I haven't been on apriso so I can't comment on that, but I'm currently on Entocort. The side effects haven't been too bad, the only side effect I've experienced is chronic headaches. After 2 weeks of headaches, I called my GI and he put me on Amitriptyline, which cured the headaches and helps me sleep at night (it also supposedly calms the bowels, but I didn't notice a difference there). I think other common side effects of Entocort are things like dizziness and nausea. It's not nearly as bad as other steroids like the dreaded pred. I have been on Entocort for about 2 months now and I haven't gotten moon face and I've only gained about 5 pounds (but I had lost about 20 over the past year so I have been trying to regain some weight anyway). Even before the Amitriptyline I didn't experience any insomnia on Entocort and it doesn't make me feel manic/hyper the way that pred did.
Keep in mind Entocort can take a little while to kick in. It took about 9 days for me to feel a noticeable difference, but I've heard others on here say it can take up to a month. So if it's not working by the time you go back to your doctor, keep an open mind about continuing with it just a little longer. Good luck!
