How Does Dabigatran Work?

Dabigatran acts by inhibiting thrombin, a protein in the blood that is essential for clot formation. By blocking thrombin’s action, dabigatran helps prevent blood clots from forming, thereby promoting smoother blood flow and reducing the risk of stroke and other clot-related complications.

How to Take Dabigatran

Dabigatran is available in two forms: oral capsules and oral pellets, each with its own set of instructions for proper use. It is essential to follow these instructions to ensure the medication’s effectiveness and minimize potential side effects.

Oral Capsules

• With or Without Food: You can take dabigatran capsules with or without food. However, if you experience an upset stomach, taking the capsule with food may help alleviate this issue.
