Summary
Scarlet fever is treated with antibiotics to kill group A streptococcus bacteria.
These antibiotics may include cephalexin, cefadroxil, clindamycin, azithromycin, or clarithromycin.
Home remedies and OTC medications are not a substitute for antibiotics.
However, they can help relieve symptoms while you’re finishing your prescription medication.
For an itchy rash, try an oatmeal bath or OTC cortisone or calamine lotion.
