Although most people do not experience any problems while taking prednisone, side effects are possible. However, side effects of the medicine are typically minor and, in most cases, either do not require medical attention or can be treated easily.
Potential side effects of prednisone include mood changes, insomnia, stomach irritation, and headaches. These are the problems that have been reported with short-term use of the drug.
Any potential prednisone dangers are usually related to long-term use of the medication. Taking the drug for long periods of time can cause osteoporosis, cataracts, loss of muscle, or fat deposits on the face and back.
Other rare but possible prednisone problems include infections, blood in the stool (a sign of gastrointestinal bleeding or ulcers), hallucinations, and hives or itching (signs of an allergic reaction).
