What is the ruling on a woman taking medication to prevent the onset of menstruation?

Question : I am a woman whose monthly period comes during this noble month, from the twenty-fifth to the end of the month. If I menstruate, I will lose a great reward. So I take pills to prevent menstruation, especially since I asked the doctor and he said they do not harm me.

Answer : Yes. I say to this woman and to women like her whose menstruation comes during Ramadan: even if she misses what she misses of prayer and recitation, that is by the decree and destiny of Allah, and she must be patient. For this reason, the Prophet (peace and blessings be upon him) said to 'A'ishah when she menstruated: It is established with us that pills to prevent menstruation have an effect on health and on the uterus, and that it is possible for a fetus to be deformed because of these medications. Yes.
