Abstract
Our purpose was to determine if oral cimetidine, a histamine‐receptor antagonist, might be of benefit in the treatment of extensive molluseum contagiosum in children. We present 13 pediatric patients in whom conventional treatment modalities for molluseum contagiosum were unsuccessful or difficult to apply. They were treated with a two‐month course of oral cimetidine 40 mg/kg/day. All but three children who completed treatment experienced clearance of all lesions. These children had no new lesions but had persistance of several lesions. One child did not take the drug and did not clear. No adverse effects were observed. We conclude that oral cimetidine may be of benefit in the management of widespread or facial molluseum contagiosum in immunocompetent children.
