I took Accutane, but after I had Type 1 diabetes. I thought the drugs which are associated with diabetes, such as some psychiatric medications, caused metabolic changes resulting in Type 2 diabetes, not Type 1. It is not clear by this statement whether Type 1 is actually be referred to or not.
I can say that Accutane changed my life, for the better. I took it after suffering from acne for 15 years, and really wish I had taken it earlier .
I think you are right to be wary of the anecdotal stuff you read on the internet. Really a good way to get frothed up. I was convinced that I got Type 1 from a flu sot after reading stuff online.....then I realized I had gotten the flu shot after. Not that anecdotal evidence can't be true, but it at times isn't accurate. For a while there was a presumed connection with accutane and suicide, brought to light after a senator's son committed suicide after using accutane. Not sure if anything was ever found of that.
I will say that I will be following this and hope there is more research before my kids are older, because if they are like me, acne will become the bane of their existence in the future, but I would not want them to take it if it were associated with autoimmune issues!
