BreathiZen is sprayed into the mouth or onto the tongue. It is not a nasal product.
A nasal spray is used in the nose, often as a medicine or saline product. BreathiZen is a dietary supplement taken orally, so do not spray it into the nose.
Follow the label for every product you use. If you use a nasal spray prescribed by a doctor, do not stop it because you started a supplement, and tell your doctor.
