My son is 3 yrs. old, diagnosed by my dermatologist with eczema. He's got eczema all over his body.He was prescribed with Clobetasol Propionate Ointment USP, 0.05%... I read on the Pediatric Precaution that "It's not recommended for children under 12... How safe is this medicine... should I stop giving it when it specifically said "Not recommended for children under 12"... Pls. help...
