Mechanism of action
Ulipristal is a synthetic modulator. The drug has a specific effect on progesterone receptors. The principle of action is based on the suspension of the natural process of ovulation in women. The active substance retards the rupture of the follicle, provided it is taken right before the date of the proposed ovulation.
Dosage and mode of application

The drug can be taken regardless of foods.
If you had vomiting or diarrhea 3 hours after taking the drug, you should take an additional tablet.
The preparation can be taken any day of the menstrual period. Before using the drug, pregnancy should be excluded.

Therefore, the concomitant use of medications containing gestagen is not recommended;
- Gestagen-containing drugs should not be used within 12 days after taking ulipristal;

Precautions
The drug is intended only for occasional use and should not replace the methods of regular contraception. In any case, a woman should be advised to use the methods of planned contraception.
Typically, the menstrual period resumes within 4 weeks after the end of the course of treatment.
Ulipristal 30 mg does not prevent pregnancy in each case.
If the next menstrual period is delayed for more than 7 days, you have an abnormal menstruation or symptoms of pregnancy, a pregnancy test should be done. If the pregnancy occurred after taking Ulipristal, ectopic pregnancy should be excluded. It is important to remember that the occurrence of uterine bleeding does not exclude ectopic pregnancy. Women who have done a pregnancy after taking the drug should consult a doctor.
The medication inhibits or delays the onset of ovulation. If ovulation has already occurred, the drug is ineffective. The time of ovulation cannot be predicted, so the tablet should be taken as soon as possible after unprotected sexual intercourse.
There are no data on the effectiveness of Ulipristal 30 mg tablet after its use after 120 hours (more than 5 days) after unprotected sexual intercourse.
Limited data suggest that the efficacy of the emergency contraception may decrease with increasing body weight or body mass index (BMI). All women, regardless of body weight or BMI, should use emergency contraception as soon as possible after unprotected intercourse.
Contraception after taking Ulipristal
This drug does not provide a contraceptive effect in subsequent sexual acts. Therefore, after using emergency contraception, a woman should be recommended to use a reliable barrier birth control method before the next menstrual period.
Despite the fact that the use of the preparation is not a contraindication to continuing routine hormonal contraception, ulipristal acetate may reduce the contraceptive effect of routine hormonal contraceptives. Therefore, if a woman wants to begin or continue using hormonal contraception, she can do this after taking an emergency contraception tablet. At the same time, she should use a reliable barrier birth control method until she has the next menstrual period.
