Oysitrim DS 800 mg/160 mg Tablet

Oysitrim DS 800 mg/160 mg Tablet is a prescription antibiotic tablet that contains sulfamethoxazole 800 mg and trimethoprim 160 mg in each dose. It belongs to the sulfonamide antibiotic combination class and is used to treat certain bacterial infections, including some urinary tract, respiratory, ear, and skin infections. This exact Oysitrim DS 800 mg/160 mg Tablet strength is the double-strength (DS) tablet, so it is a higher-strength form that a clinician chooses when this dose is appropriate for the infection and the patient.

How it works: Sulfamethoxazole and trimethoprim work together by blocking two steps bacteria need to make folate, a nutrient they use to grow and multiply. In the tablet form of Oysitrim DS 800 mg/160 mg Tablet, this combination helps stop susceptible bacteria from spreading so the infection can clear.

Oysitrim DS 800 mg/160 mg Tablet provides the full double-strength amount of sulfamethoxazole and trimethoprim in one tablet, which can make prescribed treatment simpler than using lower-strength tablets. Because it is a higher-strength tablet, it is meant for people whose doctor has specifically decided this dose is suitable; it should not be assumed to be interchangeable with lower-dose products or used for self-treatment.
