There’s the Rub: a narrative review of the benefits and complications associated with Vicks VapoRub use
Abstract
Background Vicks VapoRub (VVR) is a globally popular over-the-counter remedy marketed for use as a topical antitussive and analgesic. This review seeks to provide health professionals and care providers with a thorough summary of the benefits and complications associated with VVR use reported in the medical literature, identify off-label consumer behaviors that might increase the risk of health complications, and encourage further research into over-the-counter (OTC) medications. Methods Three databases—PubMed, Web of Science, and Embase—aided in creating a pool of 220 studies. For inclusion, studies had to discuss the therapeutic application of VVR in humans or a complication arising from its use. Findings Thirty-seven articles were found to meet inclusion criteria. Nine synthesis groups were created: three groups concern the product’s efficacy in regard to upper respiratory tract infection (URTI) symptom treatment (n = 7), onychomycosis treatment (n = 2), and in the context of wound care (n = 2). Six groups collate case reports that describe VVR-related complications, including VVR-associated lipid pneumonia (n = 11), ocular injury (n = 5), camphor toxicity (n = 5), dermatological conditions (n = 3), psychosis (n = 1), and respiratory distress (n = 1). The evidence around the use of VVR for the treatment of URTI symptoms and onychomycosis is limited and inconclusive. Even more limited cross-sectional data concerns its use in wound care. Many of the complications described…
