Levonorgestrel is a hormone used in many types of birth control pills and emergency contraception. It is a popular contraceptive option, but like any medication, it can have side effects and potential risks. In this post, we will answer some of the most frequently asked questions about levonorgestrel and its side effects. It’s important to note that this is not medical advice and you should always speak with your healthcare provider about your specific needs and concerns.
What is levonorgestrel?
Levonorgestrel is a synthetic hormone that is similar to progesterone, a naturally occurring hormone in the female body. It is used in birth control pills to prevent pregnancy and in emergency contraception, also known as the “morning after pill.” Levonorgestrel can be taken orally or inserted into the uterus as an intrauterine device (IUD).
How does levonorgestrel work?
In birth control pills, levonorgestrel works by preventing the release of an egg from the ovary and thickening the cervical mucus, which makes it harder for sperm to reach the egg. In emergency contraception, levonorgestrel can prevent pregnancy by inhibiting or delaying ovulation, or the release of an egg from the ovary.
What are the common side effects of levonorgestrel?
The most common side effects of levonorgestrel-containing birth control pills are:
- Nausea
- Breast tenderness
- Irregular bleeding or spotting
- Headaches
Most of these side effects are temporary and should improve after a few months of taking the pill. If they persist or are severe, you should speak with your healthcare provider.
Are there any serious risks associated with levonorgestrel?
Levonorgestrel is generally safe and effective when used as directed. However, like all medications, it can have some serious risks, including:
- Blood clots: There is a small increased risk of blood clots with the use of birth control pills containing levonorgestrel. This risk is highest in women who are older, have high blood pressure, smoke, or have a history of blood clots.
- Breast cancer: There is some evidence to suggest that long-term use of birth control pills containing levonorgestrel may slightly increase the risk of breast cancer. However, the overall risk of breast cancer in women who use birth control pills is low.
If you have a personal or family history of breast cancer or blood clots, or if you are over the age of 35 and smoke, you should speak with your healthcare provider about your specific risks and whether levonorgestrel is an appropriate contraceptive option for you.
How effective is levonorgestrel at preventing pregnancy?
The effectiveness of levonorgestrel as a contraceptive depends on how it is used. When taken as directed, levonorgestrel is generally considered to be very effective at preventing pregnancy when used as directed. The typical failure rate for birth control pills containing levonorgestrel is around 1% per year. This means that if 100 women use levonorgestrel-containing birth control pills for one year, about one of them will become pregnant. The failure rate is higher in women who forget to take their pills or take them at irregular intervals. Emergency contraception with levonorgestrel is also generally effective, but it is not as effective as regular, consistent use of birth control pills or other methods of contraception.
Can I use levonorgestrel if I’m breastfeeding?
Levonorgestrel is not typically recommended for use in women who are breastfeeding. It can pass into breast milk and may decrease milk production. If you are breastfeeding and need contraception, you should speak with your healthcare provider about your options. There are other types of birth control pills and methods of contraception that are safe to use while breastfeeding.
Can I use levonorgestrel if I have certain medical conditions?
Levonorgestrel may not be safe or appropriate for all women. You should speak with your healthcare provider about your specific medical history and any conditions you have before starting levonorgestrel. Some conditions that may affect your ability to use levonorgestrel safely include:
- Liver disease
- Cancer of the breast or uterus
- A history of blood clots
Your healthcare provider will help you weigh the potential benefits and risks of levonorgestrel and decide if it is a good option for you.
