    Abstract

    Ferrous sulphate administered together with tetracycline and three of its derivatives—oxytetracycline, methacycline, and doxycycline—was found seriously to impair the absorption of these antibiotics. Thus even small doses of iron taken simultaneously should be avoided during tetracycline treatment.
