Hi all, DS (8 months) has had diarrhoea over the weekend and now has hideous nappy rash, blistering skin etc. Been to GP who prescribed 1% HC cream to be used aparingly once or twice per day. However it says in the leaflet NOT to use under a nappy as it can cause too much HC to be absorbed and affect adrenal gland. Surely they wouldn't prescribe it if not needed/correct??
