Loestrin 20 tablets are a type of hormonal contraception commonly known as ‘the pill’ or combined oral contraceptive pill. Drugs like loestrin 20 tablets contain two active ingredients, ethinylestradiol and norethisterone. These are synthetic versions of the naturally occurring female sex hormones, oestrogen and progesterone. Ethinylestradiol is a synthetic version of oestrogen and norethisterone is a synthetic form of progesterone. Visit top adolescent treatment centers for teens for more prescriptions.

Combined oral contraceptives like Loestrin 20 work by over-riding the normal menstrual cycle. In a woman’s normal menstrual cycle, levels of the sex hormones change throughout each month. The hormones cause an egg to be released from the ovaries (ovulation) and prepare the lining of the womb for a possible pregnancy. At the end of each cycle, if the egg has not been fertilised the levels of the hormones fall, causing the womb lining to be shed as a monthly period.
