What is Dabigatran for?
Dabigatran belongs to a class of medications called Direct or Novel Oral Anticoagulant. It is used to treat blood clots, including that in deep vein and in major blood vessel in the lung, and to prevent potential stroke in atrial fibrillation patients (but not for those with abnormal heart valve).
How to use it?
Dabigatran can be taken orally.
For preventing stroke in atrial fibrillation and treating DVT or PE, the usual dose is 150 mg twice daily.
For preventing DVT or PE after hip replacement, the initial dose is 110 mg 1-4 hours after surgery. After the patient has stopped bleeding on the first day, the dose is 220 mg once daily for 28-35 days.
A lower dose is used in patients with poorer kidney function.
What are the side effects of Dabigatran?
The most common side effect is higher chance of bleeding, for example easier bruising, black tarry stools (gastrointestinal bleeding) , pink urine (bleeding in the urinary tract), which may lead to anemia.
Who should not take Dabigatran?
– Anyone who is sensitive to Dabigatran or any ingredients in the medicine
– Anyone actively bleeding
– Anyone with severe kidney impairment
As Dabigatran increases the chance of bleeding, be careful and avoid injury. Use a soft toothbrush and an electric razor. Make sure you take every dose, as you may risk a potentially fatal blood clot. If you have signs of abnormal bleeding, please find your doctor right away.
Common dosing schedule:
Dabigatran can be taken with or without food. Swallow the whole capsule. Do not chew, break, crush or dissolve. Take it at the same time on a daily basis. Unlike conventional anticoagulants (e.g. warfarin), Dabigatran has less dietary restrictions.
What if I miss a dose?
Dabigatran is usually taken twice daily. If you remember it within 6 hours, take the missed dose immediately; if is is over 6 hours, skip the missed dose and go back to your normal dosing schedule. Do not take two doses at the same time. Please record the date of the missed dose and tell the doctor in the next follow-up.
This schedule is for reference only, adjustments may be made according to individual needs.
Some common medications Dabigatran may interact with:
– Antiplatelet agents (e.g. aspirin, clopidogrel)
