For uncomplicated UTIs, a common regimen involves sulfamethoxazole/trimethoprim (SMX/TMP) taken twice daily for 3 days. The typical adult dosage is one double-strength tablet (800/160 mg) twice daily. Children’s dosages vary by weight; consult a pediatrician for precise instructions.
Alternative Regimens and Considerations
Another option is a 5-7 day course at the same dosage. Always follow your doctor’s specific instructions regarding dosage and duration. Certain factors, like allergies or kidney problems, may require alternative antibiotics or adjusted dosages. Complete the entire course of medication, even if symptoms improve, to prevent recurrence. If symptoms worsen or don’t improve after a few days, seek medical attention immediately.
