Did anyone here ever use "Retin-A Micro" for acne?

There may be no validity to this, but I've often wondered. I saw ads a while back about a class action lawsuit against the makers of Accutane since it was possibly a trigger for development of IBD in those who used it.

I'm no chemist, but it looks like the compound for these is somewhat similar.

Accutane: Isotretinoin

Retin-A Micro: Tretinoin

I don't know what the iso- would do.


As a teen I used Retin-A Micro for a few years to treat acne. It would have been roughly 10 years later that I was diagnosed with UC, although symptoms of UC were present maybe 7-8 years later.

I'm not looking to sue whoever made the drug, but I would certainly like to know if it had anything to do with my current UC diagnosis. I am willing to let bygones be bygones but I would at least want to know.


My other theory is that fairly heavy use of Echinacea while in college (didn't want to get sick so I didn't miss class) could have been a culprit. I'm finding less supporting evidence for this theory, though.

I used Retina A, and also Accutane! However it was back in the 70s and there is no way I could ever remember who the doctors were or find those records. So much for a lawsuit.

Yep. Cream.

I used Retin-A as well as in my teens. But IBD is in my family. And my sibling who used both Retin-A and Accutane doesn't have IBD.

I used retin A and Echinacea
