Which antibiotic is commonly used to treat MRSA skin infections?

• A. Clindamycin
• B. Doxycycline
• C. Amoxicillin
• D. TMP-SMX

Answer: (D)

MRSA skin infections require antibiotics with reliable activity against MRSA. TMP-SMX provides strong coverage against community-associated MRSA strains and is effective for uncomplicated skin and soft tissue infections when given orally. It is convenient for outpatient treatment and generally well tolerated. Amoxicillin is often ineffective against MRSA due to beta-lactam resistance, while clindamycin and doxycycline can be used in some cases but have issues with resistance or tolerability; therefore TMP-SMX is a common first-line choice for MRSA skin infections.
