Would the questioner be considered a suicide if she continues to take a medication to regulate her menstrual cycle, knowing that it has been discontinued in Europe due to causing deaths, and she fears that her taking it would be tantamount to self-destruction?

There is no harm in continuing to take the medication if specialized doctors determine that it is not harmful. You would not be considered a suicide if you passed away while taking it. The sale of this medication in several countries indicates that it is not dangerous, and some countries prohibiting it might be a precautionary measure or due to the availability of alternatives. Therefore, there is no harm in following the doctors' advice and continuing to take the medication, along with their other recommendations.
