Loestrin is a contraceptive pill used to prevent pregnancy. It works by mimicking the boby’s natural hormones estrogen and progesterone; the active ingredients in Loestrin are ethinylestradiol and norethisterone.
Used for treating: contraception / birth control
Effect: suppresses ovulation and prevents the implantation of the egg
Loestrin contraceptive pill contains two active ingredients: ethinylestradiol and norethisterone. These synthetic hormones prevent ovulation, no egg should relased by the body and can therefore not be fertilised by sperm. Ethinylestradiol and norethisteron also change the womb lining, making it much harder for an egg that would be released, to settle in the womb. At the same time the mucus in the womb is thickened, forming a natural barrier between the egg and sperm.
How do ethinylestradiol and norethisterone affect the menstrual cycle?
Through a combination of estrogen with progesterone the normal menstrual cycle of the woman continues despite the lack of ovulation. The monthly menstruation takes place in the stop week of the pill. The menstrual period might be lighter and less painful when you use Loestrin. For this reason, some of these contraceptive drugs are also prescribed for women with painful period pains or irregular menstrual cycles.
What is the difference between Loestrin 20 and Loestrin 30?
Loestrin 20 has a lower dose of hormones (20 mcg ethinyl estradiol and 1.00 mg norethindrone) than Loestrin 30 which has a slightly higher dose of hormones (30 mcg of ethinyl estradiol and 1,50 mg norethindrone). Loestrin 20 is therefore considered a low dose pill which is often used by young women who are just starting birth control. Loestrin 30 is a regular dose birth control pill.
How to use Loestrin?
You take Loestrin once a day. Make sure the day you take it corresponds with the day marked on the strip. A strip of Loestrin contains 21 pills, so you take a pill every day for 3 weeks, then you don’t take any pills in the 4th week, allowing menstruation to occur. After 28 days you start with a new strip, therefore day 29 becomes the new day 1 and you continue this for another 28 days. If you take all your pills correctly, Loestrin protects 99% against pregnancy. You are also protected from pregnancy in your stop week (days 22-28) as long as you keep losing it correctly.
