Bactrim DS Tablet (Sulfamethoxazole + Trimethoprim) used to treat Bacterial Infections Affecting Urinary, Respiratory & Skin Areas
Bactrim DS Tablet contains Sulfamethoxazole and Trimethoprim, a combination used for managing various bacterial infections. It works by preventing bacterial growth and helps treat infections affecting the urinary tract, respiratory system, skin, and other areas.
Product Overview
Bactrim DS Tablet is a combination formulation containing Sulfamethoxazole and Trimethoprim, two antibacterial components that work together to control the growth and spread of susceptible bacteria. This combination is commonly known as co-trimoxazole and provides a dual mechanism of action for effective bacterial control. Bacterial infections occur when harmful bacteria multiply and cause inflammation, discomfort, or tissue damage. Bactrim DS works by interfering with the production of essential substances required by bacteria for survival and reproduction, helping reduce the infection.
Product Composition
- Sulfamethoxazole – A sulfonamide antibacterial component that blocks bacterial folate production required for growth
- Trimethoprim – Works by inhibiting another step in bacterial folate metabolism
- Dual Antibacterial Action – Provides combined activity against susceptible bacteria
- Oral Tablet Formulation – Provides convenient administration for systemic infection management

Administration Instructions
Take exactly as advised
Bactrim DS Tablet should be taken in the recommended dose and schedule. Changing the dose without guidance may reduce effectiveness or increase the risk of unwanted effects.
Complete the full course
Continue taking the medicine for the advised duration, even if symptoms improve earlier, to help prevent the infection from returning.
