(A) Premature Discontinuation Of Eliquis Increases The Risk Of Thrombotic Events

Premature discontinuation of any oral anticoagulant, including ELIQUIS, increases the risk of thrombotic events. If anticoagulation with ELIQUIS is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS, and Clinical Studies].

(B) Spinal/Epidural Hematoma

Epidural or spinal hematomas may occur in patients treated with ELIQUIS who are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include:

  • use of indwelling epidural catheters
  • concomitant use of other drugs that affect hemostasis, such as nonsteroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, other anticoagulants
  • a history of traumatic or repeated epidural or spinal punctures
  • a history of spinal deformity or spinal surgery
  • optimal timing between the administration of ELIQUIS and neuraxial procedures is not known [see WARNINGS AND PRECAUTIONS]

Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary [see WARNINGS AND PRECAUTIONS].

Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated [see WARNINGS AND PRECAUTIONS].


ELIQUIS (apixaban), a factor Xa (FXa) inhibitor, is chemically described as 1-(4 -methoxyphenyl)-7-oxo-6-[4-(2-oxopiperidin-1-yl)phenyl]-4,5,6,7-tetrahydro-1H-pyrazolo[3,4c]pyridine-3-carboxamide. Its molecular formula is C25H25N5O4, which corresponds to a molecular weight of 459.5. Apixaban has the following structural formula:

ELIQUIS® (apixaban) Structural Formula Illustration

Apixaban is a white to pale-yellow powder. At physiological pH (1.2–6.8), apixaban does not ionize; its aqueous solubility across the physiological pH range is ~0.04 mg/mL.

ELIQUIS tablets are available for oral administration in strengths of 2.5 mg and 5 mg of apixaban with the following inactive ingredients: anhydrous lactose, microcrystalline cellulose, croscarmellose sodium, sodium lauryl sulfate, and magnesium stearate. The film coating contains lactose monohydrate, hypromellose, titanium dioxide, triacetin, and yellow iron oxide (2.5 mg tablets) or red iron oxide (5 mg tablets).

What are the possible side effects of apixaban (Eliquis)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have:

  • easy bruising, unusual bleeding (nose, mouth, vagina, or rectum), bleeding from wounds or needle injections, any bleeding that will not stop;
  • heavy menstrual periods;
  • headache, dizziness, weakness, feeling like you might pass out;
  • red, pink, or brown urine;
  • black or bloody stools, coughing up blood or vomit that looks like coffee...
