When working with levonorgestrel, a synthetic progestin used in many birth‑control products. Also known as LNG, it mimics the natural hormone progesterone to prevent pregnancy. levonorgestrel shows up in pills, emergency doses, and intrauterine devices, making it a versatile tool in reproductive health.
One popular format is the combined oral contraceptive, where levonorgestrel pairs with estrogen (usually ethinyl estradiol). This combo, found in brands like Levlen, balances hormone levels to stop ovulation and thin the uterine lining. Users appreciate the daily routine and the added benefits of lighter periods and reduced acne.
Another critical use is emergency contraception, often called the “morning‑after pill.” A single high dose of levonorgestrel taken within 72 hours after unprotected sex can dramatically lower the chance of pregnancy. It works by delaying ovulation and, if fertilization has already happened, may hinder implantation.
Beyond pills, levonorgestrel powers the levonorgestrel‑releasing intrauterine device (IUD). Inserted by a clinician, the IUD releases a steady, low dose for up to five years, offering one of the most effective reversible contraceptive methods available. Users report fewer hormonal side‑effects compared to daily pills because the hormone stays localized in the uterus.
All these formats share common safety considerations. Typical side effects include mild nausea, spotting, or breast tenderness, which usually fade after a few cycles. Women with a history of blood clots, liver disease, or certain cancers should discuss alternatives with a healthcare provider. Because levonorgestrel is hormone‑based, it does not protect against sexually transmitted infections, so condoms remain essential for infection prevention.
