What is this medication for?

Ryaltris® is used to treat moderate to severe symptoms associated with allergic rhinitis.

Allergic rhinitis is the inflammation of the nasal cavity, which leads to sneezing, itchy nose, blocked or runny nose symptoms.

Ryaltris® contains two active ingredients — olopatadine and mometasone furoate. Olopatadine works by blocking the effects of histamine, a substance in the body that causes allergy symptoms. Mometasone furoate is a corticosteroid that reduces and prevents inflammation. Together, they help relieve symptoms such as a blocked or runny nose, nasal itching, sneezing and eye symptoms.

How should I take or use this medication?

  • Do not stop using your medication without checking with your healthcare professional. 

  • Ryaltris® is a nasal spray for use in your nose only. Avoid spraying Ryaltris® into the eyes or mouth. 

  • Administer using the following steps below: 

Preparing the nasal spray bottle (Priming)

Step 2: 

  • Hold the nasal spray bottle firmly and upright with your index and middle finger on either side of the spray nozzle unit (on finger rests) while supporting the grooved base of the bottle with your thumb. 
  • Before first use, spray the product 6 times or until a fine mist appears, away from eyes and face.
  • If you have not used Ryaltris® for 14 or more days, you will need to prime the pump with only 2 sprays or until a fine mist appears.

Step 7: Then breathe out through your mouth. Repeat Steps 3 to 5 for the other nostril. Do not blow your nose for at least 15 minutes after using Ryaltris®, to make sure that you receive the full dose.

Step 8: After each use, wipe the white spray nozzle tip with a clean dry tissue or cloth. Replace the purple dust cap tightly onto the nozzle. 

Troubleshooting if nozzle tip gets blocked 

  • Remove the spray nozzle unit by gently pulling upward. Remove the purple dust cap and place only the spray nozzle unit in warm water to soak. 

  • After soaking the spray nozzle tip for 15 minutes, rinse the spray nozzle unit and purple dust cap with warm water and allow them to dry completely. 

  • You should clean your nasal spray at least once a week to stop it from getting blocked up. 

  • Do not try to unblock the spray nozzle tip by inserting a pin or other sharp object. This will damage the spray nozzle tip, and you may not get the correct dose of medicine. 

What should I do if I forget to take or use this medication?

If there are no specific instructions on when to take a missed dose from your healthcare professional, take your missed dose as soon as you remember, if it is not close to the next dose.

For example, if you usually take your medication once a day at 8am and you miss the dose, you can still take the dose if you remember by 8pm on the same day (within 12 hours of your usual timing).
