ASA Desensitization in Pregnancy

According to published estimates, the prevalence of an NSAID allergy (hypersensitivity) in the general population is estimated to be between 0.5% and 2%, with some studies reporting a range of 1-3% of people experiencing a reaction to NSAIDs; however, this rate can be significantly higher in individuals with conditions like asthma, nasal polyps, or chronic urticaria, where it may reach up to 20-30%. Genetic and epigenetic backgrounds are implicated in various processes of NSAID-induced hypersensitivity reactions. Aspirin is a type of NSAID and may result in some cross sensitivity in NSAID allergic people. Well, as low dose aspirin is currently the only pharmacological recommended prophylactic agent for HDP, what can we do for these patients? In a new publication (ahead of print, 2/17/2025), clinicians from Singapore provide helpful insights- and an easy to adopt protocol- for aspirin desensitization in pregnancy. Listen in for details.
