Most religious leaders agree that using an inhaler does not break your fast. Also, as explained in the text above, the taste of any medicine does not nullify the fast, therefore a residual taste which remains from an inhaler would also not break the fast (though after steroid inhalers it is recommended to rinse ones mouth as the usual procedure anyway). So to be clear, you Can use your inhaler while fasting.
13th July 2013Asslamo Allaikum Wa Rahmatullahi Wa Barakatuh,I had searched this matter for many years and failed to understand as to how using an inhaler breaks the fast. Modern day inhalers can be used with or without the spacers so there is very little chance that the medicine actually goes inside the stomach.
We also know that Inhalers have no nutritional value as such, so does it break the fast?Reviewing old Fatawa on the subject, many of them assumed that there is a danger that medication can actually go inside the stomach.
Does using inhalers as medication to cure asthma and many more diseases break one’s fast?Turkish Presidency of Religious Affairs (T.P.R.A.) High Council of Religion has a ruling about the inhalers that are widely used by people who suffer from shortness of breath:“Inhalers that are used to treat lung diseases spray very small amount, such as 1/20 ml into mouth, in one dose. Majority of this dose is absorbed and disappears in the mouth and bronchus walls. It is not clear whether the rest of it reaches the stomach with saliva. Comparing to the water remaining in mouth during ablution, it is clear that remainder of the inhaler is very little.
However, the remainder of the water in mouth during ablution does not break the fast, even if it reaches the stomach. There is a hadith (Darimi, Fast, 21) and consensus of Islamic scholars about this.Furthermore, it is inevitable that fiber and chemical remainders from miswak will reach the stomach, still it was stated in a sound Hadith (Bukhari, Fast, 27; Tirmidhi, Fast, 29) that Prophet Muhammad used miswak while fasting. In fact, according to “ Certainty is not overruled by doubt ” principle, if it is not clear that it reaches the stomach we cannot claim that it will break one’s fast.Therefore, asthma patients with no other disease, and still being able to fast, can use the inhalers including oxygen in order to breathe easily. Those sprays won’t break their fast.”(‘’ dated decree under the heading ‘Inspection and Treatment Methods Which Break and Do Not Break the Fast’).
