Salaam, I suffer from asthma. Is it permissible for me to use my Ventoline inhaler?
In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
In principle, the use of oral medication will invalidate the fast. Thus, if you use your inhaler whilst fasting, your fast will break.
If you suffer from an asthma attack whilst fasting and no other option is available except the use of your inhaler, you may make use of your inhaler and make up for your fast afterwards. You will only have to do qadhā’; kaffārah will not be required.
And Allah Ta’āla Knows Best
