Vitamin D3 solution was administered totally 30 drop (4000 IU)/day (1 drop:133.33 IU of 3333 IU/mL) dose of colecalciferol (Devit-3®, DEVA-Türkiye, 15 mL/50,000 IU, 1 mL = 25 drop) at 15-minutes intervals without premedication.</div></div><div><h3>Results</h3><div>The patient group consisted of 16 female subjects (89%); the mean age was 46 ± 12 years. When the patients were evaluated in terms of the risk of hypersensitivity reactions according to their clinical history, 5 patients had a history of anaphylaxis with vitamin D preparations (colecalciferol oral drop, n = 3; colecalciferol capsule, n = 2), and 13 patients had a history of HSRs other than anaphylaxis with isolated cutaneous reactions (pruritus, flushing, urticaria and angioedema) (n = 11, colecalciferol oral drop; n = 2, colecalciferol capsule). Skin prick test (SPT) and intradermal test (IDT) were performed on 9 patients. SPTs and IDTs were negative in all patients. Urticaria occur during desensitization in only one patient but vitamin D replacement was performed within the following 48–72 h after HSRs. All other patients tolerated 30 drop (4000 IU) and have continued to take same dose every day for the last 6 weeks with no adverse reactions.</div></div><div><h3>Conclusion</h3><div>Desensitization with oral vitamin D preparations has a crucial role for patients who can not receive vitamin D supplements by other ways. Vitamin D drop forms, which are better absorbed than capsule forms which contains the lowest units per/mL without the need to dilute the preparation, not contain any additives with HSRs potential such as gelatin and peanut oil are good option. Our 6-step desensitization protocol with oral drop of colecalciferol is a reliable protocol in patients with a history of vitamin D HSR","PeriodicalId":54295,"journal":{"name":"World Allergy Organization Journal","volume":"18 2","pages":"Article 101029"},"PeriodicalIF":3.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143179817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
