Levonorgestrel BP: Uses, Safety, and How It Works
When you hear about levonorgestrel BP, a synthetic progestogen listed in the British Pharmacopoeia and widely used for birth control. Also known as levonorgestrel (BP grade), it works by binding to the progesterone receptor, the cellular target that regulates the menstrual cycle and implantation. This binding blocks ovulation and thickens cervical mucus, which is why the drug is a core component of emergency contraception, a high‑dose, time‑sensitive method to prevent pregnancy after unprotected sex. In practical terms, a single 1.5 mg dose taken within 72 hours can reduce pregnancy risk by up to 85 %. The same molecule also appears in many hormonal contraceptive pills, often combined with estrogen to create a daily regimen that stabilizes hormone levels. Understanding these relationships helps you see why levonorgestrel BP is both a rescue option and a regular birth‑control ingredient.
Key Considerations for Levonorgestrel BP Users
Levonorgestrel BP’s effectiveness hinges on timing and dosage. For emergency use, the drug must be taken as soon as possible; each hour that passes slightly lowers its protective power. Side effects are generally mild—nausea, fatigue, or slight spotting—but they signal the hormone’s action on the uterine lining. When combined with estrogen in daily pills, levonorgestrel BP contributes to cycle regulation, reducing acne and menstrual cramps. It also interacts with other medications that affect liver enzymes, so a quick check with a pharmacist can prevent unwanted interactions. The molecule’s chemical stability, guaranteed by its BP specification, ensures consistent potency across brands, making it a reliable choice for clinicians and patients alike.
