| Drug Class | Examples | Reason |
|---|---|---|
| Beta-blockers | Metoprolol, atenolol, carvedilol | Prevent rebound tachycardia/hypertension; abrupt withdrawal can trigger MI |
| Calcium channel blockers | Amlodipine, diltiazem, verapamil | Hemodynamic stability |
| Alpha-2 agonists | Clonidine, methyldopa | Avoid rebound hypertensive crisis |
| Alpha-1 blockers | Tamsulosin, doxazosin | Hemodynamic stability |
| Antiarrhythmics | Amiodarone, digoxin, sotalol | Continuous rhythm control needed |
| Nitrates/Vasodilators | Nitroglycerin, isosorbide, hydralazine | Cardiac protection |
| Statins | Atorvastatin, rosuvastatin | Pleiotropic cardioprotective effect; abrupt withdrawal harmful |
| Aspirin (cardiac indications) | Low-dose aspirin | Continue if history of CAD/stents; stop only for neuro/ophthalmic/spine surgery |
| Antiepileptics (AEDs) | Levetiracetam, valproate, phenytoin | Prevent perioperative seizures; IV alternatives available |
| Antiparkinson drugs | Levodopa/carbidopa, entacapone | Abrupt withdrawal risks NMS-like syndrome; give up to time of surgery |
| Antipsychotics | Haloperidol, risperidone, olanzapine | Prevent psychosis and agitation postop |
| Anxiolytics/Benzodiazepines | Alprazolam, clonazepam, lorazepam | Prevents anxiety and withdrawal; also used as premeds |
| Inhaled bronchodilators | Salbutamol, ipratropium, tiotropium, salmeterol | Reduces perioperative bronchospasm and pulmonary complications |
| Inhaled corticosteroids | Fluticasone, budesonide | Reduces airway reactivity |
| Systemic steroids | Prednisolone | Avoid adrenal insufficiency; give stress-dose steroids if on long-term use |
| Thyroid medications | Levothyroxine | Long half-life (7 days), but continue for stability |
| Antiretrovirals | Tenofovir, efavirenz, lamivudine | Resistance develops quickly with missed doses |
| Antivirals | Acyclovir, valacyclovir | Continue for immunosuppressed patients |
| Long-acting opioids | MS Contin, oxycontin (in chronic pain patients) | Prevent acute withdrawal; for major surgery, convert to IV background infusion if NPO >8 hrs (Miller's Anesthesia, 10e, Box 47.2) |
| Ophthalmic drops | Pilocarpine, timolol eye drops | Continue (absorbed minimally, topical use) |
| Immunosuppressants | Tacrolimus, cyclosporine (transplant patients) | Transplant rejection risk; check levels |
| Non-biologic DMARDs | Methotrexate, hydroxychloroquine, sulfasalazine | Generally continue (rheumatoid arthritis, IBD) |
| Drug Class | Reason |
|---|---|
| ACE inhibitors / ARBs | Risk of refractory intraoperative hypotension; hold morning dose (unless heart failure or uncontrolled HTN) |
| Diuretics (furosemide, HCTZ) | Risk of hypovolemia and hypokalemia |
| Metformin | Risk of lactic acidosis, especially if contrast used or prolonged NPO |
| SGLT-2 inhibitors (empagliflozin, dapagliflozin) | Risk of euglycemic DKA; hold 3-4 days before |
| Insulin | Adjust - give reduced dose (50-75% of basal); hold prandial doses |
| Sulfonylureas (glipizide, glibenclamide) | Risk of hypoglycemia while NPO |
| Oral hypoglycemics (most) | Hold; resume when eating |
| NSAIDs | Typically hold 24-72 hrs preop (bleeding risk, AKI risk) |
| Biologic DMARDs (adalimumab, etanercept, infliximab) | Infection risk, impaired wound healing; hold for one dosing cycle |
| JAK inhibitors (tofacitinib, baricitinib) | Hold ≥3 days prior |
| Oral anticoagulants (warfarin, rivaroxaban, apixaban, dabigatran) | Bleeding risk; managed per bridging protocols |
| MAOIs | Drug interactions with anesthetics; consult anesthesia |
| GLP-1 agonists (semaglutide, liraglutide) | Delayed gastric emptying, increased aspiration risk; hold 1 week prior |
| Estrogen/HRT | Thromboembolism risk; stop ~4 weeks before major surgery |
| Bisphosphonates | Routinely held day of surgery |
What about cilastozol and sodium bicarbonate?
cilostazol hold before surgery perioperative antiplatelet guidelines
sodium bicarbonate premedication day of surgery NPO aspiration prophylaxis anesthesia
| Guideline Source | Recommendation |
|---|---|
| Froedtert / Most US guidelines | Hold at least 5 days before surgery |
| NHS Scotland / UK guidelines | Hold 7 days before surgery |
| Chesapeake Regional guidelines | Hold 4 days preop |
| UKCPA Handbook | Manufacturer recommends 5-day cessation; for ophthalmology, 3 days may be sufficient (t½ = 10.5-13 hrs) |
