Antihistamines As the name indicates, an antihistamine counters the effects of histamine, which is released by the mast cells in the body''s tissues and contributes to allergy symptoms. For many years, antihistamines have proven useful in relieving sneezing and itching in the nose, throat, and eyes and in reducing nasal swelling and drainage. Many people who take antihistamines experience some distressing side effects: drowsiness and loss of alertness and coordination. In children, such reactions can be misinterpreted as behavior problems. During the last few nutritionanddiet years, however, antihistamines that cause fewer of these side effects have become available by prescription. These new nonsedating antihistamines are as effective as other antihistamines in preventing histamine-induced symptoms, but do so without causing nutritionanddiet sleepiness.

Jay M. Symptoms not very bad. Karl L. My congestion allergies did seem to get better after several days...Marsha R. I had some better days. Erin C. I believe it helped to a certain extent. William R. Improved after 3 days. Nancy C. On day 16 I felt so much better, by day 30 allergies continued nutritionanddiet to be improved. Angel C. Background of Cyanocobalamin Treatment in Allergic Disease MECHANISM OF ACTION: Vitamin B12 is essential to cell growth and cell division. B12 is the only known molecule in the human body uses with the element cobalt. The unique properties of cobalt permit a chemical reaction nutritionanddiet that produces the rungs of the DNA ladder. These rungs are called nucleotides. For any human cell to divide, it must copy its own DNA. For this replication to occur, new rungs of the ladder must be provided with the help of B12.

In 1992 in El Paso, TX a randomized, nutritionanddiet double-blind, placebo controlled study of subjects (n=130) with allergic rhinitis in 1992-1993 was conducted. The average IgE level of the placebo treated subjects remained essentially flat, while the average IgE level for active treated subjects was reduced nutritionanddiet significantly from baseline to Day 30.7 In 1993 in El Paso, TX, valid subjects (n=66) nutritionanddiet returned a second set of symptom diaries which they had completed for days 365 to 395 (the same period, nutritionanddiet one year after the first set of symptom diaries). The active group had mean symptom scores showing statistically significant decreases from 1992 to 1993. The placebo group had increased symptoms in 1993. (The relevant pollen counts at the study site in 1993 were much higher than in 1992, leading to expectation of higher symptoms.)7
