The misattribution of an adverse drug reaction (ADR) as a symptom or illness can lead to the prescribing of additional medication, referred to as a prescribing cascade. The aim of this systematic review is to identify published prescribing cascades in community‐dwelling adults. A systematic review was reported in line with the PRISMA guidelines and pre‐registered with PROSPERO. Electronic databases (Medline [Ovid], EMBASE, PsycINFO, CINAHL, Cochrane Library) and grey literature sources were searched. Inclusion criteria: community‐dwelling adults; risk‐prescription medication; outcomes‐initiation of new medicine to “treat” or reduce ADR risk; study type‐cohort, cross‐sectional, case‐control, and case‐series studies. Title/abstract screening, full‐text screening, data extraction, and methodological quality assessment were conducted independently in duplicate. A narrative synthesis was conducted. A total of 101 studies (reported in 103 publications) were included. Study sample sizes ranged from 126 to 11 593 989 participants and 15 studies examined older adults specifically (≥60 years). Seventy‐eight of 101 studies reported a potential prescribing cascade including calcium channel blockers to loop diuretic ( n = 5), amiodarone to levothyroxine ( n = 5), inhaled corticosteroid to topical antifungal ( n = 4), antipsychotic to anti‐Parkinson drug ( n = 4), and acetylcholinesterase inhibitor to urinary incontinence drugs ( n = 4). Identified prescribing cascades occurred within three months to one year following initial medication. Methodological quality varied across included studies. Prescribing cascades occur for a broad range of medications. ADRs should be included in the differential diagnosis for patients presenting with new symptoms, particularly older adults and those who started a new medication in the preceding 12 months.
