Sexual function is important for patients’ well-being but it is a common side effect of SSRI and SNRI, included desvenlafaxine.
Evaluate incidence and characteristics of sexual dysfunction caused by desvenlafaxine in the clinical practice.
One hundred and thirty-three patients with recently introduced desvenlafaxine treatment are recruited from Barakldo and Uribe-Kosta Mental Health Centres in Biscay, Spain. UKU scale is administered to measure sexual side effects. Statistical analysis is performed using SPSS v.22.
Sexual dysfunction is observed in 5 patients (3.7%) at 50 and 100 mg/d (2 and 3 patients, respectively) desvenlafaxine doses. Two patients (1.5%) have experimented more than one sexual side effect. Regarding gender differences, the most frequent sexual dysfunctions are diminished sexual desire (5.5%) and erectile dysfunction (5.5%) in men and orgasmic dysfunction (1.2%) in women (P-values are 0.034; 0.034 and 0.408, respectively). Discontinuation is decided in 60% of patients.
Desvenlafaxine has a well-tolerated sexual side effect profile in general population. There are some gender-related differences both in presentation and perception, as it has been described with other drugs, and this should be taken into account by prescriptors.
