What are the side effects of the birth control pill Blisovi Fe?

Blisovi Fe is a hormonal combination birth control pill containing a progestin (norethindrone acetate), an estrogen (ethinyl estradiol), and an iron supplement (ferrous fumarate). Blisovi Fe is a generic version of the brand-name medication Loestrin Fe. It comes in several different strengths, including Blisovi Fe 1/20, Blisovi Fe 1.5/30, and Blisovi 24 Fe. In addition to being used as a contraceptive, Blisovi Fe can be used to regulate menstrual periods and decrease the risk of ovarian cysts. Blisovi Fe does not protect against sexually transmitted diseases such as HIV.

While this medication is generally well tolerated, it may cause some side effects. The most common side effects of Blisovi Fe include nausea, vomiting, stomach pain or cramps, bloating, breakthrough bleeding, or irregular menstrual cycles. Although not common, it may also cause more serious side effects, including an increased risk of blood clots, stroke, and other heart problems. This risk is further increased if you are over 35 years of age and smoke.

What does Blisovi Fe do?

Blisovi Fe contains 2 hormones, norethindrone acetate and ethinyl estradiol, which work together to stop you from becoming pregnant. It does this by preventing your ovaries from releasing eggs (ovulation). It also causes changes in your cervical mucus, which makes it difficult for sperm to get into the womb (uterus). Finally, it changes the lining of your uterus so that a fertilized egg has a hard time attaching to the womb.
