Falls and blood thinners: why a fall is more serious, and what families should do

A fall or a head strike is more serious for a parent on a blood thinner, because bleeding, including bleeding on the brain, is harder to stop. Yet for most people the stroke the medicine prevents is more dangerous than the fall, so never stop it on your own. Prevent falls at home, and treat any blow to the head as an emergency.

Important: This is general education, not medical advice. Do not start, stop, or change any medication based on this article. Talk with your parent's doctor or pharmacist about their situation, and call 911 in an emergency.

If your parent is on a blood thinner and stumbles now and then, the fear is real and reasonable. Falls are the leading cause of injury-related death for adults 65 and older, and about 1 in 4 older adults falls each year (CDC). This guide starts where families worry most, why a fall matters more on a blood thinner and what to do when one happens, then walks through the bleeding signs to watch, how to make the home safer, and the reassuring truth about why the medicine is usually worth keeping.

Why is a fall more dangerous on a blood thinner?

A blood thinner slows the body's clotting, which is exactly what protects against a stroke. The trade off is that when bleeding does start, it is harder to stop. After a fall, a bruise can be larger, a cut can bleed longer, and bleeding inside the body, where you cannot see it, can keep going.

The most serious concern is a blow to the head. A knock that a person not on a blood thinner might shrug off can cause bleeding between the skull and the brain, and on a blood thinner that bleeding can build slowly over hours before any symptom appears. This is why a head strike is treated as an emergency even when your parent feels fine. It is also why fall prevention matters so much: the goal is to keep the fall from happening in the first place, not to give up the medicine that is preventing a stroke.

What should we do if our parent falls or hits their head?

If there was any blow to the head, treat it as an emergency. Call 911 or go to the emergency room right away, even if your parent seems completely fine, and tell the team which blood thinner they take (StatPearls; Mayo Clinic). Bleeding in the brain on a blood thinner can appear hours later, so waiting to see if symptoms show up is not safe.

For a fall with no head strike, you usually do not need the emergency room, but do watch closely. Apply steady, firm pressure to any cut that is bleeding. Then call the doctor the same day if you notice a bad or worsening headache, large or spreading bruising, swelling, pain that does not settle, or bleeding you cannot control. Keep a card or phone note with your parent's blood thinner name and dose so any clinician, in any parish, knows immediately how to treat a bleed or a head injury.

What bleeding warning signs should we watch for?

Watch for bleeding that will not stop and for signs of bleeding inside the body. Some easy bruising is common. Call the doctor for things that are new or getting worse, and call 911 for a hard fall or head strike, a sudden severe headache, new confusion or weakness, or heavy bleeding you cannot control (StatPearls; Mayo Clinic).

Call the doctor, the same day, if you notice:

1. Nosebleeds or bleeding gums that keep coming back
2. Easy bruising, or bruises larger than usual
3. Pink, red, or brown urine
4. Black, tarry, or bloody stools
5. Unusually heavy menstrual bleeding
6. A small cut that takes a long time to stop bleeding

Call 911 or go to the emergency room right away if:

1. Your parent falls and hits their head, even if they seem fine afterward
2. There is a sudden severe headache, or new confusion, slurred speech, or weakness on one side
3. They vomit something that looks like coffee grounds, or cough up blood
4. Bleeding will not stop with steady, firm pressure
5. They faint, or have a racing heartbeat with cold, clammy, pale skin

When in doubt about a head injury, do not wait to see if symptoms appear. Bleeding in the brain on a blood thinner can show up hours later, so it is safer to be checked.

How can we prevent falls at home?

The strongest way to protect a parent on a blood thinner is to keep them from falling at all. Most falls happen at home, and most can be prevented with a few practical changes plus a check-in with the doctor (CDC STEADI; NIA). Think of it as a home safety sweep paired with a health review.

