Bactrim DS is not a form of penicillin. It contains sulfamethoxazole and trimethoprim and is a synthetic antibacterial combination product.
However, if you were inquiring about Bactrim being a penicillin because of allergy reasons then people who are allergic to penicillin will most likely be allergic to Bactrim because of the Sulfur group, which they both have. The sulfur is generally the cause of the allergic reactions.
