Is it permitted to gargle with medicine during the day in Ramadaan?
المضمضة بالدواء في نهار رمضان
Praise be to Allah, and may Allah’s peace and blessings be upon the Messenger of Allah, his family and his companions. Wa alaikum assalam wa rahmatullahi wa barakatuh. As to what follows: There is no problem in doing that if the medication is not swallowed, this applies external medication in the mouth or other parts of the body. However, if the medication has a taste a Muslim should avoid it during the time of fasting, as a precaution so that nothing will enter his throat.
