If your doctor mentioned trimethoprim, you probably want straight answers: what it treats, how to take it, and what could go wrong. Trimethoprim is a short-course antibiotic most often used for urinary tract infections (UTIs). It works by blocking bacterial folate production, which stops bacteria from growing.
Trimethoprim is usually prescribed for uncomplicated UTIs in women and some other bacterial infections. Typical adult dosing for a UTI is 200 mg every 12 hours for 3 days or 100 mg every 12 hours for 3 days, depending on local guidelines and the product. Always follow your prescriber's directions — doses vary by country, infection type, and kidney function.
Take the medicine with water. You can take it with or without food. Finish the full course even if you feel better after a day or two — stopping early can let resistant bacteria survive.
Common side effects include nausea, headache, and a skin rash. Most people tolerate trimethoprim well, but watch for signs of a severe reaction: high fever, yellowing of the skin or eyes, dark urine, or severe rash. Stop the drug and seek medical help if these appear.
Trimethoprim can interact with other medicines. It may raise levels of drugs like methotrexate or warfarin and can add to blood disorder risks when combined with certain HIV drugs. It may also affect potassium levels, so people on ACE inhibitors, ARBs, or potassium supplements should be monitored.
Pregnancy and breastfeeding: Trimethoprim interferes with folate and is usually avoided in early pregnancy unless the benefit clearly outweighs the risk. If you're pregnant or breastfeeding, talk to your clinician; they may recommend a safer alternative.
Kidney disease: Dosing needs adjustment if your kidneys are not working well. Older adults often need lower doses and closer monitoring for side effects.
Antibiotic resistance is real. If your symptoms don't improve in 48–72 hours, contact your provider — you may need a urine test and a different antibiotic. Don't reuse leftover antibiotics without medical advice.
