Bactrim DS Tablet (Trimethoprim and Sulfamethoxazole) may sometimes be prescribed for acne, but it is usually not the first choice and should be continued only if advised by your doctor. Scalp acne may also be due to folliculitis (inflammation or infection of hair follicles), which may require a different treatment, such as topical lotions or medicated shampoos. Please consult your doctor to review the diagnosis and decide whether to continue or change the medication.

If a patient has a known allergy to sulfa drugs, they should avoid taking Bactrim DS (Sulfamethoxazole + Trimethoprim), as it contains a sulfonamide antibiotic that can trigger allergic reactions ranging from mild skin rashes to severe reactions like Stevens-Johnson syndrome; even if previous responses were mild, caution is strongly advised, and a healthcare provider should be consulted to consider safer alternative antibiotics.
