This medicine helps prevent blood clots by stopping a substance in your body that forms them.
Adults typically take 220 mg once daily for clot prevention after surgery, or 300 mg twice daily for stroke prevention and treating existing clots; doses vary based on age, kidney function, and other medications. Children 8 years and older take doses based on weight and age, twice daily.
Swallow the capsule whole with a glass of water, with or without food. Do not break, chew, or open the capsule, as this increases the risk of bleeding.
The maximum daily dose for adults is 600 mg (taken as 300 mg twice a day). For some conditions, it can be 220 mg once daily. For children, the maximum daily dose is determined by their weight and age, up to 600 mg.
Suitable for older adults, with specific precautions. Consider renal impairment, age and body weight when determining the dosage. Consider potential interactions especially with other drugs that increase the risk of bleeding. (updated 19.9.2025)
