Co-trimoxazole

Introduction

Co-trimoxazole is a combination antibiotic medicine made of two drugs: Sulfamethoxazole and Trimethoprim. It is commonly used to treat bacterial infections in different parts of the body. This medicine works by stopping the growth of bacteria and helping the body fight infections effectively. Doctors usually prescribe Co-trimoxazole for urinary tract infections (UTI), respiratory infections, ear infections, and certain stomach infections. It is also used in some cases to treat and prevent specific infections in people with low immunity. Always use this medicine only as advised by your doctor.

• Respiratory tract infections (bronchitis, pneumonia)

• Ear infections (otitis media)

How Co-trimoxazole Works

Co-trimoxazole blocks two different bacterial enzymes needed to produce folic acid, a vital nutrient for bacterial growth. This dual action effectively stops the infection from spreading.
