A tooth extraction, a cataract, a small skin procedure — and the advice arrives: stop the blood thinner for a week. After a stent, that week is not a small thing.
The instinct to stop is understandable; bleeding is visible and immediate, while a stent thrombosis is neither until it happens. But the two risks are not equal, and they are not yours or the dentist's to weigh alone.
Why the medicines are there in the first place
A stent is a metal scaffold sitting inside an artery. Until the body lines it with its own cells, platelets will stick to it given the chance. Antiplatelet medicines — aspirin plus one of clopidogrel, ticagrelor or prasugrel — are what prevent that. Stopping both of them early is one of the commonest triggers for a stent clotting shut, and that presents as a heart attack rather than as a warning.
Most procedures do not require you to stop anything
Routine dental scaling, a simple filling, most single-tooth extractions, cataract surgery under local anaesthesia and most skin procedures can be done while you continue your medicines, using local measures to control bleeding. The sensible default is to continue unless there is a specific reason not to.
The decision depends on dates as much as on the procedure
- How long ago the stent was placed.
- How complex the stented segment was, and how many stents were used.
- How much bleeding the planned procedure genuinely risks, and whether bleeding there can be seen and controlled.
- Whether you have had a bleeding problem before.
These pull in opposite directions, which is why two people having the same extraction can correctly be given different advice.
Do not make the change yourself, or on a dentist's note alone
Take the planned procedure, its date, and your current medicine list to the cardiologist who knows your stent. If a pause really is needed, it gets planned properly: which drug, for how many days, and when to restart — usually within 24 to 48 hours of the procedure.
Two different drug families, two different sets of rules
Antiplatelets — aspirin, clopidogrel, ticagrelor, prasugrel — and anticoagulants — warfarin, dabigatran, rivaroxaban, apixaban — are not interchangeable, and some patients take one from each group. Carry your discharge summary, or a photograph of your current prescription, to every appointment: dental, eye, surgical and emergency.
When to seek help urgently
- Chest pain or heavy discomfort after stopping any heart medicine.
- Bleeding from a wound or gum that will not settle with firm local pressure.
- Black or tarry stools, or blood in vomit or urine.
- Sudden breathlessness, sweating or collapse.
