What are allergies?

Allergies are manifested when the immune system overreacts to a foreign substance such as pollen, animal dander, mold, mites and dust that normally does not cause problem to the majority of people. When an allergy occurs, the immune system creates antibodies that identify allergens as being harmful, despite the fact that they are not.

How to help avoid your symptoms of allergies?

Treat when symptoms begin and as long as allergy triggers remain.

MosasprayTM is an effective medication

MosasprayTM is a Mometasone furoate monohydrate aqueous nasal spray. Mometasone is the No.1 selling allergy nasal spray in Canada1. Clinical evidence supports that intranasal corticosteroids are the first-line-treatment in the management of allergic rhinitis and provide greater relief of allergic rhinitis symptoms than antihistamines alone2,3,4.

Directions for use

  2. Gently blow your nose to clear the nostrils. With your finger, hold one nostril shut. Tilt your head forward slightly, keep the bottle upright, and carefully insert the nasal applicator into the other nostril. Do not spray directly onto the nasal septum (the wall between the two nostrils).
  3. Hold the spray bottle upright and press firmly downward on the shoulders of the nasal applicator. Breathe gently inward through the nostril. Then breathe out through the mouth. Adults and children 12 years and over: two sprays in each nostril.
  4. Repeat in the other nostril.
  5. Wipe the outside of the nasal applicator with a clean tissue and replace the plastic cap after each use.


MosasprayTM is for adults and children (12 years of age and older) with symptoms of allergies. Once daily, spray two times into each nostril while sniffing gently. When you symptoms are under control, you may reduce to one spray into each nostril per day. Full effect depends on daily and continued use as long as allergy triggers remain.
