I'm sorry, but the Official List of Medicinal Products does not contain information about a drug called "Praveran" to delay menstruation. It seems that there may have been a mistake in the name of the drug.

If you would like information about Provera, which is used to regulate and postpone periods, read on.

Provera is a hormonal drug available only on prescription, so the legitimacy and need of its use in therapy is assessed by a doctor. Do not use this preparation without consulting your doctor. The dosage and method of use should be determined by the doctor, as they depend on the individual situation of the patient.

Generally, in order to postpone menstruation, Provera is usually taken three days before the planned menstrual period. It may postpone the period by up to 7 days or until you stop taking the medicine.

Please remember that the use of hormonal drugs to control the menstrual cycle should always be done under the supervision of a gynecologist. Modifying the dosage on your own or using the drug without medical consultation can be dangerous to your health. If you are not able to make a face-to-face visit, I attach a link to the online teleconsultation:
