Is it permissible to use a nasal spray that contains a percentage of alcohol? Does it break the fast for one who is fasting?

Firstly: 

We ask Allah
to heal you and grant you well being. We inform you that there is nothing
wrong with using this medicine that contains that percentage of alcohol,
which is very low and is dissolved in the medicine and there is no apparent
trace of it, so it does not come under the ruling prohibiting
alcohol.                           

We have quoted
the fatwas of the scholars concerning that. Please see the answer to
question nos. 146013 and
111851. 

Secondly: 

Using sprays
for allergies does not invalidate the fast according to the correct opinion,
whether they are administered through the nose or through the mouth, as they
are in the form of vapour and do not contain any solid matter that enters
the stomach. 

Shaykh
Muhammad ibn Saalih al-‘Uthaymeen (may Allah have mercy on him) was asked: 

I have an
allergy that affects my nose and I use a nasal spray to treat it. If I do
not use it, it causes me great difficulty in breathing and I cannot do
without the medicine for more than three hours. If I do not use it, it will
make breathing very difficult. The problem is that the month of Ramadan is
coming and I use this medicine and am afraid it will affect my fast, but if
I stop using it I cannot cope. Please note that on some days in Ramadan I
did use it but I am very careful to prevent it from reaching my throat. What
is the ruling on that? And what is the ruling on using it? 

He replied: 

We ask Allah
to heal you and grant you well being. The answer to your question is that
this spray that you are using is like a kind of gas because it is dispersed
in the air and does not reach the stomach. As that is the case, we say that
there is nothing wrong with using this spray when you are fasting and you
are not breaking the fast by doing that because – as we have said – no part
of it reaches the stomach because it is something that is dispersed in the
air and disappears, and no particle of it reaches the stomach such that we
could say that it is something that breaks the fast. So it is permissible
for you to use it when you are fasting.

See also the
fatwas of the scholars ruling that using puffers for asthma in the mouth
does not break the fast, in the answer to question no.

This was also
stated in a fatwa by Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allah have mercy on
him) about using nasal sprays, as we have quoted from him in the answer to
question no. 106494. 

And Allah knows best.
