I appreciated the pertinent article by Dr. Burghardt and Ms. Gardner, “Sildenafil for SSRI-induced sexual dysfunction in women” (Current Psychiatry, April 2013, p. 29-32; http://bit.ly/1GCtLZR). Evidence for alternative adjunctive medications for selective serotonin reuptake inhibitor (SSRI)-induced sexual dysfunction is lacking.
There is some support for bethanechol in reversing dysfunction caused by other antidepressants. Bethanechol reversed anorgasmia in a woman receiving amoxapine and eliminated erectile dysfunction in men receiving monoamine oxidase inhibitors or tricyclic antidepressants.1-3 The only trial evaluating the efficacy of bethanechol for antidepressant-induced sexual dysfunction found it effective for men receiving clomipramine.4 Evidence is limited to patients receiving older antidepressants, and there is only 1 report of efficacy in a female patient.
It would be interesting to see whether bethanechol is effective for SSRI-induced dysfunction in controlled trials, because it may be a practical option for patients with sexual dysfunction and urinary retention.
