Levonorgesterel
Category:Morning after PillLevonorgestrel, also known as the "morning after pill," is an emergency contraceptive that is given after unprotected sex to prevent unintended pregnancy.
Levonorgestrel is a hormonal contraceptive pill for women that works by preventing the release of the egg from the ovary to prevent sperm fertilisation (male reproductive cells). Levonorgestrel should be taken within 72 hours of unprotected sex in order to prevent pregnancy; when taken earlier, levonorgestrel is more effective at doing so.

Frequently Asked Questions for Levonorgesterel
How does Levonelle work to prevent unplanned pregnancy?
Levonelle works by either preventing or delaying the release of an egg from the ovary, thereby reducing the chances of fertilization by sperm. The active ingredient in Levonelle mimics the natural hormone progesterone, which is produced in the ovaries. It is crucial to take Levonelle as soon as possible to enhance its effectiveness. Importantly, Levonelle does not interfere with other regular methods of contraception.
How effective is Levonelle at preventing unplanned pregnancy?
The effectiveness of Levonelle decreases with time, so it's crucial to take it as soon as possible after unprotected sex. Here's a breakdown of its effectiveness based on when it is taken:
- Within the first 24 hours: 95% effective
- Within 24 - 48 hours: 85% effective
- Within 48 - 72 hours: 58% effective
After 72 hours have passed since unprotected intercourse, Levonelle may not work at all. It's essential to note that you do not have to wait until the morning after for Levonelle, despite the phrase "morning after pill."
How do I take Levonelle?
Take one Levonelle pill with water as soon as possible.
For maximum effectiveness, Levonelle should be taken promptly after unprotected intercourse.
After 72 hours, the efficacy of Levonelle is uncertain, and the pill may be entirely ineffective. If more than 72 hours have passed, consult your GP for additional contraceptive advice. It's also important to know that Levonelle will not prevent pregnancy if you have unprotected sex after taking it.
Side Effects of Levonelle
Common side effects of Levonelle may include:
- Nausea
- Vomiting
- Abdominal pain
- Breast tenderness
- Fatigue
- Irregular menstrual bleeding
If you vomit or experience diarrhea within 2 hours of taking Levonelle, it may not have been absorbed properly by the gut, potentially compromising its effectiveness. In such cases, seek professional advice from an expert and obtain additional emergency contraception.
