Can Kostarox delay menstruation?

The Kostarox documentation does not contain information that a delay in menstruation is observed as a side effect of the drug. However, this does not mean that there is definitely no connection, as some rare side effects may not be described in the leaflet. However, if you are sexually active, then in the absence of menstruation on time, pregnancy should be ruled out in the first place. The lack of a period within about 10-14 days from the expected date - if you have menstruated regularly so far - should prompt you to contact a gynecologist.
