Natasha Press, MD, FRCPC (biography and disclosures) What I did before A 32 year old woman, otherwise healthy, presented with a “spider-bite”. It was associated with some surrounding cellulitis but no fever or other systemic features. I recommended incision and drainage, but she wasn’t keen on it, so I gave her a 7-day prescription for cephalexin (keflex) 500 mg po qid. What changed my practice The woman returned to the office 1 week later. The abscess had increased in size and another one had appeared on her labia. She was in significant discomfort and reported no improvement with the cephalexin. Incision and drainage of her abscesses were done, and the culture result from the swab showed community-associated methicillin resistant Staphylococcus aureus (ca-MRSA). This patient did not improve because her abscesses were caused by ca-MRSA which is resistant to cephalexin and other beta-lactam antibiotics. zoloft 25 mg for anxiety Vibramycin (doxycycline) is good for treating many bacterial infections, but can increase your skin's sensitivity to sunlight and make you more likely to get a sunburn or rash.