Make the home safer, room by room:

1. Clear the paths. Remove or tape down loose rugs, and keep floors, stairs, and hallways free of cords, clutter, and anything easy to trip on.
2. Add light. Bright, even lighting matters most on stairs and in hallways, and night lights along the route from the bed to the bathroom prevent falls in the dark (NIA).
3. Put in grab bars. Install grab bars beside the toilet and inside the tub or shower, and add a non-slip mat in the bath. A raised toilet seat and a shower chair help too (NIA).
4. Steady the stairs. Make sure there are secure handrails on both sides, and mark the top and bottom step so they are easy to see.
5. Fix the footwear. Sturdy, well-fitting, non-slip shoes indoors and out are safer than socks, slippers, or bare feet.

Review the health side with the doctor:

1. Ask for a fall-risk check. The CDC's STEADI program gives doctors a simple way to screen fall risk, review balance, and make a plan (CDC STEADI).
2. Review the medicines. Some drugs cause dizziness, drowsiness, or low blood pressure that raises fall risk, so ask the doctor or pharmacist to look over the whole list (NIA).
3. Check vision and hearing. Out-of-date glasses and poor hearing both make falls more likely, so keep exams current.
4. Build strength and balance. Physical therapy, or programs that improve leg strength and balance, are among the most effective ways to reduce falls (NIA).
5. Ask about an evaluation. If your parent has already fallen, feels unsteady, or is afraid of falling, ask the doctor for a fall-risk evaluation, and consider having a physical or occupational therapist assess the home.

My parent falls sometimes: should they stop the blood thinner?

It is the right question, and the honest answer is reassuring. For most people, the stroke a blood thinner prevents is more dangerous than the bleeding a fall might cause. A 2025 University of Bath study found that stopping the medicine often does more harm than the fall risk it was meant to avoid (ScienceDaily, 2025).

Large reviews have found no clear increase in major bleeding from falls alone in atrial fibrillation patients taking anticoagulants, and cardiologists note that fear of falling is the single most common reason blood thinners are wrongly withheld (Cleveland Clinic Journal of Medicine). The American Geriatrics Society does flag these medicines for extra caution in adults 65 and older, and they can add to dizziness or low blood pressure that raises fall risk (2023 Beers Criteria, via AAFP). That is a reason for careful dosing, fall prevention, and regular review, not for stopping the medicine on your own.

Why is my parent on a blood thinner?

Doctors prescribe blood thinners to prevent strokes and dangerous clots. The most common reason in older adults is atrial fibrillation, an irregular heartbeat that lets clots form and can raise stroke risk about five times when untreated (Mayo Clinic). Others treat a clot in the leg or lung, or protect a heart valve.

The medicines are also called anticoagulants. They do not literally thin the blood; they slow the body's clotting so a clot is less likely to form and travel to the brain, heart, or lungs. Blood thinner use is common and growing in this age group: adults 65 and older make up most of the people taking one, and use across US adults rose from roughly 1.6 percent to 2.3 percent between the periods 2009 to 2012 and 2017 to 2020 (JACC/NHANES analysis). If your parent has been prescribed one, they are in very good company.

Warfarin or a DOAC: what is the difference?

Blood thinners come in two families. Warfarin (Coumadin, Jantoven) has been used for decades and needs regular INR blood tests plus care with food and other medicines. Newer pills called DOACs (Eliquis, Xarelto, Pradaxa, Savaysa) usually need no routine blood tests and are now first choice for most people with atrial fibrillation (Mayo Clinic; GoodRx).

Neither is simply better for everyone. DOACs have become the majority of blood thinner prescriptions, rising to roughly 59 percent of anticoagulant use by 2017 to 2020 (JACC/NHANES analysis), but warfarin is still the right choice for some people, such as those with a mechanical heart valve or certain kidney concerns. Which one fits your parent is a decision for their doctor, not something to switch on your own.

What should we ask the doctor?

Bring a written list to the next visit. Good questions cover which blood thinner and why, whether it needs INR blood tests, what to avoid, and the plan for a fall, a bleed, or a procedure. Asking these up front turns anxiety into a clear plan, and it never means changing the dose yourself.

