Corticosteroid medicine. Do not stop using Prednisolone suddenly, or you could have unpleasant withdrawal symptoms. Prednisolone is a synthetic corticosteroid which is often simply called steroid, but it should be noted that it is very different from another group of steroids, called anabolic steroids, which have gained notoriety because of their abuse by some athletes and body builders. Steroid medication needs may change if you have a fungal infection anywhere in your body.
