Using Pills to Stop Haidh in Ramadhaan Question: Is it permissible for a lady to use pills to prevent her period in the month of Ramadhaan or not? Answer: It is permissible for a lady to use medication to prevent her monthly period if experienced doctors give her the assurance that it will not harm her reproductive system, but the best thing for her is to avoid that, and Allaah has permitted her to break the fast whenever the period comes in Ramadhaan, demanding a replacement of the days she missed, and is pleased with her if she does that. (Shaikh Ibn Baaz AdDa’awaah: 797)
