The expanding roles and popularity of glucagon-like peptide-1 (GLP-1) and GLP-1/glucose-dependent insulinotropic polypeptide (GIP) receptor agonists has created access barriers to medication use. We sought to describe an adverse drug event which occurred after reinitiation of a GLP-1 receptor agonist following a prolonged lapse in therapy due to poor medication access.: Once-weekly injectable semaglutide was prescribed to an outpatient 33-year-old male for chronic weight management. After a delayed initiation due to global shortage, semaglutide was initiated and titrated over five months before a seven week lapse in therapy due to prior authorization interruption. Despite the extended treatment gap, the patient was directed to reinitiate semaglutide at the target dose rather than starting dose, which was followed by recurrent, symptomatic nausea and vomiting requiring medical intervention.A prolonged lapse in GLP-1 receptor agonist therapy, typically defined as missing three or more doses of a once-weekly injectable, warrants consideration of reinitiation at a reduced dose, personalized to the patient's prior gastrointestinal tolerability, efficacy goals, and therapy lapse duration. Therapy lapses with GLP-1 receptor agonists may be prevented by utilizing a multi-modal approach including extended dosing intervals, intermediate doses, agent interchange, efficient prior authorization communication, and cautious initiation of GLP-1 recent agonists while supply cannot meet demand.
