WARNING

Dabigatran is an anticoagulant medication used to prevent blood clots and reduce the risk of stroke in people with atrial fibrillation and for the treatment and prevention of blood clots in veins. While it’s effective for many patients, there are risks associated with its use:

• Bleeding: One of the primary risks of taking Dabigatran is bleeding. Since it reduces the blood’s ability to clot, it can increase the risk of bleeding events, including minor bleeding like nosebleeds to more serious ones like gastrointestinal bleeding or intracranial hemorrhage.
• Interaction with other medications: Dabigatran can interact with other medications, including over-the-counter drugs and supplements. This interaction may affect the blood’s clotting ability and increase the risk of bleeding or reduce the effectiveness of either medication.
• Kidney function: Dabigatran is primarily eliminated from the body through the kidneys. Impaired kidney function can lead to higher levels of Dabigatran in the body, increasing the risk of bleeding. Dosage adjustments are necessary for patients with reduced kidney function.
• Spinal or epidural procedures: Patients taking Dabigatran are at risk of spinal or epidural hematomas if they undergo spinal procedures or receive epidural anesthesia. This can lead to long-term or permanent paralysis.
• Allergic reactions: Some individuals may experience allergic reactions to Dabigatran, although this is rare. Symptoms may include rash, itching, swelling, severe dizziness, or trouble breathing.
• Liver function: Although less common, Dabigatran can affect liver function tests in some patients, leading to potential liver problems.
• Increased risk of heart attack: In some cases, Dabigatran has been associated with an increased risk of heart attack, particularly in patients with coronary artery disease or a history of heart attacks.

It’s crucial for patients taking Dabigatran to be aware of these risks and to regularly monitor their health, report any unusual symptoms to their healthcare provider, and follow their prescribed dosage regimen closely.

Why is this medication prescribed?

Dabigatran is prescribed for several medical conditions primarily related to blood clotting:

• Atrial Fibrillation: It’s commonly prescribed for patients with atrial fibrillation (an irregular heartbeat) to reduce the risk of stroke and systemic embolism. Atrial fibrillation can cause blood to pool in the heart, increasing the risk of clot formation, which can lead to strokes if the clots travel to the brain.
• Treatment and Prevention of Venous Thromboembolism: Dabigatran is also used to treat and prevent venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE). These conditions occur when blood clots form in the veins, usually in the legs (DVT), and can potentially travel to the lungs (PE), causing serious complications.
• Prevention of Clots after Hip or Knee Replacement Surgery: It’s prescribed for preventing blood clots in patients who have undergone hip or knee replacement surgery. These procedures carry a high risk of blood clots forming in the legs due to immobility after surgery, which can lead to serious complications if the clots travel to the lungs.

Dabigatran belongs to a class of medications called direct oral anticoagulants (DOACs), or novel oral anticoagulants (NOACs). Unlike traditional anticoagulants like warfarin, which require regular monitoring of blood clotting levels (INR), DOACs like Dabigatran offer the advantage of fixed dosing without routine monitoring. However, they also carry risks such as bleeding, and dosages may need adjustment based on kidney function and other factors.

How should this medicine be used?

Dabigatran should be used exactly as prescribed by a healthcare professional. Here are some general guidelines for its use:

• Dosage: Follow the prescribed dosage regimen carefully. Dabigatran is usually taken by mouth with or without food as directed by your doctor. Dosage may vary depending on the medical condition being treated, kidney function, and other factors. Do not change your dose unless instructed by your doctor.
• Timing: Take Dabigatran at the same time each day to maintain a consistent level of the medication in your body.
• Swallow Whole: Swallow the capsules whole with a full glass of water. Do not break, chew, or crush the capsules.
• Do Not Stop Abruptly: Do not stop taking Dabigatran suddenly without consulting your doctor, as this can increase the risk of blood clots and stroke. If you need to stop the medication for any reason, your doctor will provide instructions on how to do so safely.
• Missed Dose: If you miss a dose of Dabigatran, take it as soon as you remember on the same day. If it is almost time for your next dose, skip the missed dose and resume your regular dosing schedule. Do not double dose to catch up.
• Storage: Store Dabigatran capsules at room temperature away from light and moisture. Keep them out of reach of children.
• Regular Monitoring: While Dabigatran does not require routine blood monitoring like warfarin, your doctor may periodically check your kidney function and other blood tests to ensure the medication is working effectively and safely.
• Medical Alert: Inform healthcare providers (including dentists and surgeons) about your Dabigatran use before undergoing any medical procedures or surgeries, as it may need to be temporarily stopped to reduce the risk of bleeding.

