Trimethoprim is an antibiotic medication used to treat a variety of bacterial infections . It's available in tablet, capsule, and liquid forms, and is sometimes prescribed in combination with other antibiotics like sulfamethoxazole. Here's a closer look at trimethoprim:

• Uses: Treats urinary tract infections (UTIs), bronchitis, middle ear infections, traveler's diarrhea, pneumocystis pneumonia (PCP) [1, 2, 3].
• How it works: Trimethoprim works by stopping the growth of bacteria. It does this by interfering with their production of folic acid, a substance bacteria need to survive [1, 4].
• Dosage: Dosage depends on the type of infection being treated, your age, and kidney function [5]. It's important to follow your doctor's instructions exactly regarding dosage and duration of use.
• Availability: Trimethoprim is available by prescription only [5].

Important things to remember:

• Antibiotics like trimethoprim should only be used to treat bacterial infections, not viral infections (like the common cold or flu). Using antibiotics when not needed can increase your risk of developing antibiotic resistance later [6].
• There can be side effects, so talk to your doctor before using trimethoprim, especially if you have any underlying health conditions [5].
• It may interact with other medications you're taking, so be sure to tell your doctor about all your medications [5].
