What is the minimum interval between intra-articular glucocorticoid injections to minimize adverse events?

• A. At least 6 weeks
• B. At least 1 month
• C. At least 3 months
• D. At least 6 months

Answer: (C)

The main idea is that tissues need time to recover between injections of glucocorticoids into a joint, because repeated exposure can raise the risk of adverse effects such as cartilage damage, tendon or soft tissue weakening, and local skin changes. Waiting three months between injections gives the joint time to recover from each dose and reduces cumulative exposure to the steroid, which lowers the chance of harming the cartilage and surrounding structures. Shorter intervals, like six weeks or one month, increase the likelihood of these adverse events, while waiting much longer than necessary isn’t required for safety and could delay symptom relief. Therefore, spacing injections by at least three months is the best balance to minimize adverse events.
