You can still use drugstore products for the regimen. Just check that it's a 'suitable' cleanser - so something that is non-medicated (no BP, salicylic acid, other acne fighting ingredients in it). You can check the info on drugstore products for the regimen here http://www.acne.org/regimen (go down to 'products you need' and click 'drugstore alternatives')

It shouldn't cause any trouble switching cleansers unless there's something in the new cleanser your skin doesn't like
