Drug intolerance or drug sensitivity refers to an inability to tolerate the adverse effects of a medication, generally at therapeutic or subtherapeutic doses. Conversely, a patient is said to be "tolerating" a drug when they can tolerate its adverse effects.
For example, a person who developed an allergy to a red dye will be allergic to any new drug which contains that red dye. A drug allergy is different from an intolerance. A drug intolerance, which is often a milder, non-immune-mediated reaction, does not depend on prior exposure.
Hypersensitivity (also called hypersensitivity reaction or intolerance) is an abnormal physiological condition in which there is an undesirable and adverse immune response to antigen. It is an abnormality in the immune system that causes immune diseases including allergies and autoimmunity.
While pseudoallergy and IgE-mediated allergy share some similarities in their clinical manifestations, pseudoallergy is not the same as common allergy or type 1 reactions. Pseudoallergy can be caused by a variety of medications through various pathways.
Allergies, also known as allergic diseases, are various conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis.
Drug tolerance or drug insensitivity is a pharmacological concept describing subjects' reduced reaction to a drug following its repeated use. Increasing its dosage may re-amplify the drug's effects; however, this may accelerate tolerance, further reducing the drug's effects.
Food intolerance is more chronic, less acute, less obvious in its presentation, and often more difficult to diagnose than a food allergy. Symptoms of food intolerance vary greatly, and can be mistaken for the symptoms of a food allergy.
Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for environmental allergies, such as insect bites, and asthma. [1] [2] Immunotherapy involves exposing people to larger and larger amounts of allergens in an attempt to change the immune system's response.
Repeated administration of antibiotics, which can form haptens to cause allergic reactions, can also reduce antibiotic allergies in children. The tumor microenvironment. Immune tolerance is an important means by which growing tumors, which have mutated proteins and altered antigen expression, prevent elimination by the host immune system.
Salicylate intolerance is a form of food intolerance or of drug intolerance. Salicylate sensitivity is a pharmacological reaction, not a true IgE -mediated allergy . However, it is possible for aspirin to trigger non-allergic hypersensitivity reactions.
