Doxicap is a broad-spectrum antibiotic containing Doxycycline Hydrochloride. It belongs to the tetracycline group and works by inhibiting bacterial protein synthesis, effectively stopping the growth of various Gram-positive and Gram-negative bacteria. Produced by Renata PLC, it is one of the most commonly prescribed antibiotics in Bangladesh for respiratory, skin, and sexually transmitted infections. Here is the updated guide for 2026.
