Hello, Welcome to icliniq.com. I understand your concern. Cutaneous allergic reactions (hives, rashes, urticaria) alone—if not associated with systemic symptoms (such as difficulty breathing, hypotension, facial, laryngeal swelling, or signs of anaphylaxis)—are not absolute contraindications to anesthesia or surgery. The anesthesiologist's key concern is the risk of progression to a more severe reaction, especially under the stress of surgery or from exposure to other medications or agents used in the perioperative period. Your situation involves ongoing hypersensitivity reactions to both Methimazole and PTU (Propylthiouracil).
