Epinephrine autoinjectors are portable single-dose epinephrine-dispensing devices used to treat anaphylaxis. Epinephrine (adrenaline) is the first-line treatment for severe allergic reactions (anaphylaxis). If administered in a timely manner, epinephrine can reverse its effects. Epinephrine relieves airway swelling and obstruction, and improves ...
Epinephrine, also known as adrenaline, is a medication and hormone. [10] [11] As a medication, it is used to treat several conditions, including anaphylaxis, cardiac arrest, asthma, and superficial bleeding. [8] Inhaled epinephrine may be used to improve the symptoms of croup. [12] It may also be used for asthma when other treatments are not ...
Anaphylactoid reaction, non-immune anaphylaxis, or pseudoanaphylaxis, is a type of anaphylaxis that does not involve an allergic reaction but is due to direct mast cell degranulation. [ 10 ] [ 42 ] Non-immune anaphylaxis is the current term, as of 2018, used by the World Allergy Organization [ 42 ] with some recommending that the old ...
The treatment of immediate hypersensitivity reactions includes the management of anaphylaxis with intramuscular adrenaline (epinephrine), oxygen, intravenous (IV) antihistamine, support blood pressure with IV fluids, avoid latex gloves and equipment in patients who are allergic, and surgical procedures such as tracheotomy if there is severe ...
When these symptoms occur the allergic reaction is called anaphylaxis. [1] Anaphylaxis occurs when IgE antibodies are involved, and areas of the body that are not in direct contact with the food become affected and show severe symptoms. [1] [21] Untreated, this can proceed to vasodilation and a low blood pressure situation called anaphylactic ...
Persons with a history of severe anaphylactic reaction may carry an injectable emergency dose of epinephrine (such as an EpiPen). Oral steroids may also be helpful. Allergy immunotherapy has been reported to improve or cure OAS in some patients. Immunotherapy with extracts containing birch pollen may benefit those with apple or hazelnut related ...
In allergic ACS, blocking beta receptors while giving epinephrine (which is the basis of treatment of anaphylaxis) can lead to an unopposed activity of α-adrenergic receptors which would aggravate the coronary spasm. Also opioids, indicated to relieve chest pain, may induce massive mast cell degranulation which in turn will worsen the anaphylaxis.
An epinephrine autoinjector (or adrenaline autoinjector, also known by the trademark EpiPen) is a medical device for injecting a measured dose or doses of epinephrine (adrenaline) by means of autoinjector technology. It is most often used for the treatment of anaphylaxis. The first epinephrine autoinjector was brought to market in 1983.
