trimethoprim-sulfamethoxazole

Trimethoprim-sulfamethoxazole is a combination antibiotic used to treat various bacterial infections, such as urinary tract infections, bronchitis, and certain types of diarrhea. It works by blocking two different steps in the bacteria’s ability to produce more bacteria, effectively stopping their growth and allowing the body's immune system to eliminate the infection. This medication is effective against many bacteria but should only be used under a healthcare provider’s guidance to ensure safety and appropriateness. Common side effects may include gastrointestinal discomfort, rash, or allergic reactions.
