All rapid responses
Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles or when it is brought to our attention that a response spreads misinformation.
From March 2022, the word limit for rapid responses will be 600 words not including references and author details. We will no longer post responses that exceed this limit.
The word limit for letters selected from posted responses remains 300 words.
We read with interest your editorial 'Post SSRI Sexual dysfunction' (1). The commonly reported side effects with these widely prescribed first line drugs are headache, drowsiness, weight gain, sexual dysfunction and gastrointestinal symptoms.
We would like to take this opportunity to alert your readership to a less commonly recognised phenomenon of SSRI associated bruxism and jaw pain. We see a significant proportion of patients presenting to the Maxillofacial department with Temporomandibular joint disorder and bruxism associated with SSRI use. The literature suggests an association with serotonergic antidepressants (SSRI and SNRI) inducing jaw pain/jaw spasm reversible syndrome (2). The patient presents with jaw pain, teeth grinding and trismus commonly within a month of starting drug therapy or a dose change and which can resolve within 4 weeks of cessation of the medication.
We commonly come across patients on Citalopram, Fluoxetine, Sertraline, and Venlafaxine displaying side effects of bruxism. Apart from discontinuation of the drug there is reported role of Buspirone as an antidote for this side effect. Bruxism is now included as an adverse drug reaction in the product information of Paroxetine containing products following the decision of the CMDh (3). Colleagues in primary care managing these patients should be aware of this little known yet significant side effect of SSRI antidepressants.
