But a new analysis suggests that this treatment offers little benefit \u2014 and in some cases, may increase risk of cognitive and other side effects.<\/p>\n<p>The <a href=\"https:\/\/doi.org\/10.1136\/bmj-2026-100163\" style=\"text-decoration:underline\" target=\"_blank\" rel=\"nofollow noopener\">analysis<\/a>, published online July 29, 2026, by The BMJ, involved a review of 47 clinical trials involving over 6,200 children and adults (ages 1 to 43, 52% female), most of whom had \u00a0moderate to severe atopic dermatitis. The researchers evaluated the effectiveness of oral antihistamines and other medications in easing symptoms like itching and difficulty sleeping.<\/p>\n<p>Although antihistamines produced some improvements, most were far too minor to be noticeable \u2014 and the drugs didn\u2019t appear to reduce the frequency of eczema flare-ups. Specifically, older \u201cfirst generation\u201d antihistamines like diphenhydramine (Benadryl) and newer \u201csecond generation\u201d nonsedating antihistamines like loratadine (Claritin) reduced doctor-scored skin signs of eczema severity by only 1.87 points on an 83-point scale \u2014 far short of the 8.2-point change needed before patients would notice symptom relief. Itch scores (reported by patients or caregivers) improved by less than 1 point on a 10-point scale, versus the 3-point threshold considered meaningful.<\/p>\n<p>Safety was a bigger concern. First-generation antihistamines caused roughly 66 additional cases of cognitive impairment per 1,000 patients \u2014 including confusion and memory problems \u2014 and higher rates of stopping treatment due to side effects. Among the second-generation options, effects varied: loratadine wasn\u2019t linked to cognitive impairment, while cetirizine and levocetirizine (Xyzal) carried slightly increased risk.<\/p>\n<p>The authors recommended against routine use of antihistamines for eczema, as they\u2019re unlikely to help much and may carry unnecessary risks. Moisturizers and topical anti-inflammatories remain better initial choices for treating eczema, but antihistamines may still be a reasonable option for patients with other allergic conditions like hives or hay fever.<\/p>\n<p>&#13;<br \/>\n          &#13;<br \/>\n            Image: \u00a9 Viktoriya Skorikova\/Getty Images&#13;<br \/>\n          &#13;\n        <\/p>\n","protected":false},"excerpt":{"rendered":"&#13; &#13; Nearly half of people living with atopic dermatitis (eczema) in the United States turn to oral&hellip;\n","protected":false},"author":2,"featured_media":862596,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[33],"tags":[64,63,56935,56938,56933,56934,56937,56939,137,56928,3726,56932,56931,56930,56936,56929,490],"class_list":["post-862595","post","type-post","status-publish","format-standard","has-post-thumbnail","category-medication","tag-au","tag-australia","tag-harvard-health","tag-harvard-health-letter","tag-harvard-health-publications","tag-harvard-health-publishing","tag-harvard-heart-letter","tag-harvard-women","tag-health","tag-health-information","tag-health-news","tag-health-newsletter","tag-health-newsletters","tag-health-report","tag-health-harvard-edu","tag-medical-information","tag-medication"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/862595","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=862595"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/862595\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/862596"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=862595"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=862595"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=862595"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
