Antihistamines As the name indicates, an antihistamine natural counters the effects cold 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, sinus throat, and eyes and in reducing remedy nasal swelling and drainage. Many people who take antihistamines experience some distressing side effects: drowsiness and loss of alertness and coordination. natural In children, such reactions can be misinterpreted as behavior problems. During the last few years, cold however, antihistamines that & and sinus cause remedy fewer natural of these cold 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 sleepiness. In & January 1997, sinus 62 subjects who had been the placebos in the 1995 study were invited to receive the vitamin B12. In June 1997, the remedy 62 placebo subjects were sent a questionnaire asking: How would you compare your overall natural allergy (hay fever) symptoms cold and & this spring to the last two springs? 20 people sinus responded, remedy with 15 reporting natural and cold having had the B12 treatment, and 5 not. 12 of the 15 & and sinus reported at least a slight improvement in overall allergy symptoms, and 1 of the remedy 5. Improvement ratios natural - 12:3 having received cold treatment, 1:4 not having received & treatment.8 A bioequivalence sinus 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 remedy demonstrated allergic rhinitis received with the cyanocobalamin (or placebo) containing lozenge twice daily for 21 consecutive natural days. All subjects also cold 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) use. In sinus and remedy the post-treatment period, the active group natural (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 cold and & group compared to sinus the placebo for weeks remedy 2, 6, 8 and 9. The results tend to replicate those of the studies on injectable cyanocobalamin.10 In 1990 study natural in San cold Diego, CA the & 5 active subjects with allergic rhinitis had a lowered total serum IgE from Day 0 to Day 90 while 4 placebo subjects, (2 with allergic rhinitis, 1 with asthma sinus and 1 with both), had flat or increased IgE levels.4 In a randomized, double-blind, placebo controlled study of symptoms and serum IgE remedy levels in San Diego, CA in mid-1991, subjects had allergic rhinitis and/or asthma. Serum was drawn at Day 0 and Day 30. Seven of the 10 active treated natural subjects had a reduction in total serum IgE levels. cold In 10 placebo & treated subjects, 5 had levels of total serum IgE that stayed the same (plus or minus 5%), 3 decreased and 2 increased.5 sinus Statistical analysis of the open-label study as well as remedy the double-blind randomized placebo controlled study have shown a significant effect of vitamin B12 in lowering serum IgE concentrations.
