Although complications during anesthesia are rare, potentially life-threatening consequences may occur if an anaphylactic reaction develops. The severity of the reaction whilst under anesthesia is because the anesthetist is only made aware of the allergy when it is severe enough to compromise the cardiovascular system and the respiratory system.
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 ...
An enlarged prostate is common in older men and typically carries symptoms of lower urinary tract problems, which can become bladder problems over time. Tadalafil is typically taken daily for BPH.
Injection site reactions (ISRs) are reactions that occur at the site of injection of a drug. They may be mild or severe and may or may not require medical intervention. Some reactions may appear immediately after injection, and some may be delayed. [1] Such reactions can occur with subcutaneous, intramuscular, or intravenous administration.
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
An allergic transfusion reaction is when a blood transfusion results in allergic reaction. It is among the most common transfusion reactions to occur. Reported rates depend on the degree of active surveillance versus passing reporting to the blood bank. [1] [2] Overall, they are estimated to complicate up to 3% of all transfusions. [3]
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 ...
Histamine, the structure shown, causes a person to feel itchy during an allergic reaction. Conditions caused by food allergies are classified into three groups according to the mechanism of the allergic response: [56] IgE-mediated (classic) – the most common type, occurs shortly after eating and may involve anaphylaxis.
