When should I stop?

A medicine by medicine answer

Which medicines to stop before surgery, and when

Type the names on your boxes, brand or active ingredient, in any spelling, and see for each one whether to keep taking it, skip it on the day, or stop it days before. Every line carries its source, so your own doctor can check it. If a product is not in the list, you can send me a photo of the box on WhatsApp.

It reads the box, not a category

Eliquis or apixaban, Solgar or Doppelherz, spelled the Turkish, German, Arabic or Russian way: the list knows more than 20,000 brand names from the European, Turkish, Swiss and British medicine registries, and the ingredients of thousands of supplement labels.

Your list stays in your browser

Nothing you type is saved, with one exception: a name the list does not know is recorded on its own, with nothing about you, so that I can add it.

It follows the consensus, and says so

Each answer comes from a published perioperative consensus statement or guideline. Where none exists, the card says plainly that the rule is my own clinic policy. It does not replace the doctor who prescribes your medicine.

Check your medicines

Choose the kind of procedure, then type your medicines, one per line.

When should I stop?

Type the medicines and supplements you take, exactly as the box says, and see what to do with each one before your procedure. The answers come from published perioperative consensus statements; the source is shown next to every line.

1. What are you having done?

2. Your medicines

One per line or separated by commas. Brand name or active ingredient, either works. Spelling does not have to be perfect.

This check reflects published consensus statements and my own practice; it does not replace the instructions of the doctor who prescribes your medicine. Blood thinners, insulin, steroids, and psychiatric, epilepsy, transplant and cancer medicines are always confirmed with the prescribing doctor before any change. Bring every box to your consultation. Nothing you type is stored, with one exception: a name the list does not recognise is saved on its own, without anything about you, so that I can add it.

Where the guidance comes from

The rules come from the consensus statements of the Society for Perioperative Assessment and Quality Improvement on supplements, pain medicines, cardiovascular, endocrine, neurologic, psychiatric, gastrointestinal, pulmonary, rheumatologic and HIV medicines, the 2025 statement on GLP-1 receptor agonists, the CHEST 2022 and ESC 2022 guidelines and the PAUSE study for blood thinners, and the 2026 ISTH bleed risk classification, which counts the operations I perform as high bleeding risk. Every result lists the sources it used.

If you have not decided yet and want the wider picture, medicines, smoking, weight and timing together, the surgery readiness check walks through it. For the days after surgery, the recovery planner builds a plan.
