Conventional medical wisdom has long held that users of SSRIs are less prone to side-effects than those who use other forms of anti-depressants. But the US researchers say that between 40 and 50 per cent of those taking Prozac and similar anti-depressants, including Zoloft, Paxil, and Luvox, suffer from some sort of sexual dysfunction. "It is now a truth generally acknowledged that SSRIs cause sexual dysfunction more than any other class of anti-depressants," they write.
SSRIs are used by millions around the world. More than 12 million prescriptions are written for them each year in Britain alone.
