My prednisone medication lists psychosis, depression and many other serious afflictions. They are so rare that I feel quite comfortable taking the drug.

Inserts lists all reported side effects and the probability of having one. The problem here is that even if the insert lists something and gives it a 1/10000 chance, you think it's going to happen to you.

With a 1/10000 chance, I wouldn't be afraid to roll the dice. That's the chance of dying while canoeing, by the way.
