Sulfa drugs, also known as sulfonamides, are a class of antimicrobial agents used to treat various bacterial infections. However, in order to avoid overuse of this term, it is important to be aware of possible synonyms for this medication. Antibiotics, sulfonamide antibiotics, and anti-infective agents are just some of the terms that can be used interchangeably with sulfonamides. Additionally, trimethoprim-sulfamethoxazole is a combination of two drugs used to treat bacterial infections that can also be referred to as a sulfa drug. Knowing these alternative names for sulfa drugs can help improve communication between healthcare professionals and patients.
