No side effects or progress so far. I've been on them for about 2.5 weeks now, so way too early.
I am still moisturizing and helping some build off at times. I'll be continuing that way for a while. If I don't get any improvement in the next few months I might think about it, but until then I don't think that the way I'm handling my lips now should have all that much of an effect if the medications in fact do help.
