Antidepressant-induced sexual dysfunction is a common, troublesome complication of antidepressant treatment that patients often fail to report, which can have major consequences, including non-adherence to treatment with resultant relapse of depressive illness. The aim of this paper is to review the extent, causation and evidence-based management of antidepressant-induced sexual dysfunction to inform clinical practice. ⋯ The preponderance of evidence suggests that antidepressant s can be divided into high risk (selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants, monoamine oxidase inhibitors) and low risk (agomelatine, bupropion, moclobemide and reboxetine) categories with regard to propensity for antidepressant-induced sexual dysfunction, although there is disagreement, particularly about mirtazapine, and methodological issues militate against definitive findings. Antidepressant-induced sexual dysfunction is dose-dependent to an extent, but patient vulnerability factors are also relevant. There are significant differences in antidepressant-induced sexual dysfunction between men and women. It is important to ask antidepressant -treated patients about sexual dysfunction as few self-report; this may well contribute to antidepressant non-adherence. Consider using an antidepressant with low risk of antidepressant-induced sexual dysfunction for initial treatment. When antidepressant-induced sexual dysfunction has developed, try to persuade the patient to wait in case tolerance develops. Then consider changing to a lower risk or use of high/low risk antidepressant combinations but pharmacological expertise is required. Adjunctive sildenafil can help in both sexes.

Case ReportsPaliperidone: another treatment option for delusional parasitosis.
Patients with delusional parasitosis (DP) have a fixed belief of being infested by small pathogens. Typical and atypical antipsychotics are widely used for treating DP. There are limited controlled trials about the treatment of DP and the most useful antipsychotic agent is still unknown. Paliperidone treatment for DP will be demonstrated through two cases. One of these cases had previously used pimozide but had not responded to treatment. Both cases had remission from symptoms with paliperidone. There are only two case reports published about paliperidone treatment for DP. ⋯ Paliperidone appears to have promise in the treatment of DP; however, more case reports and controlled trials are required.
