Indications
Select 21-day is an oral contraceptive medication used to prevent pregnancy. In addition to its contraceptive effects, birth control pills may also have other benefits such as regulating menstruation, reducing pain and blood loss during periods, lowering the risk of ovarian cysts, and treating acne.
Select 21-day consists of two hormones, namely an Ethinyl estradiol and Norethindrone. They work by preventing ovulation, thickening the cervical mucus to prevent sperm from reaching the egg, and thinning the lining of the uterus to make implantation of a fertilized egg less likely.
Use and Dosage
Select 21-day pills are designed to be taken for 21 days, followed by a 7-day break period. During this break period, you may experience withdrawal bleeding, which is similar to a menstrual period. Taking the pills after your evening meal or at bedtime may help if you have stomach upset or nausea with the medication. You may choose to take it at another time of day that is easier for you to remember.
To use Select 21-day contraceptive pills, take one pill every day at the same time, for 21 consecutive days. Try to take the pill at the same time every day to maintain consistency. After you have taken all the pills in the pack, take a 7-day break, during which you will not take any pills. You should start your next pack of pills on the eighth day, even if you are still experiencing withdrawal bleeding.
If you miss one pill, take it as soon as you remember, and take the next pill at the usual time. This means that you might take 2 pills in one day. If you miss 2 pills in a row during the first 2 weeks of your cycle, take 2 pills the day you remember and 2 pills the next day, then take one pill a day until you finish the pack. Use a second method of birth control if you have sex in the 7 days after you miss the pills.
If you miss 2 pills in a row during the third week of your cycle or 3 or more pills at any time during your cycle and you start your pills on Day 1, safely dispose of the rest of the pill pack and start a new pack that same day. Use another method of birth control if you have sex in the 7 days after you miss the pills. You may not have a period this month. If you miss 2 periods in a row, call your doctor or clinic.
