Treatment Sun protection, both mechanical and pharmacologic, while taking te tracycline.
Discussion Tetracyclines are bacteriostatic antibiotics that bind to the SOS ribosomal unit, blocking synthesis ol protein by preventing attachment of aminoacyl-tRNA. If they are taken with alkaline foods such as milk and antacids, GI absorption is decreased. Tetracycline is used both therapeutically and prophylactically for chlamydial genitourinary infections, Lyme disease, tularemia, cholera, and acne. Other side effects include brownish discoloration of the teeth in children (contraindicated in pregnancy), photosensitivity, aminoaciduria, proteinuria, phosphaturia, acidosis, and glycosuria (a Fanconi-like syndrome associated with "expired" tetracycline).
