Oralair is a medication used for the treatment of grass pollen allergies.

Oralair is an allergen extract indicated as immunotherapy for the treatment of grass pollen-induced allergic rhinitis, which is characterized by symptoms such as sneezing, runny nose, itchy nose, and nasal congestion.

The mechanism of action of Oralair involves exposing the body to small amounts of the allergen extract, which helps the immune system become desensitized to the specific allergens present in grass pollen. This desensitization process can reduce the severity of allergic reactions and symptoms when exposed to grass pollen in the future.

Use and Dosage

Your doctor may perform an allergy skin test or blood test to make sure you are allergic to the specific pollen contained in Oralair.

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Your doctor may want to give your first dose of this medicine in a clinic setting. You should be watched closely for at least 30 minutes after taking your first dose, to make sure you do not have an allergic reaction.

Oralair is a sublingual tablet that dissolves under your tongue. Do not chew this tablet or swallow it whole.

To take the sublingual tablet:

  • Keep the tablet in its blister pack until you are ready to take it. Open the package and peel back the foil.
  • Use dry hands to remove the tablet and place it in your mouth.
  • Place the sublingual tablet under your tongue and allow it to dissolve completely.
  • Do not swallow for at least 1 minute. Do not eat or drink anything for at least 5 minutes.

A child using Oralair should be supervised by an adult while taking this medicine.

Oralair is usually taken once daily throughout allergy season. For the best results, start taking this medicine at least 4 months before the start of allergy season.

In some cases, you may need to take Oralair every day all year long, for up to 3 years. Follow your doctor’s dosing instructions very carefully.

Your doctor may also prescribe epinephrine (Epi-Pen) to keep with you in case you ever have an allergic reaction to Oralair.

If you need oral surgery or dental work, or if you have a mouth injury or infection, you may need to stop using this medicine until your mouth heals. Tell your doctor if the sublingual tablets cause any mouth irritation.
