A drug allergy is an allergy to a drug, most commonly a medication, and is a form of adverse drug reaction. Medical attention should be sought immediately if an allergic reaction is suspected. An allergic reaction will not occur on the first exposure to a substance.
Commonly used anti-allergic agents include antihistamines, decongestants, corticosteroids, leukotriene pathway modifiers and mast cell stabilizers. Antihistamines and decongestants are generally the first-line treatment in mild to moderate allergic reactions. Corticosteroids are generally indicated for moderate cases.
The symptoms of DRESS syndrome usually begin 2 to 6 weeks but uncommonly up to 8–16 weeks after exposure to an offending drug. Symptoms generally include fever, an often itchy rash which may be morbilliform or consist mainly of macules or plaques, facial edema (i.e. swelling, which is a hallmark of the disease), enlarged and sometimes painful lymph nodes, and other symptoms due to ...
The classification organizes the hypersensitivity reactions to NSAIDs into the following five categories: NSAIDs-exacerbated respiratory disease (NERD) is an acute (immediate to several hours) exacerbation of bronchoconstriction and other symptoms of asthma in individuals with a history of asthma and/or nasal congestion, rhinorrhea or other symptoms of rhinitis and sinusitis in individuals ...
About 90% of these adverse reactions take the form of benign morbilliform rash hypersensitivity drug reactions such as MPR. However, they also include more serious reactions: Pseudo-allergic reactions in which a drug directly stimulates mast cells, basophils, and/or eosinophils to release pro-allergic mediators (e.g. histamine);
Enzyme potentiated desensitization (EPD), is a treatment for allergies developed in the 1960s by Dr. Leonard M. McEwen in the United Kingdom.EPD uses much lower doses of antigens than conventional desensitization treatment paired with the enzyme β-glucuronidase.
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.
The goals in this area are finding a cure for HIV-infected individuals; developing preventive strategies, including vaccines and treatment as prevention; developing therapeutic strategies for preventing and treating co-infections such as TB and hepatitis C in HIV-infected individuals; and addressing the long-term consequences of HIV treatment.
