if you have isolated the underarm rash to the deodorant then you may have your culprit. hydrocortisone 1% used three times per day would be the recommended treatment for contact dermatitis but it is not a cure-all. sometimes your medical provider will need to prescribed a topical steroid that is stronger.
i have noticed a rash under my arm it is not responding to hydrocortisone cream like it has in the past what should i do. it may have started when i began using a new deodorant however i quit using it when i noticed the rash two weeks ago i have put hydrocortisone cream on it every night and it sort of seemed like it would go away but it has not yet.
