How does Phleum Pratense work?

Phleum pratense in very small doses is thought to desensitize the body to grass pollen allergies.

Are there safety concerns?

Phleum pratense seems safe for most adults and children aged 3-16 years. When used under the tongue (sublingually), Phleum pratense can cause itching and irritation of the mouth and nose, blisters in the mouth, and runny nose.

When given by injection, it can cause irritation at the injection site.

Do not take Phleum pratense if:
  • You are pregnant or breast-feeding.

Dosing considerations for Phleum Pratense.

The following doses have been studied in scientific research:

UNDER THE TONGUE:
  • For hay fever: 75,000 units of a specific standardized Phleum pratense allergen product (Grazax, Alk Abello) daily, starting 8 weeks before grass pollen season starts and continued until it ends.
INJECTED UNDER THE SKIN:
  • For hay fever: 100,000 units of a specific Phleum pratense allergen product (Alutard SQ, Alk Abello) twice weekly starting 8 weeks before grass pollen season starts and continued until it ends.
