Q: How often do doctors give cortisone injections to a patient? A: We try to limit the injection to one every three months for any single joint, but also we like to limit it to a total of six injections a year for the whole body. We know that the cortisone can sometimes weaken or suppress the immune system and, in diabetics, it raises blood sugar.
This depends upon the condition and structure in question. With an arthritic joint, there are no specific limitations on cortisone. For example, an arthritic knee can be re-injected as long as it gives reasonable relief. Generally we do not like to give it more often than every few months.
