blood thinners · anticoagulants · clot prevention pills · living on blood thinners · anticoagulant medicines

These medicines stop the blood from clotting too easily and protect against blood clots. But bruises and bleeding come more easily, so it helps to know a few rules.

After a blood clot, with some heart rhythm problems, after a valve replacement, and in other conditions, as decided by your doctor.

⏱ Duration: usually months or lifelong; some people need regular blood tests

Be sure to tell your doctor

Tell every doctor and dentist that you take a blood thinner
Before any surgery, tooth removal, or joint injection
If bruises appear for no reason or your gums bleed
If you start a new medicine, herb, or supplement

How to prepare

Timing. Take it at the same time every day. Set a reminder.
Tests. If your doctor ordered a clotting test, have it on schedule.
Food. With some medicines, steady eating matters, for example green vegetables. Ask your doctor about yours.

Common questions

Can I take a painkiller for a headache?

Not all of them. Some painkillers increase bleeding. Ask your doctor which one is safe for you.

Can I have dental treatment?

Yes. Be sure to tell your dentist about your medicine beforehand. Your doctor decides whether to stop it.
