Trimethoprim/sulfamethoxazole (Bactrim, Bactrim DS)

Outpatient therapy

For non-severe MRSA infections.

Trimethoprim: Inhibits dihydrofolate reductase, thereby blocking production of tetrahydrofolic acid from dihydrofolic acid.

Sulfamethoxazole: Inhibits bacterial synthesis of dihydrofolic acid by competing with para­aminobenzoic acid.

Caution: Pregnancy category D. Medication crosses into breast milk. Avoid use in breastfeeding mother if nursing preterm infants, infants <2 months, or children with known or suspected glucose-6-phosphate dehydrogenase (G6PD) deficiency.
