四環黴素（Tetracycline）會引起光敏感反應（Photosensitivity），使皮膚對紫外線極度敏感，容易產生嚴重曬傷，因此衛教重點之一為避免曝曬。此外，四環黴素易與多價陽離子（如鈣、鎂、鋁、鐵）結合，產生螯合反應（Chelation），導致藥物吸收率大幅下降，故病人應避免與乳製品、抗酸劑或鐵劑同時服用。
Tetracycline causes photosensitivity, so clients should be instructed to avoid prolonged sun exposure to prevent severe burns. Additionally, they should avoid taking the medication with dairy, antacids, or iron supplements, as these can chelate the drug and reduce its absorption.
