Bactrim vs. Bactrim DS
A healthcare provider may prescribe Bactrim® (sulfamethoxazole/trimethoprim) to treat several infections and to prevent one particular infection, Pneumocystis carinii pneumonia, in people with a weakened immune system. This prescription antibiotic is available in two forms:
- Bactrim tablets -- 80 mg of trimethoprim and 400 mg of sulfamethoxazole
- Bactrim DS ("double strength") tablets -- 160 mg of trimethoprim and 800 mg of sulfamethoxazole.
Some people may wonder what the difference is between Bactrim DS vs. Bactrim. The "DS" stands for "double strength." Bactrim DS contains exactly twice as much of the active ingredients as regular Bactrim. There are no other important differences between the two products; taking two regular Bactrim tablets is the same as taking one Bactrim DS tablet.
