Fasting: Does Using an Asthma Inhaler Break the Fast?

English:

Question #758:

Some people use ‘nās,’ which is made up of tobacco and other constituents, and they put it under their tongues for a few minutes, then they spit it out. Does that void the fast?

Answer #758:

This spray, which is used to open respiratory tract, does not invalidate fast. However, if the air is mixed with medicine in the form of powder, the fast’s validity is problematic and thus it is obligatory to avoid it. However, if fasting without it is difficult or harmful, using the medicine is permissible.
