, Drug-related photosensitivity occurs when patients take tetracyclines, and it may continue for several
days after therapy. Milk and cheese products result in decreased levels of tetracycline when the two are
taken together. Antacids also interfere with absorption and should not be taken with tetracycline.
Counsel patients to take the entire course of prescribed antibiotic drugs, even if they feel that they are
no longer ill.
