There are two types of generic Bactrim tablets available, a double-strength formula and a regular-strength formula. These products are often sold by the name "sulfamethoxazole/TMP" on prescription labels. The FDA has determined that all generic Bactrim drugs are equivalent to the brand-name version.
Bactrim® (sulfamethoxazole/trimethoprim) is a prescription antibiotic medication used to treat a variety of different infections. It contains sulfamethoxazole (a sulfonamide, or "sulfa" antibiotic) and trimethoprim (another antibiotic that helps sulfamethoxazole to work better).
Brand-name Bactrim is manufactured by Mutual Pharmaceutical Company, Inc. and is marketed and distributed by AR Scientific. However, this medication has come off patent and is now available in generic form.
Generic Bactrim tablets are available in the following strengths:
- Sulfamethoxazole/trimethoprim 400/80 mg -- 400 mg of sulfamethoxazole and 80 mg of trimethoprim (generic for regular-strength Bactrim)
- Sulfamethoxazole/trimethoprim 160/800 mg -- 800 mg of sulfamethoxazole and 160 mg of trimethoprim (generic for Bactrim DS).
Because "sulfamethoxazole/trimethoprim" is such a long name, it is often shortened to "sulfamethoxazole/TMP," especially on prescription labels.
Generic Bactrim is made by several companies, including:
- Teva Pharmaceuticals
- Watson Pharmaceuticals
- URL Pharma.
