Doxycycline is a tetracycline-class antibiotic that works by inhibiting bacterial protein synthesis. It is a broad-spectrum antibiotic, meaning it is effective against a wide range of bacteria. It is commonly prescribed for various bacterial infections, including respiratory tract infections, urinary tract infections, skin infections, sexually transmitted infections, and certain tick-borne diseases like Lyme disease and Rocky Mountain spotted fever. Doxycycline is also used in the prevention of malaria and in the treatment of acne and rosacea, owing to its anti-inflammatory properties at lower doses. It is available in several oral formulations, including capsules, tablets, and a liquid suspension, and can also be administered intravenously in hospital settings. The exact dose and duration of treatment depend on the specific infection being treated, the patient's age and weight, and their overall health status. (DrugBank, FDA label)
