The typical treatment duration for erysipelas is 10 to 14 days. If it is the first outbreak of erysipelas and the treatment is not timely or thorough, or if the treatment duration is insufficient, it is very susceptible to recurrent erysipelas. Treatment for recurrent erysipelas is more challenging, and it may take about three weeks for some people to recover. Especially in elderly patients with swelling in the lower limbs, it is difficult to completely reduce the swelling, which can lead to long-term conditions like elephantiasis. No matter how long any medication is administered, it cannot be completely eliminated, so it is crucial to start treatment gradually and by courses at the onset of the disease. Penicillin is the first choice of medication. For patients allergic to penicillin, cephalosporins or macrolide drugs are the alternatives.
