There is currently a generic version of Sulfatrim available, sold under the name sulfamethoxazole/trimethoprim suspension (or sulfamethoxazole/TMP). The FDA has assigned generic Sulfatrim products an "AB" rating, meaning that the generics are equivalent to the brand-name medication. However, the generic versions may have different inactive ingredients (such as fillers or dyes) that may cause problems for some people.

Generic Sulfatrim: An Overview

Sulfatrim® (sulfamethoxazole/trimethoprim) is a prescription antibiotic medication. It contains sulfamethoxazole (a sulfonamide, or "sulfa" antibiotic) and trimethoprim (another antibiotic that helps to increase the effectiveness of sulfamethoxazole).
Brand-name Sulfatrim was manufactured by Actavis US but is no longer available. However, the generic form is still available.

Strengths of Generic Sulfatrim

Generic Sulfatrim is available in one strength -- sulfamethoxazole/trimethoprim suspension, with 200 mg of sulfamethoxazole and 40 mg of trimethoprim per teaspoonful (per 5 mL).
Because "sulfamethoxazole/trimethoprim" is such a long name, it is often shortened to "sulfamethoxazole/TMP," especially on prescription labels.

Who Makes the Generic Version of Sulfatrim?

The generic version of this medicine is made by the following companies:
  • Hi-Tech Pharmaceuticals
  • Teva Pharmaceuticals.

Is Generic Sulfamethoxazole/Trimethoprim as Good as Sulfatrim?

All generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medication, and assigns each generic a rating. An "AB" rating means the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic sulfamethoxazole/trimethoprim suspension versions currently available have an "AB" rating, meaning they should be equivalent to Sulfatrim.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients that may cause problems for people with allergies or sensitivities.
