Hi,
I'm on Tazorac--just switched from retin-a. It's supposed to be stronger than retin-a, at least that's what my derm said. I guess it takes time. I can't really give you advice on how well it works bc I'm pms, and it's spring-and for some reason, I always break-out in Spring.
I did try it before, and it was awesome!! It made my usually oily skin, perfectly balanced. They were samples-1%, but now I have .5%, and I need to go back to 1% since it worked better. (They give me samples, and they only had 5% on hand.)
I used to take Dynacin, which worked wonders, but ran out, and it's really expensive, so now they have me on Doryx(doxy). Unfortunately, I have to pay for meds, so I rely on them giving me samples, and sometimes they don't have what is best for me.
Once you come off the bactrim, you should ask for Dynacin(mino), it's good.
Good Luck.
