Question: what antibiotics are used for spider bites?
Answer: Ulcerating lesions should be cleaned daily and debrided as needed; topical antibiotic ointment (eg, polymyxin/bacitracin/neomycin) may be used. Urticarial lesions can be treated with antihistamines, topical corticosteroids, or both. Necrotic lesions caused by brown recluse spider bites should be cleaned and bandaged.
