OBJECTIVE: To assess the incidence
of serotonin reuptake inhibitor (SRI) antidepressant-induced sexual
dysfunction (SD) and to compare the sexual side effects of SRI. DESIGN:
Naturalistic, prospective, observational study. SETTING: Two urban
health centers. PATIENTS: 235 outpatients (164 women, 71 males) who
began treatment with some of the following SRI: fluoxetine, sertraline,
paroxetine, citalopram and venlafaxine, who had engaged in regular
sexual practices with stable partner, who were suffering from different
mental disorders who were being treated with SRI. The assignment to each
group was according to clinical criteria. INTERVENTIONS: Patients
completed questionnaires that allowed reporting of both SD induced by
the illness and the treatment, evaluating changes in libido, arousal,
and orgasm. The patients were observed over 6 months of treatment.
RESULTS: 147 patients (62.6%) reported one or more SD related to SRI
treatment. There were differences in the incidence between the different
SRI: 39% with fluoxetine, 75.5% with paroxetine, 78.8% with sertraline,
28.9% with citalopram and 80% with venlafaxine. In 78.2% of patients the
SD showed no improvement by the end of this period. In a predictive
logistical regression model of the presence of SD induced by the SRI,
the female category and the presence of previous sexual problems were
favourable predictors and the treatment with paroxetine, sertraline or
venlafaxine were increased the risk of SD. CONCLUSIONS: SD is one of the
most frequent and persistent SRI adverse effect. We recommended to
inquiry about SD in patients who were treated with SRI. Significant
differences were found in the occurrence of SD between the different
SRI. Such data would be particularly valuable to physicians when
choosing a specific antidepressant from this therapeutic
group.
