Doctors are already cautious about using glucosteroids due to their lengthly list of frequent, serious side effects. This caution should continue. The risk of clots is the highest after beginning a new steroid regimen. The risk continues throughout the steroid use and then for at least a year after the steroid is discontinued.
The important thing to learn from this study is that every patient needs to discuss this risk with his or her doctor. It would be a good idea to discuss the risk of the steroid, other risks that the patient has, and possible ways to lower the risk of clotting.
