Can I use nasal spray while fasting?

It depends: scholars differ, and many today say a light nasal spray is fine if you don't swallow it. The nose is a route to the throat, so classical scholars were stricter here than with eye drops. If you can use it at suhoor and iftar, that is the safest choice.
Why the nose is treated differently
The nose connects directly to the throat. The Prophet ﷺ told a companion to rinse his nose thoroughly in wudu, except when fasting (Sunan Abi Dawud 142). Scholars took from this that anything going deep into the nose can reach the throat and affect the fast.
That is why the four schools agree that nasal drops or liquid that clearly reaches the throat and is swallowed break the fast, and the day should be made up.
What scholars say about sprays today
A modern nasal spray (for allergies, a blocked nose or a steroid treatment) gives a very fine mist, and most of it stays in the nose. Scholars have two main views:
- Doesn't break the fast: many contemporary scholars and the International Islamic Fiqh Academy say a nasal spray is fine as long as you don't swallow what reaches your throat. They compare it to the small amount of water left in the nose after wudu.
- Breaks the fast: others, following the classical rule about the nose, say any spray that reaches the throat breaks it and should be avoided during the day.
Both views are respected. If your local imam follows one of them, you can follow it too.
Practical ways to stay on the safe side
- Use once-a-day sprays at suhoor or after iftar.
- Spray gently, without sniffing hard, so it stays in the nose.
- If you taste it in your throat, spit it out rather than swallowing.
- Saline rinses and neti pots send a lot of water into the nose, so keep those for after sunset.
The same "don't swallow it" principle is used for brushing your teeth. See Can I brush my teeth while fasting?
Nasal vaccines and medical needs
The nasal flu vaccine given to children is a spray, so the same difference of opinion applies. Many parents simply book it outside fasting hours. For vaccines in general, see Are vaccines halal for Muslims?
If you need a nasal spray during the day for a real medical reason and your scholar's view is that it breaks the fast, remember that illness is a valid reason to break the fast and make it up later. Never stop a treatment your doctor has prescribed.
- Nasal drops that reach the throat break the fast for all four schools.
- Many scholars today say a light spray is fine if you don't swallow it; others disagree.
- Use sprays at suhoor and iftar whenever possible.
- If you need it for illness during the day, your health comes first.
