Social media platforms have become breeding grounds for allergy and immunology misinformation, with most user comments either supporting or remaining neutral toward false claims, according to a new study published in The Journal of Allergy and Clinical Immunology: In Practice.
Researchers from Milwaukee found that 62% of top comments on social media posts containing allergy misinformation were either supportive or neutral, suggesting a troubling lack of critical evaluation among users consuming health information online.
“Patients are arriving in clinic already influenced by what they’ve seen on social media,” explained lead author Samira Jeimy, MD, PhD, FRCPC. “We found that the most engaging allergy/immunology social media content is often the least accurate, especially those around natural remedies and IgG testing. Understanding these patterns helps us meet patients where they are and respond more effectively.”
The cross-sectional analysis examined 347 publicly available posts across TikTok, Facebook, Instagram, and X (formerly Twitter) from January to March 2025. Researchers focused on posts with more than 500 interactions, identifying content with “demonstrably false or misleading claims” that contradicted established medical guidelines from authoritative allergy and immunology organizations.
Five primary categories of misinformation emerged from the analysis. Natural and alternative cures topped the list, appearing in 31% of the examined posts. These typically promoted unproven remedies like certain herbs, special diets, or alternative treatments as cures for allergies without scientific evidence.
The second most common category was IgG testing endorsement, appearing in 24% of posts. IgG tests are controversial in the medical community, as they often lead to unnecessary food restrictions when misinterpreted as definitive allergy diagnostics rather than what they actually measure—exposure to foods.
Medication fear-mongering ranked third at 18%, with posts often exaggerating side effects of standard allergy medications or suggesting they cause long-term harm. Food allergy misrepresentation and pharmaceutical conspiracy theories made up the remainder of the misinformation categories.
The research revealed notable platform differences as well. Conspiracy theories about the pharmaceutical industry were most prevalent on X and Facebook, accounting for 19% and 17% of the examined posts on those platforms respectively. These posts typically alleged collusion between doctors and pharmaceutical companies to suppress “natural cures” for allergies.
Of particular concern to healthcare providers was the response to this misinformation. Among 3,470 top comments analyzed, 2,151 (62%) were either supportive of the misinformation or neutral, while only 1,319 (38%) challenged the false claims.
The findings come amid growing concern in the medical community about the impact of social media on patient care. Allergists and immunologists increasingly report patients arriving with preconceived notions based on information from platforms like TikTok and Instagram, often making clinical conversations more challenging.
Dr. Ellen Soffin, an allergist not involved in the study, commented: “We’re seeing a real disconnect between what patients believe about allergies based on their social media consumption and what the evidence actually shows. This research quantifies what many of us are experiencing in practice.”
The public health implications could be significant. Patients following unproven remedies might delay seeking proper medical care or abandon effective treatments based on misinformation. For conditions like severe food allergies or asthma, such decisions could have life-threatening consequences.
Healthcare organizations are now examining ways to counter this trend, including more robust social media presence from credible medical sources and better patient education materials specifically addressing common misconceptions seen online.
The researchers emphasized that understanding these patterns of misinformation is crucial for developing effective strategies to provide accurate information to patients and support critical patient education efforts in an increasingly complex digital information landscape.