1. Why is this the right blood thinner for my parent, warfarin or a DOAC?
2. Does it need regular INR blood tests, and who arranges and tracks them?
3. Which foods, supplements, or over-the-counter medicines should we avoid?
4. Which over-the-counter pain reliever is safe? Many families are surprised that aspirin and ibuprofen can add to bleeding risk.
5. What should we do right away if my parent falls or hits their head?
6. What exact bleeding signs mean call you, versus call 911?
7. Is there a reversal treatment for an emergency, and does our local hospital carry it?
8. What is the plan around dental work, a colonoscopy, or surgery?
9. Could a fall-risk check or physical therapy help lower the chance of a fall?

A practical note for Louisiana families

Keep a current medication list, with the blood thinner's name and dose, somewhere easy to grab. During hurricane season an evacuation can send a family to an emergency room in another parish where no one knows your parent's history. A simple card in a wallet or on a phone tells any clinician, anywhere in the state, that your parent takes a blood thinner, which changes how a bleed or a head injury is treated.

How an advisor can help

A blood thinner, and the worry about falls that comes with it, is one thread in the larger picture of a parent's health and daily safety. If you are weighing whether they need more help at home, a fall-safer living space, or a community with staff nearby, a Louisiana advisor can talk it through with you. The practice works for your family at no cost to you, and never sells your information or shops you around. One advisor, from the first call to the decision. A move is only one possible outcome: more support at home, or simply a clear plan, may be the right answer. If it helps, the MyCare Recommendation your advisor prepares can lay out the options in plain language.

This article is general education, not medical advice. Figures are population estimates and vary from person to person. Do not start, stop, or change any medication based on it: your parent's doctor or pharmacist is the only person who should adjust their treatment, and in an emergency, call 911.

Common questions from families

Is a fall on a blood thinner an emergency?

A fall with any blow to the head is an emergency: call 911 or go to the emergency room right away, because bleeding on the brain can appear hours later. A fall without a head strike is not automatically an emergency, but call the doctor the same day if you see heavy bruising, swelling, or bleeding that will not stop.

What should I do if my parent on a blood thinner falls?

Check whether their head was hit, and if it was, call 911 even if they seem fine. For a fall with no head strike, watch closely for a bad headache, large or spreading bruises, swelling, or bleeding that will not stop, and call the doctor the same day. Have their blood thinner name ready for the care team.

How do I prevent falls if my parent is on a blood thinner?

Make the home safer: clear loose rugs and clutter, brighten lighting and add night lights, install grab bars by the toilet and in the shower, and keep them in sturdy non-slip shoes. Ask the doctor for a fall-risk check, a medication review, and a vision exam, and consider physical therapy to build strength and balance (CDC STEADI; NIA).

Can my parent stop their blood thinner because they keep falling?

Not on your own. For most people the stroke a blood thinner prevents is more dangerous than a fall, and a 2025 University of Bath study found that stopping often causes more harm than the fall risk it was meant to avoid. Talk with the doctor before any change.

What should I do if my parent on a blood thinner hits their head?

Treat it as an emergency and call 911 or go to the emergency room, even if they seem fine. A head strike on a blood thinner can cause bleeding in the brain that shows up hours later. Tell the team which blood thinner they take.

Is bruising on a blood thinner something to worry about?

Some easy bruising is common and usually not an emergency. Call the doctor the same day if bruises are large, spreading, or appear without a bump, or if you also see bleeding gums, nosebleeds that will not stop, or blood in the urine or stool.

Do DOACs need blood tests like warfarin?

Usually not. Warfarin needs regular INR blood tests to keep the dose right, while newer DOACs like Eliquis and Xarelto generally need no routine monitoring, which is one reason they are now first choice for most people with atrial fibrillation.

Why do doctors keep older adults on blood thinners despite the fall risk?

Because for most people the protection against stroke outweighs the bleeding risk from falls. Studies find no clear rise in major bleeding from falls alone, and fear of falling is the top reason blood thinners are under-prescribed.