Always follow your doctor’s instructions and ask any questions you may have about your medication regimen.

Other uses for this medicine

• Secondary Prevention of VTE: Dabigatran may be used for extended treatment following the initial treatment of venous thromboembolism (VTE) to prevent recurrence.
• Prevention of Stroke in Patients with Mechanical Heart Valves: Some studies have investigated the use of Dabigatran for preventing stroke in patients with mechanical heart valves, although this is not yet an approved indication in many countries.
• Other Cardiovascular Conditions: There is ongoing research into the potential use of Dabigatran in other cardiovascular conditions, such as heart failure and coronary artery disease, although its role in these conditions is not yet well-established.

What special precautions should I follow?

Special precautions to follow when taking Dabigatran include:

• Bleeding Risk: Dabigatran increases the risk of bleeding, so it’s important to take precautions to avoid injury and to promptly report any signs of bleeding to your healthcare provider.
• Kidney Function: Since Dabigatran is primarily eliminated by the kidneys, it’s important to monitor kidney function regularly, especially in patients with impaired kidney function. Dosage adjustments may be necessary in these patients.
• Liver Function: While Dabigatran is not metabolized by the liver to a significant extent, it’s still important to monitor liver function tests periodically, as liver dysfunction can affect the metabolism and clearance of the medication.
• Drug Interactions: Dabigatran can interact with other medications, including both prescription and over-the-counter drugs, as well as supplements. Inform your healthcare provider about all medications and supplements you are taking to avoid potentially harmful interactions.
• Spinal or Epidural Procedures: Patients taking Dabigatran are at risk of spinal or epidural hematomas if they undergo spinal procedures or receive epidural anesthesia. These procedures should be avoided or managed carefully under the guidance of a healthcare professional.
• Pregnancy and Breastfeeding: Dabigatran is not recommended during pregnancy, as it may harm the unborn baby. It’s also not recommended during breastfeeding, as it may pass into breast milk.

Always consult with your healthcare provider for specific guidance and recommendations based on your individual medical history and circumstances.

What special dietary instructions should I follow?

Regarding special dietary instructions, there are no specific dietary restrictions for Dabigatran. However, maintaining a balanced diet and avoiding excessive alcohol consumption is generally recommended for overall health. Additionally, be cautious with foods that may affect blood clotting, such as those high in vitamin K (e.g., leafy green vegetables), although the impact of dietary vitamin K on Dabigatran’s effectiveness is minimal compared to warfarin.

What should I do if I forget a dose?

If you forget to take a dose of Dabigatran, take it as soon as you remember on the same day. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for a missed one. If you have any concerns or questions about missed doses, consult your healthcare provider for guidance.

What side effects can this medication cause?

Dabigatran, like any medication, can cause side effects, although not everyone experiences them. Common side effects of Dabigatran include:

• Bleeding: This is the most significant side effect of Dabigatran. It can manifest as nosebleeds, bleeding gums, prolonged bleeding from cuts, blood in urine or stool, and heavy menstrual bleeding. Serious bleeding events, such as gastrointestinal bleeding or intracranial hemorrhage, can also occur, although they are less common.
• Indigestion or Heartburn: Some people may experience indigestion, stomach pain, or heartburn while taking Dabigatran.
