Some warnings and precautions to be aware of with this drug include:
- Clomid is considered a pregnancy Category X medicine. This means that it is likely to cause harm to an unborn baby. Do not use Clomid if you are or might be pregnant (see Clomid and Pregnancy for more information).
- It is not known if Clomid is passed through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, be sure to talk with your healthcare provider about this.
- Clomid can cause vision changes, including blurred vision or seeing spots. Be aware that these visions changes could affect your ability to drive or operate heavy machinery.

Symptoms of OHSS include abdominal (or stomach) pain or enlargement, upset stomach (nausea), vomiting, diarrhea, and weight gain. If you have these symptoms, contact your healthcare provider right away.
