Topamax Sexual Side Effects: An Overview
Topamax® (
topiramate) is known to cause certain sexual side effects. Topamax sexual side effects may include:
Decreased Sex Drive
Topamax is known to cause a decrease in sex drive (known as libido). In clinical studies where side
effects of Topamax were documented, a decreased sex drive occurred in up to 3 percent of people taking Topamax for
seizures and up to 2 percent of people taking
Topamax for migraine prevention.
Premature Ejaculation
Topamax is also known to cause premature ejaculation in men. Premature ejaculation is when a man uncontrollably ejaculates too soon (either before or just after sexual penetration). In clinical studies where side effects of Topamax were documented, premature ejaculation occurred in up to 3 percent of men taking Topamax for
migraines. Premature ejaculation was not reported in men taking
Topamax for epilepsy.
Impotence
Topamax is known to cause impotence in men. Impotence is often defined as a total inability to achieve erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. Ultimately, impotence is the repeated inability to get or keep an erection firm enough for sexual intercourse. In clinical studies where side effects of Topamax were documented, impotence occurred in 1 percent of men taking Topamax for
epilepsy, although the exact percentage was not reported. Impotence was not reported in men taking Topamax for
migraine prevention.
