Grass pollen allergenic extract is used to decrease the symptoms of moderate-to-severe seasonal allergies to grass pollens, when other allergy treatments have not been effective. This medication belongs to the class of medications called allergy immunotherapies. It works by causing the body’s immune system to become less sensitive to the effects of the pollen.

Uses and Dosage

Follow your doctor’s instructions and take this medication orally, on an empty stomach, typically once daily. With dry hands, extract a single tablet from its packaging just before consumption. Place the tablet beneath your tongue, allowing it to dissolve for at least 1 minute before swallowing—refrain from chewing or swallowing the tablet.

Abstain from eating or drinking while the tablet dissolves in your mouth and for 5 minutes post-consumption.

After handling the tablet, remember to wash your hands.

If necessary, ensure that an adult assists a child in correctly taking this medication. Monitor the child for at least 30 minutes after each dose to detect any potential allergic reactions.

For certain brands of this medication, your doctor might instruct you to initiate treatment with a low dose, gradually increasing it to minimize the risk of side effects. Adhere closely to your doctor’s guidelines.

Typically, your doctor will advise starting this medication about 4 months before the anticipated onset of allergy season, continuing throughout the season. Consistently use the medication to maximize its benefits, and to aid your memory, take it at the same time daily.

Inform your doctor if there’s no improvement in your condition or if it worsens.

Oralair is not a medication that gives immediate relief of allergy symptoms; it is an allergy immunotherapy. Treatment with Oralair is started about 4 months before the allergy season begins and continues throughout the grass allergy season.

Can my child take Oralair?

Oralair may be prescribed for children 5 years and older whose allergy specialist has confirmed they are allergic to any of the grass pollens contained in Oralair.
