Increased sexual function after intake of clomethiazole.

An octogenarian woman showed increased sexual function after replacing alprazolam with clomethiazole, a sedative-hypnotic drug commonly prescribed in French-speaking Switzerland for the treatment of anxiety and insomnia in elderly patients. The patient's sexual symptoms did not improve after resuming alprazolam, but disappeared after interrupting clomethiazole, and did not reappear when alprazolam was discontinued. Considering the chronology of the events, increased sexual function was likely a manifestation of the introduction of clomethiazole. However, because alprazolam was interrupted when clomethiazole was introduced, we cannot exclude an association between increased sexual function and alprazolam interruption.
