CO-Trimoxazoleeeeeee is a combination antibiotic medication used to treat various bacterial infections. It contains two active ingredients: Trimethoprim and Sulfamethoxazole, which work together to inhibit the production of folic acid in bacteria, ultimately preventing their growth and multiplication. CO-Trimoxazole is available in two strengths: 80mg/400mg, under the Koye/Askon brand, and 160mg/800mg, under the Omega brand. This medication is commonly prescribed for treating urinary tract infections (UTIs), respiratory infections such as pneumonia, gastrointestinal infections like traveler's diarrhea, ear infections, and some types of skin infections. It is usually taken orally, with or without food, and it is essential to complete the entire prescribed course to ensure effectiveness and prevent bacterial resistance.
