Bactrim, a combination of sulfamethoxazole and trimethoprim, is frequently prescribed for kidney infections (pyelonephritis). The specific dosage and treatment length depend on several factors, including the severity of the infection, your overall health, and your doctor’s assessment. Always follow your doctor’s instructions precisely.
Typical Dosage Regimen
A common adult dosage is one double-strength tablet (160 mg/800 mg sulfamethoxazole/trimethoprim) twice daily. Children’s dosages are calculated based on weight and are determined by your pediatrician. Your doctor might adjust the dosage or frequency based on your response to treatment and the results of blood and urine tests.
Treatment Duration
Treatment typically lasts for 7 to 14 days. However, a shorter course (e. g., 3-5 days) might suffice in certain cases of uncomplicated infections. Your physician will base the duration on your clinical improvement and laboratory findings. Complete the entire course of medication, even if you feel better before the prescribed duration ends. Prematurely stopping treatment can lead to recurrence or antibiotic resistance.
Important Considerations
Before starting Bactrim, inform your doctor about any allergies, pre-existing medical conditions (such as kidney or liver problems), or medications you are currently taking. During treatment, drink plenty of fluids to aid in flushing out the infection. Report any adverse effects, such as rash, nausea, or diarrhea, to your doctor immediately. Regular follow-up appointments are usually recommended to monitor progress and ensure complete eradication of the infection.
