The side effects of clomiphene citrate capsule are as follows: i. If ovulation promotion is performed with the drug without the corresponding examination, it may lead to ovarian overstimulation and cause corresponding symptoms, such as ascites, urine reduction, abdominal distension, abdominal pain, dizziness and other corresponding symptoms, which should be actively given. Secondly, clomiphene will cause the local mucus of the cervix to thicken after taking it, so although the success rate of ovulation promotion is relatively high, which can reach about 75%, the chance of pregnancy has decreased, mainly because the thickening of the mucus of the cervix prevents sperm from passing through the cervix, so this is the second side effect. Thirdly, it may lead to ovarian function decline, so clomiphene should be used carefully in clinical practice to promote ovulation, and the drug should be used only after a thorough evaluation before ovulation promotion.
