Topamax Sexual Side Effects
For those who are taking Topamax, sexual side effects that could occur include impotence, premature ejaculation, and decreased sex drive. Since these sexual problems are common in the general population, however, it is difficult to determine whether they are actually a side effect of Topamax. Sexual side effects should be reported to your healthcare provider immediately so he or she can recommend treatment or adjust your Topamax dosage.
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.
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.
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.
