What is Azelair Nasal Spray Used For?

Azelair is used to relieve nasal symptoms of allergic rhinitis such as congestion, sneezing, itching, and a runny nose. It works quickly by blocking the effects of histamine, helping you breathe more easily and comfortably during allergy flare-ups.

Who is Azelair Suitable For?

Azelair is suitable for adults, adolescents, and children aged 6 years and over.

Do not use Azelair if you:

  • Are allergic to azelastine hydrochloride or any of its ingredients

Speak to your doctor or pharmacist before use if you:

  • Are pregnant or breastfeeding (use with caution)
  • Experience dizziness, tiredness, or fatigue — as these can affect driving or operating machinery
  • Consume alcohol regularly — as it can enhance drowsiness or weakness

How to Use Azelair Nasal Spray

  1. Blow your nose gently before using the spray.
  2. Shake the bottle and remove the cap.
  3. Prime the spray by pressing down several times until a fine mist appears (only before first use).
  4. Insert the nozzle into one nostril while keeping the other closed.
  5. Spray once (or twice, if advised) while inhaling gently through your nose.
  6. Repeat for the other nostril.

Avoid tilting your head too far back, as this may cause an unpleasant taste.
