ABSTRACT
BACKGROUND: In psychotic disorders, early intervention with antipsychotic medications increases the likelihood of favourable long-term course. However, the pharmacologic management especially with conventional antipsychotic medications is complicated by a high rate of adverse effects including sexual dysfunction. This study aims to determine the demographic and clinical factors associated with sexual dysfunction among male psychiatric outpatients on conventional antipsychotic medications in South-western Nigeria. METHODS: Two hundred and seventy five consecutive male outpatients with psychotic disorders on conventional antipsychotic medications were interviewed. Data was collected on demographic characteristics, illness-related and medication-related variables. Illness severity was assessed with the Brief psychiatric rating scale. The International Index of Erectile Function questionnaire was used to assess for sexual dysfunctions. RESULTS: A total of 111 (40.4%) respondents had one or more forms of sexual dysfunction. Sexual desire dysfunction was present in 47 (17.1%) of respondents, erectile dysfunction in 95 (34.5%), orgasmic dysfunctions in 51 (18.5%), intercourse dissatisfaction in 72 (26.2%) and overall dissatisfaction in 64 (23.3%). Sexual dysfunction was significantly associated with employment status, age, marital status, haloperidol use, medication dosage, and presence of psychopathology. Unemployment was the only significant independent correlate of sexual dysfunction, with unemployed respondents twice more likely to have sexual dysfunction compared with those employed (Wald = 3.865, Odds Ratio = 2.033, 95% confidence interval = 1.002 - 4.124, p = 0.049). CONCLUSIONS: The high prevalence of sexual dysfunction found in this study suggests a need among clinicians for increased awareness and recognition of the sexual side effects in patients taking conventional antipsychotic medications. This knowledge should guide conventional antipsychotic medication prescription in the at-risk population to improve treatment adherence.
