Haloperidol decanoate (Janssen) in the treatment of sexual deviations.

Haloperidol decanoate inj. (Janssen) á 150 mg was evaluated during long-term (max. 4.2 years) treatment of 30 sexual offenders. We proved that the drug was well tolerated also by non-psychotic patients by using of low doses (37.5 mg) with intervals between injections 6 weeks. Extrapyramidal side effects were on minimal level. "Side" effect on sexual functions and appetence turned to be the main effect of the drug. The influence on sexual reactivity was objectively examined by electrocapacitative phalloplethysmograph (Figar). There were detected the latency of initial phase of the PPG curve and prolongation of the incremental slope. The decremental slope of the PPG curve was shorter.
