Which Medications to Stop Before Cosmetic Surgery Abroad

Most blood thinners, anti-inflammatories and herbal supplements need to be stopped one to two weeks before cosmetic surgery, and the exact interval depends on the drug, not the operation. Clopidogrel is typically stopped seven days before non-cardiac surgery (UK Clinical Pharmacy Association Handbook of Perioperative Medicines). Never stop a prescribed medicine on your own — the stop decision belongs to the prescriber.

Key facts

The UK Clinical Pharmacy Association's Handbook of Perioperative Medicines advises stopping clopidogrel seven days before non-cardiac surgery, including the dose on the morning of surgery, and shortening that to five days only where thrombotic risk is high.

UT Southwestern Medical Center advises pausing common blood thinners and anti-inflammatories one to two weeks before surgery, and skipping listed supplements for at least seven days.

The supplements UT Southwestern names to stop include vitamin E, garlic, ginkgo, ginseng, St John's wort, echinacea, ephedra, kava, valerian and CBD oil.

Combined hormonal contraception should be considered for stopping four weeks before major elective surgery where prolonged immobilisation is likely, with a progestogen-only alternative substituted — UKCPA guidance. Pregnancy must be excluded on admission.

GLP-1 drugs are the widely misreported case: the October 2024 multi-society guidance led by the American Society of Anesthesiologists recommends most patients continue them before elective surgery, not stop them.

Bring a written list of every prescription, over-the-counter drug and supplement you take, with doses, to your pre-operative consultation. A verbal "nothing much" is the most common cause of a cancelled operation on the day.

Which medications need to be stopped before cosmetic surgery?

The medicines that matter fall into four groups, and they behave differently. Drugs that thin the blood raise bleeding and haematoma risk. Drugs that affect stomach emptying raise the risk of aspiration under anaesthesia. Drugs that raise clotting risk matter because of the flight home. And drugs that interact with anaesthetic agents matter in theatre.

Antiplatelets and anticoagulants are the first group: warfarin, clopidogrel, apixaban, rivaroxaban, aspirin taken regularly, and the over-the-counter anti-inflammatories such as ibuprofen and naproxen. The UK Clinical Pharmacy Association's Handbook of Perioperative Medicines gives clopidogrel a seven-day stop before non-cardiac surgery, including the morning dose, with five days considered only where the thrombotic risk is high and cardiac surgery handled by a multidisciplinary team rather than a fixed rule.

The critical caveat: if you take an antiplatelet because you have a coronary stent, stopping it can be more dangerous than the bleeding it prevents. That decision belongs to your cardiologist, and a cosmetic operation is not a reason to override it.

UT Southwestern Medical Center's pre-operative guidance, published February 2022, asks patients to stop common blood thinners and anti-inflammatories one to two weeks before surgery, and lists warfarin, heparin, rivaroxaban, apixaban, clopidogrel, aspirin and ibuprofen among them.

Which supplements do surgeons ask you to stop?

Herbal and vitamin supplements are the category patients most often forget to declare, on the assumption that "natural" means inert before surgery. It does not. Several affect platelet function or interact with anaesthetic drugs.

UT Southwestern names ten to stop: vitamin E, garlic, ginkgo, ginseng, St John's wort, echinacea, ephedra, kava, valerian and CBD oil, and advises skipping them for at least seven days before surgery. Fish oil and high-dose turmeric are commonly added to that list by surgical teams for the same platelet reason, though they are not named in that particular guidance.

St John's wort deserves separate mention because its problem is not bleeding: it induces liver enzymes that change how a range of other drugs, including some anaesthetic and analgesic agents, are metabolised. It is one of the few supplements where a longer stop interval is often requested.

Do you have to stop Ozempic or Mounjaro before surgery?

Probably not — and this is where most travel-clinic advice on the internet is out of date. In October 2024 the American Society of Anesthesiologists, together with the American Gastroenterological Association, the American Society for Metabolic and Bariatric Surgery, the International Society of Perioperative Care of Patients with Obesity and SAGES, issued multi-society guidance recommending that most patients continue GLP-1 receptor agonists before elective surgery rather than stopping them.

