) and magnesium while take isoniazid. Good food sources include: dark leafy greens, pinto or garbanzo beans, peanuts, Brazil nuts, almonds, cashews, asparagus, rice, wheat, flaxseed, molasses and cocoa powder. Avoid foods that contain histamine such as tuna, herring, mackerel, sardines, shellfish, anchovies, mushrooms, tomatoes, spinach, eggplant, and vinegar, or foods containing vinegar such as salad dressings and pickles. Avoid foods that contain tyramine. See the table on the next two pages for a listing of foods with tyramine. Diet changes should be continued for 2 weeks after stopping isoniazid. © Copyright 2010 - March 25, 2013.
