Once you have an episode of cellulitus and it has been successfully treated with antibiotics you need to stay on antibiotics, usually penicillin 250mg twice a day, as a preventative treatment for 12 months as once you have an episode of cellulitus it is easy for it to re-accur. I got cellulitus in my legs in December 2000 and I am on this preventative antibiotic doseage.
