Drug Class

Direct Oral Anticoagulant (Factor Xa Inhibitor)

Pregnancy

Category B — Animal reproduction studies have not demonstrated fetal harm, but human data are limited. Apixaban use during pregnancy is generally avoided because it crosses the placenta and may increase the risk of obstetric and fetal bleeding. Low molecular weight heparin remains the preferred anticoagulant during pregnancy.

Available Forms

Oral tablet (2.5 mg, 5 mg)

What It's Used For

is prescribed to treat:

• Preventing stroke in atrial fibrillation and treating blood clots • Various related conditions in the cardiovascular category • Associated symptoms and complications

It is an important medication that helps manage these conditions effectively.

Side Effects

Common side effects may include:

• Nausea or stomach upset • Headache • Dizziness or lightheadedness • Fatigue or tiredness • Mild rash or itching

Serious side effects (seek immediate medical attention):

• Severe allergic reactions (rash, hives, swelling, difficulty breathing) • Unusual bleeding or bruising • Severe stomach pain • Signs of liver problems (yellowing of skin/eyes, dark urine) • Chest pain or irregular heartbeat • Severe dizziness or fainting • Signs of serious adverse effects

Drug Interactions

Apixaban is a substrate of CYP3A4 and P-glycoprotein, so concurrent strong inhibitors or inducers of these pathways materially affect plasma levels and bleeding risk.

Strong dual CYP3A4 and P-gp inhibitors (e.g., ketoconazole, itraconazole, ritonavir, clarithromycin): Increase apixaban exposure roughly twofold and raise major bleeding risk. Avoid co-administration; if unavoidable at the 5 mg or 10 mg dose, reduce by 50%. Avoid altogether at the 2.5 mg dose.
Strong dual CYP3A4 and P-gp inducers (e.g., rifampin, carbamazepine, phenytoin, St. John's wort): Decrease apixaban exposure and may reduce efficacy, increasing thromboembolic risk. Avoid concurrent use.
Other anticoagulants and antiplatelets (e.g., warfarin, heparin, aspirin, clopidogrel, ticagrelor): Additive bleeding risk. Combine only when clearly indicated, such as during a transition between agents or in select acute coronary syndrome regimens, with close monitoring.
NSAIDs (e.g., ibuprofen, naproxen, ketorolac): Increase gastrointestinal bleeding risk. Use the lowest effective NSAID dose for the shortest duration; favor topical NSAIDs or acetaminophen when possible.
SSRIs and SNRIs (e.g., sertraline, fluoxetine, venlafaxine): Mildly increase bleeding risk through impaired platelet serotonin uptake. No dose adjustment required, but counsel patients on bleeding signs.

Frequently Asked Questions

No. Unlike warfarin, apixaban does not require routine INR monitoring because it has a predictable anticoagulant effect at fixed doses. However, your provider will periodically check kidney function, liver function, and a complete blood count — typically at least annually, and more often if your clinical status changes.

Take the missed dose as soon as you remember on the same day, then resume your normal twice-daily schedule. If you do not remember until it is nearly time for the next dose, skip the missed dose and take only the next scheduled one. Never double up — doing so increases bleeding risk without improving stroke or clot protection.

Yes. Andexanet alfa (Andexxa) is an FDA-approved reversal agent for life-threatening bleeding caused by apixaban or rivaroxaban. Four-factor prothrombin complex concentrate (4F-PCC) is also used in many hospitals. If you have major trauma or uncontrolled bleeding, go to the nearest emergency department immediately.

Light to moderate alcohol use (up to one drink per day for women, two for men) is generally considered acceptable, but heavier drinking increases the risk of falls, gastrointestinal bleeding, and liver injury — all of which can amplify apixaban-related bleeding. Discuss your drinking habits honestly with your physician.

Stop apixaban 24 to 48 hours before surgery depending on bleeding risk and your kidney function. Most routine dental cleanings and simple extractions can proceed without stopping the drug, often with local hemostatic measures. Always coordinate timing with both your prescriber and the proceduralist.

Questions to Ask Your Doctor

Consider discussing these topics at your next appointment:

✓Am I a candidate for the reduced 2.5 mg twice daily dose based on my age, weight, and kidney function?
✓Which over-the-counter pain relievers are safe for me to use while on apixaban?
✓How should I manage my apixaban around upcoming procedures, surgery, or dental work?
✓What signs of bleeding should prompt me to call you or go to the emergency department?
✓How long will I need to stay on apixaban for my specific condition?
