Can I Use Antiseptic Cream During Fast in Ramadan?

Hanafi Fiqh

Answered by Ustadh Salman Younas


I suffer from mouth ulcers daily and apply an antiseptic on them. I was wondering if I could apply the antiseptic during Ramadan. Will that break my fast?


If the substance does not reach your throat, it will not invalidate the fast. Usually, one may assume that putting on a very small amount of antiseptic on a mouth ulcer would not break the fast. [al-Shurunbulali, Maraqi al-Falah]

It is still better to avoid putting on this antiseptic while you are fasting. If it is possible to put it on before the fast begins and then only reapply it after you open your fast, this would be optimal.
