From the Research
The recommended waiting period between steroid injections is at least 3-4 months, as supported by the most recent and highest quality study 1. This study, published in 2019, found that repeat administration of triamcinolone acetonide extended-release using a flexible dosing schedule timed to patient response was well tolerated, with no radiographic evidence of cartilage impact. The study also found that the magnitude and duration of clinical benefit after the first and second injections were similar, and most patients reported a substantial (≥ 50%) analgesic response after both doses. Key points to consider when determining the waiting period between steroid injections include:
- The specific condition being treated and the injection site
- The type of steroid used and the dose
- The patient's individual medical history and response to previous injections
- The potential risks of frequent steroid injections, such as tissue damage, weakening of tendons and ligaments, cartilage deterioration, and systemic side effects like elevated blood sugar, mood changes, and adrenal suppression. Other studies, such as 2 and 3, also support the use of steroid injections for osteoarthritis pain, but the study by 1 provides the most recent and highest quality evidence for the recommended waiting period. It is essential to follow the healthcare provider's specific recommendations, as they will consider the individual patient's needs and circumstances when determining the appropriate interval between steroid injections.
