According to the package leaflet of Drovelis, the use of the preparation after a miscarriage should be started according to the doctor's instructions.

In your case, your doctor recommended starting the drug after the start of menstruation.

I have attached a link to check the availability of the drug and make a reservation at the pharmacy of your choice:

If you have any doubts about the timing of the drug, I encourage you to consult your doctor again. You can also use the teleconsultation via the m.in portal Gdziepolek.pl:
