Should you avoid dairy products if you are taking antibiotics?

You are not allowed to take dairy products with tetracycline group of antibiotics. Tetracycline group of antibiotics are precipitated in the stomach and are not absorbed. You may take them about one hour before taking dairy products. All the other antibiotics can probably be taken with dairy products. Some antibiotics, like macrolide group of antibiotics and oral penicillin tablets are to be taken on empty stomach. Macrolide group of antibiotics include erythromycin, roxithromycin, clarithromycin and azithromycin. Empty stomach means no dairy products also.
