Tetracycline Anti Infectives

May 8, 2026

This document details tetracycline antibiotics, a class of natural and semisynthetic compounds that interfere with bacterial protein synthesis. They are frequently prescribed as an alternative to penicillin for patients with allergies to penicillin or cephalosporins. The document outlines a comprehensive list of indications for tetracycline use, including various rickettsial diseases such as Rocky Mountain spotted fever and typhus fever, intestinal amebiasis, certain skin and soft tissue infections, uncomplicated urethral, endocervical, or rectal infections caused by Chlamydia trachomatis, and as an adjunctive treatment for severe acne. Furthermore, tetracyclines are noted for their role in the eradication of Helicobacter pylori when used in combination with metronidazole and bismuth subsalicylate. Potential side effects are also enumerated, encompassing nausea, vomiting, diarrhea, epigastric distress, stomatitis, sore throat, skin rashes, and photosensitivity reactions, with specific mention that demeclocycline is most likely to cause severe photosensitivity while minocycline is least likely. Contraindications and precautions are emphasized, including hypersensitivity to sulfonamides, use during lactation and pregnancy, and administration to children younger than 9 years due to the risk of tooth discoloration. The document also advises caution for women of childbearing age regarding oral contraception use when tetracyclines are prescribed. Crucially, it warns against concurrent administration with dairy products, antacids, laxatives, or products containing iron, specifying that such products should be taken at least 2 hours before or after tetracyclines to prevent interference with absorption due to the presence of calcium, magnesium, aluminum, or iron.
