Allergy and Antihistamines and surgery: what to do before and after
Surgery raises specific medication-management questions, and getting the answer right matters because both unintended drug interactions during anaesthesia and abrupt discontinuation of important chronic therapies carry risk. Whether Allergy and Antihistamines (Allergy and Antihistamines) needs to be stopped before surgery, continued through, or paused for a defined window depends on Cetirizine, Fexofenadine, Loratadine and the type of procedure.
Before-surgery decision
For most chronic medications including many Allergy and Antihistamines agents, the surgical team or anaesthetist makes the stop-or-continue decision during pre-op assessment. Considerations include bleeding risk, anaesthesia interactions, the urgency of the underlying condition and the type of procedure. According to most guidelines, surprises are avoided by listing all medications including Allergy and Antihistamines at 30mg, 60mg, 120mg, 180mg, 5mg on the pre-op form.
After surgery
Post-operative resumption of Allergy and Antihistamines depends on the surgical course, the medication's impact on recovery (e.g. wound healing, gastric tolerance, mobility) and any new prescriptions added after surgery. Pharmacological options include second-generation oral antihistamines such as cetirizine, loratadine and fexofenadine, which block the H1 histamine receptor with limited sedation; intranasal corticosteroids for rhinitis… Resuming on schedule is usually the goal as soon as oral intake and clinical stability allow.
