Clomid Side Effects

Clomid side effects and risks vary, with some women experiencing many and others experiencing none at all.

Generally, the side effects of Clomid are said to be fairly mild. Approximately one-third of all Clomid users will develop hostile cervical mucus that kills sperm, making conception nearly impossible. The more nasty side effects of Clomid tend to be associated mainly with higher doses of the fertility drug.

With Clomid generally being the first fertility drug recommended to a woman, its side effects can be very debilitating with severe hot flashes and extreme depression not being uncommon. Very bad mood swings and insomnia are also among the many nasty side effects of Clomid that can occur.

Clomid risks are believed to be few with no known risk of birth defects. There is a risk of Clomid spotting and multiple births, however.
