However, not all women are able to get pregnant even though these drugs are used. Drugs used include clomiphene citrate, bromocriptine, gonadotropins, and gonadotropin-releasing hormone. Some of these are taken as tablets while others are given as shots. Clomiphene is used mostly in women with near normal ovaries and normal female hormone levels. This drug can usually make 80 percent of these women ovulate and half of those will get pregnant when using clomiphene.
Twins are slightly more common when pregnancy is assisted with clomiphene.
The side affects of clomiphene include hot flashes, nausea, breast tenderness, and rarely, vision changes. Bromocriptine is used in a specific group of women that have a high prolactin level. Prolactin is a hormone secreted by the brain. Bromocriptine returns the pregnancy rate to normal in these women. The side effects can be headache, upset stomach, light-headedness, and a stuffy nose.
