If your doctor just put you on Xarelto, you’ve probably already typed “Xarelto side effects” into Google more than once. That’s completely normal. Blood thinners aren’t like your average prescription. They change how your blood clots, which means even small side effects deserve your attention.
The good news? Most people who take Xarelto do fine. But knowing what’s normal, what’s worth a phone call, and what’s a trip to the ER can make the whole experience a lot less stressful.
What Is Xarelto, Exactly?
Xarelto is the brand name for rivaroxaban, a type of blood thinner known as a Factor Xa inhibitor. Doctors prescribe it to prevent or treat blood clots, think deep vein thrombosis (DVT), pulmonary embolism, or clot-related strokes, especially in people with atrial fibrillation.
Unlike older blood thinners like warfarin, Xarelto doesn’t require constant blood testing or diet restrictions. That convenience is a big reason it’s so widely prescribed. But convenience doesn’t mean risk-free, and understanding rivaroxaban side effects is part of using it safely.
The Most Common Xarelto Side Effects
Since Xarelto’s whole job is to slow down clotting, it makes sense that bleeding-related issues top the list. Here’s what shows up most often:
- Easy bruising, bumps that used to leave nothing now leave a mark
- Nosebleeds that take longer than usual to stop
- Bleeding gums, especially after brushing or flossing
- Heavier or longer menstrual periods
- Minor cuts that bleed longer than expected
- Upset stomach, nausea, or mild stomach pain
- Back pain (usually mild, but worth mentioning to your doctor)
- Itching or minor skin reactions
These aren’t usually dangerous, but they’re your body’s way of telling you the medication is working, and that you need to be a little more careful day to day. Using a soft-bristle toothbrush, an electric razor instead of a blade, and being extra cautious with sharp objects can go a long way.
Blood Thinner Risks You Shouldn’t Ignore
This is the part that matters most. All blood thinner risks come down to one core issue: bleeding that’s more serious than a bruise or a nosebleed. Call your doctor or seek emergency care if you notice any of the following:
Signs of serious internal bleeding
- Blood in your urine (pink, red, or brown color)
- Black, tarry, or bloody stools
- Coughing up blood or vomit that looks like coffee grounds
- Unusual or severe headache, dizziness, or weakness
- Bleeding that won’t stop after 10 minutes of direct pressure
Signs of a spinal or epidural blood clot If you’ve had a spinal tap, epidural, or spinal surgery while on Xarelto, watch closely for back pain, numbness, tingling, muscle weakness in your legs, or loss of bladder or bowel control. This is a rare but serious complication that needs immediate medical attention, since delayed treatment can lead to lasting nerve damage.
Signs of a severe allergic reaction Swelling of the face, lips, tongue, or throat; trouble breathing; or a widespread rash and hives means you should get emergency help right away.
Signs of a stroke or heart problem Sudden confusion, slurred speech, chest pain, a racing or irregular heartbeat, or sudden vision changes are all reasons to call 911.
None of this is meant to scare you. It’s meant to help you recognize the difference between “this is uncomfortable” and “this needs a doctor right now.”
Why You Should Never Stop Xarelto on Your Own
Here’s something people don’t always expect: stopping Xarelto suddenly can be just as risky as the bleeding side effects. If you skip doses or quit the medication without talking to your doctor first, your risk of a blood clot, stroke, or heart attack can actually go up.
If side effects are bothering you, the right move is always to call your doctor and talk through the options, not to make the decision solo.
Who’s More Likely to Have Problems?
Certain things can raise your chances of bleeding complications on Xarelto, including:
- Being over age 65
- Having kidney or liver problems
- Taking other medications that thin the blood, like aspirin or NSAIDs (ibuprofen, naproxen)
- Having a history of stomach ulcers or GI bleeding
- Drinking alcohol regularly
If any of these apply to you, it doesn’t mean you can’t take Xarelto. It just means your doctor will likely want to monitor you a bit more closely.
Simple Ways to Stay Safe on Xarelto
A few small habits can make a real difference:
- Take it exactly as prescribed, same time each day, with or without food depending on your dose.
- Tell every provider you see that you’re on a blood thinner, including your dentist.
- Wear a medical alert bracelet if you can, especially if you’re at higher risk for bleeding.
- Avoid contact sports or activities with a high risk of injury.
- Watch for interactions, always check with your pharmacist before starting a new medication or supplement.
- Keep follow-up appointments, even if you’re feeling fine.

Frequently Asked Questions
Is bruising easily a normal Xarelto side effect?
Yes. Since Xarelto slows down clotting, minor bruising and slightly longer bleeding from small cuts are common and usually not a cause for alarm. If bruises appear without any known bump, or seem unusually large, mention it at your next appointment.
How do I know if my bleeding is an emergency?
Any bleeding that won’t stop after firm pressure for 10 minutes, blood in your urine or stool, coughing or vomiting blood, or a sudden severe headache all count as emergencies. When in doubt, call your doctor or go to urgent care.
Can I take ibuprofen or aspirin with Xarelto?
Generally, this combination raises your bleeding risk and should be avoided unless your doctor specifically tells you it’s okay. Acetaminophen (Tylenol) is usually a safer choice for pain relief, but always confirm with your provider first.
What happens if I miss a dose of Xarelto?
This depends on your specific dosing schedule, so it’s best to follow the instructions given by your doctor or pharmacist. In general, take it as soon as you remember on the same day, but never double it to make up for a missed dose without medical guidance.
Are Xarelto’s side effects different from other blood thinners?
Every anticoagulant carries bleeding risk, but Xarelto doesn’t require the frequent blood testing that older drugs like warfarin do. That said, the underlying risks, including bruising, bleeding, and rare but serious complications, are similar across the blood thinner category.
Can I drink alcohol while taking Xarelto?
Occasional, moderate alcohol use is generally considered lower risk, but heavy or frequent drinking can increase bleeding risk and should be discussed with your doctor.
The Bottom Line
If anything about your symptoms feels off, don’t wait it out. A quick call to your doctor is always the safer choice.
