Urticaria and pruritus = MAST CELL mediated, which is treated like a standard allergicreaction.

The STREAM-1 trial found that for [2] patients with STEMI presenting within 3 hours of symptom onset and unable to attain PCI within 1 hour of first medical contact, a pharmaco-invasive strategy resulted in similar rates of death, shock, heart failure, or reinfarction compared to primary PCI.
Hypersensitivity reaction to a GLP-1 agonist, type 1 diabetes mellitus, and pregnancy. Hypersensitivity/dermatologic: GLP-1 agonists are synthetic peptides; may lead to antibody formation and allergicreaction/injection site reaction. Reactions are usually minor: transient warmth, pruritis at injection site that resolves.
Background: Diphenhydramine, a first-generation antihistamine, is the most common pharmacologic agent used to treat acute allergicreactions. Article: Abella BS et al. Moreover, the FDA approved intravenous (IV) cetirizine to treat acute urticaria in 2019. Ann Emerg Med 2020. in the IV cetirizine group and 2.1
The overall incidence of biphasic reactions is unknown with rates quoted from < 0.5% This varied incidence can be due to inconsistent definitions or inclusion of mild reactions. Since half of biphasic reactions occur within the first 6-12 hrs ( Lee 2014 ) physicians often choose an observation time of 4-6 hrs. Read More: 1.
