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 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.

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 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 sleepiness.

Topical nasal steroids Topical nasal steroids are anti-inflammatory drugs that stop the allergic reaction. In addition to other beneficial actions, they reduce the number of mast cells in the nose and reduce mucus secretion and nasal swelling. The combination of antihistamines and nasal steroids is a very effective way to treat allergic rhinitis. This medication should not be confused with anabolic steroids that have serious side effects. Cromolyn sodium Cromolyn sodium stops allergic reactions from starting. It is administered as a nasal spray, and it can prevent the release of chemicals like histamine from the mast cell.
