Association between the use of serotonin receptor 2A-blocking antidepressants and joint disorders.

Objective: There are case reports about antidepressants causing arthritis and arthralgia, and the majority of these reports deal with atypical antidepressants, which are serotonin receptor 2A (5-HT(2A))-blocking substances.
