is possible to develop a physiological dependence upon steroids. Taking steroid drugs affects the functioning and hormone secretion pattern of the adrenal glands, since these glands are the source of many natural steroid hormones. For this reason, when doctors prescribe steroids, their discontinuation is always tapered (gradually taking smaller doses) to allow the adrenal glands to return to their normal pattern of function and secretion. Likewise, abrupt discontinuation of anabolic steroid use can also result in withdrawal symptoms that can be dangerous and even potentially fatal.
Most modern steroid enemas are foam based - as the likelihood of someone with colitis being able to retain a water based enema is quite low. These act topically applying the steroid directly to the colon - with only small amounts being absorbed into the bloodstream. This makes side effects less likely. The downside is that they can only reach the descending colon and rectum - so for those with extensive colitis oral steroids may be needed. A combination of Entocort and steroid enemas can provide topical treatment to the majority of the colon - again minimizing side effects. As the two main steroid enemas differ quite greatly I will cover them separately.
