Medically reviewed by Last updated on Jul 24, 2023.

Applies to dabigatran: oral capsule, oral packet.


Oral route (Capsule; Pellet)

Premature Discontinuation Increases The Risk Of Thrombotic EventsPremature discontinuation of any oral anticoagulant, including dabigatran etexilate, increases the risk of thrombotic events. If anticoagulation with dabigatran etexilate is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant.Spinal/Epidural HematomaEpidural or spinal hematomas may occur in patients treated with dabigatran etexilate 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 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 administration of dabigatran etexilate and neuraxial procedures is not known. Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary. Consider the risks and benefits before neuraxial intervention in patients anticoagulated or to be anticoagulated.
