What is Levonorgestrel + Ethinyl Estradiol used for?
This combination hormone medication is used to prevent pregnancy. It contains 2 hormones: a progestin (levonorgestrel) and an estrogen (ethinyl estradiol). It works mainly by preventing the release of an egg (ovulation) during your menstrual cycle. It also makes vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization) and changes the lining of the uterus (womb) to prevent attachment of a fertilized egg. If a fertilized egg does not attach to the uterus, it passes out of the body.
Besides preventing pregnancy, birth control pills may make your periods more regular, decrease blood loss and painful periods, decrease your risk of ovarian cysts, and also treat acne.
How should I take Levonorgestrel + Ethinyl Estradiol?
Take this medication by mouth as directed by your doctor, usually once daily. Pick a time of day that is easy for you to remember, and take your pill at the same time each day.
It is very important to continue taking this medication exactly as prescribed by your doctor. Follow the package instructions to find the first tablet, start with the first tablet in the pack, and take them in the correct order. Do not skip any doses. Pregnancy is more likely if you miss pills, start a new pack late, or take your pill at a different time of the day than usual.
Taking this medication after your evening meal or at bedtime may help if you have stomach upset or nausea with the medication. You may choose to take this medication at another time of day that is easier for you to remember. No matter what dosing schedule you use, it is very important that you take this medication at the same time each day, 24 hours apart. Ask your doctor or pharmacist if you have any questions.
Begin taking this medication on the first Sunday following the beginning of your menstrual period. If your period begins on a Sunday, begin taking this medication on that day. Your pill pack contains 84 active pills (with hormones) and 7 inactive pills (without hormones). Take one active pill daily for 84 days in a row. The day after you finish all the active pills, start taking one inactive pill daily for 7 days in a row. You should have your period during the week you are taking the inactive pills. The day after you take the last inactive tablet in the pack, start a new pack whether or not you have your period. If you do not get your period, consult your doctor.
If this is the first time you are using this medication, use an additional form of non-hormonal birth control (such as condoms, spermicide) for the first 7 days to prevent pregnancy until the medication has enough time to work. If you start on the first day of your period, you do not need to use back-up birth control the first week.
Ask your doctor or pharmacist about how to switch from other forms of hormonal birth control (such as patch, other birth control pills) to this product. If any information is unclear, consult the Patient Information Leaflet or your doctor or pharmacist.
