What Is Doxycycline Used For? A Complete Guide

Doxycycline is a broad-spectrum antibiotic belonging to the tetracycline class, widely used to treat various bacterial infections. Its versatility makes it a go-to medication for respiratory tract infections, urinary tract infections (UTIs), skin infections, and certain sexually transmitted infections (STIs), such as chlamydia and syphilis. Doxycycline is also commonly prescribed for acne, especially when inflammation is moderate to severe. Beyond typical bacterial infections, doxycycline plays a vital role in treating and preventing malaria when traveling to certain high-risk regions. It’s also used to manage tick-borne illnesses like Lyme disease and Rocky Mountain spotted fever. In patients with rosacea, it helps reduce skin redness and pimples due to its anti-inflammatory properties. This medication is available in tablet, capsule, and suspension form, usually taken once or twice daily, depending on the condition.
