Standardized grass pollen extracts are used for the diagnosis and treatment of allergic disease to grass pollen. The standardized (Bioequivalent Allergy Unit) extract in these vials is designed primarily for the physician equipped to prepare dilutions and mixtures as required. STANDARDIZED GRASS POLLEN EXTRACTS L A BELED IN BAU/ml ARE NOT INTERCHANGEABLE WITH GRASS POLLEN EXTRACTS LABELED IN AU/ml OR WITH NON-STANDARDIZED (WEIGHT/VOLUME) GRASS POLLEN EXTRACTS. Patients being switched from other types of extracts to Allergy Laboratories should have their dose adjusted. Diagnosis of allergic disease to these grasses is made through a combined medical history sufficiently complete to identify allergic symptoms to grass pollen and identification of grass allergy by diagnostic skin testing. It is recommended that diagnostic skin testing (scratch or puncture) be performed with 10,000 BAU/ml grass pollen extracts before testing with 100,000 BAU/ml grass pollen extracts. 10,000 BAU/mL and 100,000 BAU/ml grass pollen extracts for immunotherapy are available for previously treated patients to facilitate dose selection for safe switching from non-standardized to standardized extracts. Patients being treated with grass pollen extracts for the first time can be initially immunized with dilutions prepared from the 10,000 BAU/ml extract (see Dosage and Administration). 100,000 BAU/ml grass pollen extract can be administered if the patient tolerates the 10,000 BAU/ml extract. Grass pollen immunotherapy is intended for patients whose grass allergic symptoms cannot be satisfactorily controlled by avoidance of the offending allergen or by the use of symptomatic medications.
