What is Bactrim (Sulfamethoxazole and Trimethoprim)?
Bactrim combines two antibiotics: sulfamethoxazole and trimethoprim. These work synergistically to inhibit the growth and replication of bacteria by interfering with the synthesis of folic acid, an essential nutrient for bacteria. This dual action helps effectively eliminate infections caused by susceptible bacteria.
Dosage of Bactrim (Sulfamethoxazole and Trimethoprim)
- For adults and children over 12 years, the common dosage is one Bactrim DS tablet (160 mg trimethoprim / 800 mg sulfamethoxazole) twice daily.
- The dose and duration depend on the infection type and individual patient factors.
- Children under 12 years receive doses based on age and weight, usually as an oral suspension.
- Always follow the healthcare provider’s prescribed dose and treatment length.
Typically one tablet twice daily for adults; children’s dosing is weight-based.
