A recent study uncovers a startling finding: Commonly prescribed antihistamines may be putting elderly patients at risk!
An in-depth analysis published in the Journal of the American Geriatrics Society has shed light on a potential danger lurking in hospitals. Researchers discovered that older patients admitted to doctors who frequently prescribe first-generation antihistamines are at a significantly higher risk of developing delirium during their hospital stay. But here's where it gets controversial—these medications are widely used, yet their impact on this vulnerable population is often overlooked.
First-generation antihistamines, including the well-known diphenhydramine (Benadryl), are a double-edged sword. While they are effective in treating histamine-related issues like hives and anaphylaxis, they can also cause harm, especially in older adults. The study analyzed data from a large cohort of patients aged 65 and above, admitted to multiple hospitals in Ontario, Canada, between 2015 and 2022. The results were eye-opening: 34.8% of these patients experienced delirium, a state of acute confusion and altered mental status.
The risk was not evenly distributed. Patients admitted to physicians with a higher tendency to prescribe first-generation antihistamines were 41% more likely to suffer from delirium compared to those whose doctors rarely prescribed these medications. This finding suggests that the choice of antihistamine can have a profound impact on patient outcomes.
And this is the part most people miss—the study's implications reach beyond the hospital walls. It serves as a wake-up call for healthcare professionals, urging them to exercise caution when prescribing sedating antihistamines to older patients. As Dr. Aaron M. Drucker, the study's corresponding author, emphasizes, these medications should be used judiciously to prevent potential harm.
This research adds to the growing body of evidence highlighting the delicate balance between medication benefits and risks. It raises questions about the appropriate use of first-generation antihistamines and the need for alternative treatment options for older patients. Could this study prompt a shift in prescribing practices? The answer may lie in the hands of healthcare providers and the decisions they make for their patients.
