Loestrin 24 contains a combination of ethinyl estradiol and norethindrone acetate. Ethinyl estradiol is a synthetic estrogen that mimics the effects of the naturally occurring hormone, estrogen. Norethindrone acetate is a synthetic progestin, similar to progesterone, another naturally occurring hormone. These hormones work together to prevent pregnancy primarily by suppressing ovulation.
How Loestrin 24 Works
Ethinyl estradiol helps to thicken cervical mucus, making it harder for sperm to reach the egg. It also plays a role in suppressing follicle-stimulating hormone (FSH) and luteinizing hormone (LH), thereby preventing the release of an egg from the ovary (ovulation). Norethindrone acetate further inhibits ovulation and alters the uterine lining, making it less receptive to a fertilized egg. The combined effect of these hormones results in highly effective contraception.
Important Considerations
Remember, Loestrin 24, like all hormonal contraceptives, may cause side effects. These can vary from person to person and include changes in menstrual bleeding patterns, weight fluctuations, mood changes, and breast tenderness. Consult your healthcare provider if you experience any concerning side effects or have questions about Loestrin 24’s suitability for you. They can provide personalized advice and address any concerns.
