Xarelto in Your System: How Long Does It Stay? Find Out Here!
Category: Drug Information
Blood thinners are a life-saving medication that, according to the National Blood Clot Alliance, over eight million Americans are currently taking. Xarelto is a popular choice, as is the generic version, Rivaroxaban.
Xarelto is a powerful anticoagulant that not only treats but prevents blood clots from forming. This is an important medication for people with atrial fibrillation, deep vein thrombosis, and more.
Doctors recommend taking Xarelto at the same time each day. How long does Xarelto stay in your system? What happens if you miss a dose?
Read on as we share everything you need to know about Xarelto metabolism, side effects, and more.
How Does Xarelto Work?
First, let’s take a quick look at how Xarelto reduces the threat of blood clots. Its key ingredient, Rivaroxaban, is a Factor Xa inhibitor. When you take Xarelto, it will:
- Bind to the enzyme Factor Xa, an important trigger for coagulation
- Reduce the production of thrombin and fibrin, coagulation starters produced by Factor Xa
- Decrease platelet aggregation
- Prolong clotting time by inhibiting prothrombinase activity
Xarelto is one of the fastest-acting blood thinners, reaching maximum concentration in the bloodstream (and therefore taking full effect) within two to four hours. How effective it is depends on how much of it is in the bloodstream, which is why many doctors start patients on a higher dosage for the first one to two weeks.
How and When Should You Take Xarelto?
Your doctor should give you explicit instructions on how and when to take Xarelto. Always make sure that you’re following these instructions, as Xarelto dosages tend to reflect the condition it’s treating. For example, patients will often:
- Take 20 mg once a day for atrial fibrillation
- Take 10 mg once a day to prevent DVT
- Take 2.5 mg twice a day for CAD
Your doctor will also specify whether or not you should take Xarelto with food. No matter what you’re taking Xarelto for, you should always aim to take it at the same time each day. This ensures that you’re maintaining even levels of the drug in your bloodstream.
How Long Does Xarelto Stay in Your System?
Maybe you have an active lifestyle and worry that you might miss a dose, or you have surgery coming up and need to eliminate Xarelto from your system before your surgery begins. How long does Xarelto stay in your system? Let’s take a closer look at what the manufacturer has to say.
Onset of Effectiveness
As we mentioned earlier, Xarelto is going to take effect between two and four hours after you take it. This is a faster onset than other blood thinners such as Warfarin, which can take several days to take effect. Likewise, Xarelto also leaves the system faster than other blood thinners.
Xarelto Medication Elimination
For most adults, Xarelto will completely clear from the system after 24-45 hours of taking the last dose. Between five and nine hours after taking Xarelto, 50% of it will have left the body. Only two-thirds of Xarelto is metabolized by the liver, with the other third getting eliminated, unchanged, through the kidneys.
Factors That Impact Duration
Why is the window of Xarelto elimination (24-45 hours) so wide? A variety of factors can impact blood thinner duration, including kidney function and age. In fact, elderly patients using Xarelto may have an elimination timeline of up to 65 hours.
Xarelto Side Effects
Some patients who are prescribed Xarelto for long-term use notice manageable side effects. These may include:
- Fatigue
- Abdominal pain
- Itching
- Back pain
- Dizziness
- Minor bleeding (e.g., more frequent nose bleeds)
All blood thinners can pose a risk of more serious bleeding when taken for long periods of time. Make sure to keep up with any follow-up appointments your doctor recommends to monitor for potential side effects and determine if Xarelto is still the right prescription for you.
Risks Associated with Skipping Doses of Xarelto
According to a study published with the National Library of Medicine, there are potential risks of stopping Xarelto without talking to your doctor first. If you discontinue taking Xarelto abruptly, you could face an increased risk of:
- Stroke or systemic embolism
- Myocardial infarction
- Death
More specifically, you may face an increased risk of these serious outcomes when Xarelto completely leaves your system. This can occur within 24-45 hours of taking the last dose.
What to Do If You Miss a Dose
If you miss a dose of Xarelto, consult your doctor or pharmacist about what to do next. In most cases, you should take a single dose of Xarelto as soon as you realize you’ve missed your typical window. Most patients shouldn’t double up on doses, even if they’ve missed two, but this will depend on how often you take Xarelto and what you take it for.
How to Make Xarelto More Affordable
Unfortunately, many Americans are uninsured or underinsured, which can make prescription drugs difficult to afford. There are solutions available to you to access many prescriptions at a reduced cost. Let’s take a quick look at your options.
Talk to Your Doctor About Rivaroxaban
Rivaroxaban is the generic alternative to Xarelto. Because it did not require the same patents and research to create, you can buy Rivaroxaban at a lower price than Xarelto. However, you should always talk to your doctor about switching to generic medications, as some patients will need to take the name-brand version due to factors like allergies or drug antagonism.
