On what basis does the doctor choose contraceptive pills?

The decision to prescribe a specific hormone therapy is made by the doctor individually each time, based on the current state of health, medical history, existence or absence of contraindications and the patient's preferences. Without the above information, it is not possible to assess the accuracy of the drug selection. In this matter, it is worth trusting the attending physician. You should be aware that irregular, prolonged bleeding and spotting may occur in the first months of using birth control pills. This does not mean that the tablets were poorly selected, the body during this period adapts to the hormonal changes that occur under the influence of the drug. Usually this period lasts up to 3 months. More about two-component tablets can be read in the text: https://www.gdziepolek.pl/kategorie/tabletki-antykoncepcyjne-dwuskladnikowe
