The start of the cold and flu season is upon us and many people get relief using a nasal spray. However, Pharmacist Angela Giallourakis says when using a nasal spray never direct it at the nasal septum, that’s that middle portion of your nose.

“When you push a spray directly on to it, it can cause some damage on that tissue and you can end up with some irritation or a bloody nose. So making sure it's pointed more towards the back so that you're actually able to inhale the product.”

Experts also caution that overuse of nasal sprays can lead to a rebound phenomenon where using the product too often causes your stuffy nose to get worse.
