Not as scary as pred, that's for sure! It works good, not great for me, but has really improved quality of life for me. I almost feel normal!
The side effects I get are a mild rash and even more sensitive to the sun, if that's possible! A little achey and nauseated sometimes.
The scariest side effect that held me up was increased risk of lymphoma, but to put it in perspective, another member here on another thread put it like this: Average person has a 1 in 10,000 chance of getting lymphoma; Remicade users have 3 in 10,000 chance. It seems to happen in young adult men more than women, and almost always in conjunction with 6MP medication taken concurrently with the Remicade. Of course, unchecked inflammation can also cause colon cancer in Crohnnies-which incidentally I've had and beat. As with colon cancer, if you get your labs done on Remicade regularly it can prevent most of the more serious side effects.
I've had some pretty bed side effects from prednisone-fractured hips, osteoporosis, severe ulcers and infections, just to name a few...taking Remicade has been worth it for me.
Let's face it-all of us here need scary drugs to stop a scary disease, unfortunately. Hope this helps you make the best choice for you. Best wishes
