This product should never be injected intravenously. Patients with cardiovascular diseases and/or pulmonary diseases such as symptomatic unstable, steroid-dependent asthma, and/or those who are receiving cardiovascular drugs such as beta blockers, may be at higher risk for severe adverse reactions. The allergens which have been studied are cat, mite, venoms, and some pollen extracts.9, 14, 15, 16, 17, 18, 19 Ig E antibodies bound to receptors on mast cell membranes are required for the allergic reaction, and their level is probably related to serum Ig E concentrations. Immunotherapy has been associated with decreased levels of Ig E, and also with increases in allergen specific Ig G "blocking" antibody.
Non-glycerinated extracts contain 0.5% sodium chloride, 0.275% sodium bicarbonate and 0.4% phenol (w/v) as a preservative. Allergens to which a patient is extremely sensitive should not be included in treatment mixes with allergens to which there is much less sensitivity, but should be administered separately.
