Junel 1.5/30 is a combination birth control pill which is used to prevent pregnancy. The drug contains 2 hormones: ethinyl estradiol and norethisterone (also known as norethindrone).
Indications for use
Mechanism of action
A combination of ethinyl estradiol and norethisterone depresses the pituitary secretion of gonadotropic hormones. The drug blocks the progestative and estrogenic components on the hypothalamic-pituitary-ovarian system, prevents the maturation of the follicle, i.e. blocks ovulation. The contraceptive (under the appropriate schemes of use) can both stimulate and delay menstruation and help stop the acyclic uterine bleeding.
Dosage and mode of application
Each Junel 1.5/30 pack contains 21 active tablets (ethinyl estradiol + norethisterone). The pack does not contain any inert tablets.
Take 1 tablet orally for 21 days in a row, followed by a 7-day break, during which the typical menstrual bleeding occurs. At the beginning of the treatment, after a prolonged interval or when switching from another contraceptive drug, the first tablet should be taken on the first day of the menstrual period. The tablets should be taken whenever possible at the same time (to ensure a constant concentration of hormones in the plasma).

Pregnancy and breastfeeding
The drug is not indicated for use during pregnancy. If pregnancy occurs during Junel 1.5/30 treatment, therapy should be discontinued immediately since norethisterone can affect the fetus. Doses exceeding those commonly used in preparations for oral contraception and hormone replacement therapy can cause masculinization of the female fetus.
Most epidemiological studies of the effect of estrogens and progestogens on the fetus have not revealed any teratogenic or embryotoxic effects.
Junel 1.5/30 is not indicated for use during breastfeeding.
What if I miss a pill?
The interval between Junel 1.5/30 tablets should not exceed 36 hours. If you miss a dose, take the drug within the next 12 hours. If the interval exceeds 36 hours, a reliable contraceptive effect is not guaranteed. During this period it is recommended to use other non-hormonal methods of contraception.
The drug is indicated only for women with regular menstrual periods.