The guidance replaces blanket discontinuation with individual risk assessment. Patients judged highest risk — those in the dose-escalation phase, typically the first four to eight weeks, those on higher doses, and those with active nausea, vomiting, abdominal pain or constipation — are advised to follow a liquid-only diet for 24 hours before surgery to reduce the risk of delayed gastric emptying and aspiration. The societies also warn that withholding the drug carries its own risk of raised blood sugar.

The practical implication for a patient travelling to Istanbul: declare the drug, the dose and where you are in the escalation schedule at the consultation, and expect a fasting or liquid-diet instruction rather than an instruction to stop. Do not stop it unprompted because a forum told you to.

What about the contraceptive pill and HRT?

The UK Clinical Pharmacy Association's handbook advises considering stopping combined hormonal contraception four weeks before major elective surgery where prolonged immobilisation is likely, and substituting a progestogen-only method. It also states plainly that patients who stop must be given alternative contraception advice and that pregnancy must be excluded on admission.

This matters more in medical tourism than in domestic surgery, because the clotting risk of oestrogen-containing contraception compounds with the clotting risk of a long-haul flight taken shortly after an operation. If you are on the combined pill and you are booking surgery abroad, raise it at the first consultation, four weeks out, not the week before you fly.

Red flags: when the medication conversation has gone wrong

No one asked for a medication list. A clinic that books your surgery date before anyone has recorded what you take is not running a pre-operative assessment.

You were told to stop a prescribed drug by a coordinator rather than a doctor. Stop instructions for anticoagulants, antiplatelets and diabetes medication are prescriber decisions.

You were given a generic "stop everything two weeks before" instruction with no drug names in it. That instruction is dangerous for anyone on an antiplatelet after a stent, or on medication for a seizure disorder, thyroid condition or transplant.

Your GP or specialist was never contacted and no one offered to. For patients on anticoagulation, coordination between the prescriber and the operating team is standard practice, not an optional extra.

You were told GLP-1 drugs must be stopped for a week or more with no reference to current guidance. That advice predates the October 2024 multi-society consensus.

How to run the medication conversation properly

Write the list before the consultation: every prescription with its dose and frequency, every over-the-counter drug including painkillers, every vitamin and herbal supplement, and anything you take occasionally. Photograph the packets if that is easier than transcribing them.

Ask for stop instructions in writing, drug by drug, with the number of days for each, and ask who to contact if a stop instruction conflicts with what your own doctor has told you. Then take that written instruction to your GP or prescriber and have them confirm it before you act on it. Where a stop is not clinically safe, the surgical plan should change, not the medication.

Estetica Istanbul coordinates this before travel: the medication list goes to the board-certified partner surgeon and the anaesthetic team at the JCI-accredited partner hospital, and stop instructions come back from clinicians, not from a booking desk.

Frequently asked questions

How long before surgery should I stop taking ibuprofen?

UT Southwestern's guidance groups ibuprofen with the blood thinners it asks patients to pause one to two weeks before surgery. Paracetamol or acetaminophen is usually the substitute offered, because it does not affect platelet function — but confirm the substitution with your surgical team rather than assuming it.

Can I keep taking my blood pressure medication?

Usually yes, and most are continued through the morning of surgery, but some classes are handled differently by anaesthetic teams. This is a question for the anaesthetist at your pre-operative assessment, and it is one they expect to be asked.

What happens if I forget to stop something?

Tell them, before the operation rather than after it. Depending on the drug and the interval, the team may proceed, delay by a few days, or change the anaesthetic plan. An operation postponed by 48 hours is a scheduling problem; an undeclared anticoagulant is a bleeding problem.

Do I need to stop supplements if my surgery is only under local anaesthetic?

The bleeding risk from platelet-affecting supplements applies regardless of anaesthetic type, so the usual advice still stands for anything involving incisions. The interaction risk with anaesthetic agents is what varies. Ask specifically, rather than assuming a smaller procedure means no rules.

If you are considering surgery in Istanbul and you take regular medication, send your medication list to Estetica Istanbul at the enquiry stage rather than at the booking stage. It is the single cheapest way to avoid a cancelled operation, and it occasionally changes the recommendation to a different procedure or a different timeline.
