My acne medication makes my face itchy. should i discontinue using it and switch to something else?

Your choice: You have several different topical options, but if you're using either topical benzoyl peroxide or a retinoic acid derivative or salicylic acid, see if you can't tolerate the itching; it's good to use these r'x as tolerated and go on to prescription rx only if you really need to. Or you can try reducing the frequency of application.
