So weeks ago I got horrible breakouts on my shoulders from using my backpack. I applied Tazorac to make the acne go away/prevent scarring and I've been applying Tazorac to the areas ever since to make the remaining redness go away. Well, several days ago, I woke up in the morning and those same areas looked like a rash and were very itchy. Also, I saw that I had light-red marks (rash?) all under my underarms. For months now I've been applying Tazorac to some stretch marks located near my underarms... it's the area on my torso, right before my chest reaches my underarm, yet it's not under my arm.

Well those areas were super itchy and I couldn't sleep. Since then I've stopped applying Taz to those areas and have instead been applying Hydrocoritsone for the insane itching. Now, the redness under my arms is fading (still itches, not as much), the itching has gone from my shoulder areas, but now yesterday an itch developed on my anus, and today it's more so on the sides of my scrotum.

This rash/itch could be a result of something else, yes, but one theory of mine is that using too much Taz on the body caused a reaction. So, I'm wondering, has this happened to anyone else? Or do you know what this bodily itch is? Thank you.

I've been using Tazorac for years, mate, had no problems like yours. No problems at all, in fact. Dunno what's going on with you.

It just recently all went away, but after eating breakfast today, I noticed my underarms were itching a little and I looked, and they are starting to get red again. I applied hydrocortisone so hopefully I can catch them before they get worse. Maybe I'm still using too much Taz on my chest? As opposed to liberally putting it on big areas before, I've just been applying a little on a couple new zits, and yet the red is back. Probably a good idea to see a doctor sometime soon...

It happened to me and I think my derm said it was dermatitis of some variation. Anyways he gave me this clobex spray and after awhile the rash goes away and i can still apply the tazorac. It generally occurs when I start tazorac up againt after awhile.
