Which of the following medications should be avoided by patients allergic to sulfa drugs?

B. Keflex
C. Ceftin
D. Bactrim
A. Biaxin

The correct answer is: A. Biaxin

Patients allergic to sulfa drugs should avoid taking medications that contain sulfonamides, as this can lead to an allergic reaction. Biaxin (clarithromycin) does not contain a sulfonamide moiety and is safe for patients allergic to sulfa drugs. Options A, B, and C (Keflex, Ceftin, Bactrim) contain sulfonamides and should be avoided by patients with sulfa drug allergies.
