Alesse is a monophasic hormonal birth control preparation. It contains ethinyl estradiol and levonorgestrel. This birth control drug is applied for an unwanted pregnancy prevention. It should be taken considering doctor’s recommendations.
- Hormone-dependent functional disorders of the menstrual cycle (including dysmenorrhea, menorrhagia without an organic cause, premenstrual syndrome).
Mechanism of action
Alesse is a contraceptive combined estrogen-gestagen drug. When taken, it inhibits the pituitary secretion of gonadotropic hormones. The contraceptive effect is implied due to several mechanisms. As a progestin component, Alesse contains a 19-nortestosterone derivative – levonorgestrel. It excels progesterone in the activity of the corpus luteum hormone and acts at the receptor level without preliminary metabolic transformations. Ethinyl estradiol is estrogen component. Under the influence of levonorgestrel, there is a blockade of the release of releasing factors (LH and FSH) of the hypothalamus. It also provides the suppression of pituitary secretion of gonadotropic hormones. It contributes to the inhibition of maturation and the release of an egg ready for fertilization (ovulation). The contraceptive effect is enhanced by ethinyl estradiol. It maintains a high viscosity of cervical mucus. When taken these nirth control pills regularly, it normalizes the menstrual cycle and helps to prevent the development of a number of gynecological diseases, including tumor nature.
Mode of application and dosage
Oral administration. 1 tablet of Alesse 1 time per day, starting from 1 or 5 days of the menstrual cycle (depending on the type of drug used: monophasic, 2- or 3-phase) for 21 days. Then a 7-day break is followed.
Alesse 28 is taken without any breaks. The latest seven pills contain placebo having no effect on female health. These 7 pills are colored in white.

Barbiturates, some antiepileptic drugs (carbamazepine, phenytoin), sulfonamides, pyrazolone derivatives can enhance the metabolism of the steroid hormones that are a part of this birth control drug.
A decrease in contraceptive effectiveness can also be found with the simultaneous administration with certain antimicrobial drugs (ampicillin, rifampicin, chloramphenicol, neomycin, polymyxin B, sulfanilamides, tetracyclines), which is associated with a change in intestinal microflora.
When taking gestagen-estrogenic drugs, it may be necessary to adjust the dosage regimen of hypoglycemic drugs and indirect anticoagulants.
What if I miss a dose?
