Are you positive it is acne and not a rash? Getting a rash right after starting a new med can indicate an allergy and signal you should stop the med right away.. Please be careful. If your pdoc can't see you soon, can you go see your regular doctor for help with the acne? He/she could also diagnose if it might be a rash if you are uncertain.

For acne, I think you want a lotion that is drying, not moisturizing. You can also ask the pharmacist for advice on over the counter remedies.
