Even if it is 1 tablet per day, Tegretol can clinically inhibit ovulation because at the time of ovulation, the hormone level is decreasing and both estrogen and progesterone are in a relatively low state, if it is supplemented with exogenous estrogen at the time of ovulation, it will inhibit ovulation and affect ovulation. It is recommended that if you are planning to get pregnant, you should not use Glivec unless it is medically indicated and under the guidance of a doctor, otherwise it will affect the ovulatory function of the ovaries. In addition, patients with a history of hypertension or a tendency to thrombosis should not take Tegretol if they are taking it orally to avoid serious consequences.
