PainSci summary of Reurink 2014?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided at the bottom of the page, as often as possible. ★★★☆☆?3-star ratings are for typical studies with no more (or less) than the usual common problems. Ratings are a highly subjective opinion, and subject to revision at any time. If you think this paper has been incorrectly rated, please let me know.
Injecting medications into muscles might not be harmless. (No one’s surprised by that, right? Good.) This data shows that anaesthetics and NSAIDs are myotoxic, and there’s “conflicting evidence” about PRP (which is generally still understudied). Corticosteroids get an all clear … unless you use it with anaesthetics, which isn’t uncommon.

BACKGROUND: Injection therapies are widely used for muscle injuries. As there is only limited evidence of their efficacy, physicians should be aware of the potential harmful effects of these injected preparations.
OBJECTIVES: The purpose of this review was to systematically review the literature on the myotoxic effects of intramuscular injection preparations commonly used for acute muscle injuries.
DATA SOURCES: The databases of PubMed, Embase, Web of Science, Cochrane Library, CINAHL and SportDiscus were searched in March 2013.
STUDY ELIGIBILITY CRITERIA: Studies reporting histological evaluation or creatine kinase activity after intramuscular injection with local anaesthetics, corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs), platelet-rich plasma (PRP), Traumeel(®) and Actovegin(®), or combination preparations were eligible for inclusion.
DATA ANALYSIS: Two authors independently screened the search results and assessed the risk of bias. A best-evidence synthesis was used to identify the level of evidence.
RESULTS: Forty-nine studies were included in this systematic review. There is strong to moderate evidence that intramuscularly injected local anaesthetics and NSAIDs are myotoxic, and there is conflicting evidence of the myotoxicity of PRP. There is limited evidence that single corticosteroid injections are not myotoxic but have a synergistic myotoxic effect when used together with local anaesthetics. There is no information to assess whether Actovegin(®) and Traumeel(®) are myotoxic.
CONCLUSION: Local anaesthetics and NSAID injections are not recommended for the treatment of muscle injuries in athletes, as they are myotoxic. The possible myotoxic effects of corticosteroids, PRP, Traumeel(®) and Actovegin(®) should be assessed in future research.
