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.
Drug intolerance. 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. Some instances of drug intolerance are known to result from genetic ...
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.
Aspirin-exacerbated respiratory disease ( AERD ), also called NSAID-exacerbated respiratory disease ( N-ERD) or historically aspirin-induced asthma and Samter's Triad, is a long-term disease defined by three simultaneous symptoms: asthma, chronic rhinosinusitis with nasal polyps, and intolerance of aspirin and other nonsteroidal anti ...
Multiple chemical sensitivity ( MCS ), also known as idiopathic environmental intolerances ( IEI ), is an unrecognized and controversial diagnosis characterized by chronic symptoms attributed to exposure to low levels of commonly used chemicals. [1] [2] Symptoms are typically vague and non-specific. They may include fatigue, headaches, nausea ...
Idiosyncratic drug reactions, also known as type B reactions, are drug reactions that occur rarely and unpredictably amongst the population. This is not to be mistaken with idiopathic , which implies that the cause is not known.
Allergic contact dermatitis (ACD) is a form of contact dermatitis that is the manifestation of an allergic response caused by contact with a substance; the other type being irritant contact dermatitis (ICD). Although less common than ICD, ACD is accepted to be the most prevalent form of immunotoxicity found in humans.
Mast cell activation was assigned an ICD-10 code (D89.40, along with subtype codes D89.41-43 and D89.49) in October 2016. [19] According to the American Academy of Allergy, Asthma, and Immunology (AAAI), the most precise method of diagnosing MCAS is through a bone marrow biopsy and aspirate. [17]
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.
Anaphylaxis (Greek: ana- ‘again’ + phulaxis ‘guarding’) is a serious, potentially fatal allergic reaction and medical emergency that is rapid in onset and requires immediate medical attention regardless of the use of emergency medication on site. [4] [5] It typically causes more than one of the following: an itchy rash, throat closing ...
