Question: what antibiotic to treat mastitis?
Answer: Mastitis typically responds to antibiotic treatment within 24 hours. Your doctor may prescribe the antibiotic dicloxacillin. If you're allergic to penicillin, alternatives include erythromycin (Ery-Tab) or clindamycin (Cleocin). Also, you can clear the infection faster with continued breast-feeding or pumping.
