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.
硫酸亚铁与四环素及其三种衍生物——土霉素、甲烯土霉素和强力霉素——一起服用时，会严重损害这些抗生素的吸收。因此，在四环素治疗期间，即使同时服用小剂量的铁也应避免。
