A MANUAL ON DRUG ALLERGY - A COMPREHENSIVE REVIEW

Muhammed Rashid A. K.*

ABSTRACT

All drugs have the potential to cause side effects, also known as 'adverse drug reactions', but not all of these are allergic in nature .A drug allergy, or an allergic drug reaction, is a type B adverse drug reaction that results from a specific immunologic response to a medication. Allergic drug reactions account for about 6 to 10 percent of all adverse drug reactions, but up to 10 percent of fatal reactions. IgE, IgG, can mediate immunologic drug reactions or by lymphocytes. Drug-specific immune responses depend on host factors and on the chemical structure and metabolism of the drug.
