Oracea acne antibiotic rash. What cream should I use?

Patient: I was prescribed an acne antibiotic called oracea and it gave me a rash on my arm, neck and crotch. I stopped taking the medicine a week ago yet the rash is continuing to spread. I understand the reaction will continue to do so for a while, but is there any cream I can use to help? It is rather unsightly. I have also been playing basketball which has been irritating it. I need something to put on it. Can it be something something as simple as Johnson Baby Cream or face moisturizer? I’ve been using oil free face moisturizer.

Symptoms: rash
