Question:
Assalamualaikum.

I was wondering if using the inhaler during fasting breaks your fast? Can you please explain if it does or not?

Answer:

In the Name of Allah, the Most Gracious, the Most Merciful.

As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.

In principle, if only air is taken in the body, the fast is not invalidated. However, if any medication is entered into the body, the fast will be invalidated.[1]

An inhaler is a medical device used for delivering medication into the body via the lungs.[2] The medicine is a mist or spray that the person breathes in.[3]

Hence, the usage of an inhaler will invalidate the fast.

And Allah Ta’āla Knows Best
