Your team's written list is the only list that matters: the NHS says you will be told clearly whether to stop your usual medicines before hospital.
The usual adjust-or-stop candidates: anticoagulants and antiplatelets, since some must stop to prevent heavy bleeding, though some like stent aspirin may deliberately continue; diabetes medicines while fasting; GLP-1 drugs that slow stomach emptying; some antidepressants; and herbal supplements, which must be declared. Usually continued: blood pressure medicines with a small sip of water, and inhalers. Bring the full list, including supplements, to pre-op, follow the written plan exactly, and never improvise either direction.
What to do
Common questions
What medications should I stop before surgery?
The honest answer is that your surgical team's list is the only list that matters, and the NHS says you will be given clear information on whether you should stop taking your usual medicines before going into hospital, which is why the pre-operative assessment exists. The drugs that usually make the stop-or-adjust list: anticoagulants and antiplatelets, with NHS hospital guidance noting some blood-thinning medications must be stopped before an operation because they can make you bleed a lot, though some, like aspirin for a stent, may be deliberately continued, so never decide this one yourself; diabetes medicines, which change because you will be fasting; GLP-1 weight-loss and diabetes drugs, which slow stomach emptying and matter for anesthesia; some antidepressants and MAOIs, flagged to the anesthetist; and herbal supplements, which the NHS counts as things to declare, since several affect bleeding and anesthesia. The drugs usually continued: blood pressure medicines, often with a small sip of water, and inhalers. The safe behaviors: bring the full list, medicines, vitamins, herbal supplements, to the pre-op assessment, per the NHS; follow the written instructions exactly; and never improvise stops or continuations, because both directions carry real risk.
