In January 1997, 62 subjects who had been the placebos in the 1995 study were invited to receive the vitamin B12. In June 1997, the 62 placebo subjects were sent a questionnaire asking: How would you compare your overall allergy (hay fever) symptoms this spring to the last two springs? 20 people responded, with 15 reporting having had the B12 treatment, and 5 homeremedyasthma not. 12 of the 15 reported at least a slight improvement in overall allergy symptoms, and 1 of the 5. Improvement ratios - 12:3 having received treatment, 1:4 not having received treatment.8 A bioequivalence study showed that a 3000 mcg lozenge delivered an equivalent amount of cyanocobalamin to the blood as a 15 mcg injection.9 From the spring to the summer patients with demonstrated allergic rhinitis received with the cyanocobalamin (or placebo) containing lozenge twice daily for 21 consecutive days. All subjects also received C and B oral multivitamins for 21 days. Twice daily subjects maintained a nine-week diary on sneezing, runny nose, nasal congestion, itchy eyes, itchy nose and antihistamine (chlorpheniramine) homeremedyasthma use. In the post-treatment homeremedyasthma period, the active group (n=15) recorded on average a greater reduction in symptoms and in antihistamine use than the placebo group (n=9). The results yielded reductions (0.1>p>0.01) in total weekly symptom/rescue medication for the active group compared to the placebo for weeks 2, 6, 8 and 9. The results tend to replicate those of the studies on injectable cyanocobalamin.10

Genentech and Novartis are developing an anti-IgE monoclonal antibody for asthma and allergic rhinitis. In December 1999 they announced homeremedyasthma positive study results. This is evidence that reducing IgE results in a reduction of symptoms associated with IgE-mediated allergic disease.13 For people who find they cannot adequately avoid the allergens, the symptoms often can be controlled with medications. Effective medications that can be prescribed by a physician include antihistamines, topical nasal homeremedyasthma steroids, and cromolyn sodium - any of which can be used alone or in combination. Many effective antihistamines and decongestants also are available without a prescription. Click here for allergy medication online.

In homeremedyasthma 1992 in El Paso, TX a randomized, double-blind, placebo controlled study of subjects (n=130) with allergic rhinitis in 1992-1993 was conducted. The average homeremedyasthma IgE level of the placebo treated subjects remained essentially flat, while the average IgE level for active treated subjects was reduced significantly from baseline to Day 30.7 In 1993 in El Paso, TX, valid subjects (n=66) returned a second set of symptom diaries which they had completed for days 365 to 395 (the same period, 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
