For uncomplicated urethritis caused by susceptible organisms, the typical Bactrim dosage is two double-strength tablets (1600 mg sulfamethoxazole and 320 mg trimethoprim) once daily for 14 days.
Always follow your doctor’s instructions. Dosage may vary depending on individual factors.
- Alternative Regimen: Your doctor might prescribe a different dosage or duration, potentially using single-strength tablets. Missed Dose: Take the missed dose as soon as you remember, unless it’s almost time for your next dose. Never double the dose. Complete the Course: Finish all the medication, even if you feel better before the course ends. Stopping early increases the risk of recurrence.
Important Considerations:
- Bactrim is not suitable for treating all types of urethritis. Your doctor needs to identify the causative agent. Inform your doctor about any allergies, especially to sulfa drugs or trimethoprim. Discuss potential drug interactions with your doctor before starting treatment. Report any side effects, such as rash, nausea, or unusual fatigue, to your doctor immediately. This information does not replace a consultation with your healthcare provider. Always seek medical advice for your specific situation.
Pregnancy and Breastfeeding: Use of Bactrim during pregnancy and breastfeeding requires careful consideration and should be discussed with your doctor.
Pregnancy: Bactrim use during pregnancy carries potential risks and should only be used when the benefits outweigh the potential risks. Breastfeeding: Bactrim can pass into breast milk. Discuss the risks and benefits with your healthcare provider before using this medicine while breastfeeding.
