Article Abstract

Background:Current literature suggests that the incidence of sexual dysfunction secondary to fluvoxamine therapy is 1% to 8%, while other selective serotonin reuptake inhibitors may have rates as high as 75%. The objective of this study was to determine the incidence of sexual dysfunction secondary to fluvoxamine in healthy volunteers.

Method:20 healthy volunteers (10 men, 10 premenopausal women) had adverse effects assessed at 6 visits while not receiving fluvoxamine, then twice while taking 150 mg fluvoxamine daily. Assessments occurred at 2-week intervals. Incidence rates for sexual dysfunction were calculated.

Results:No sexual dysfunction was reported prior to fluvoxamine therapy. After 2 weeks and 4 weeks of therapy respectively, sexual dysfunction occurred in 20% (N = 4) and 35% (N = 7) of the healthy volunteers.

Conclusion: The incidence of sexual dysfunction during fluvoxamine therapy in healthy volunteers is 35%. This incidence is higher than previously reported and similar to that of other selective serotonin reuptake inhibitors.
