How Warfarin Z Works

Warfarin works by inhibiting vitamin K–dependent clotting factors (II, VII, IX, and X) in the liver. This reduces clot formation and helps prevent the progression or recurrence of thrombotic events.

Dosage and Administration of Warfarin Z

Typically taken once daily at a fixed time
Requires regular INR or prothrombin time testing

Important Instructions:

Warfarin has significant interactions with:

Antibiotics (e.g., azithromycin, erythromycin, tetracycline)
NSAIDs and aspirin (increased bleeding risk)
Antidepressants (e.g., fluoxetine, paroxetine, sertraline)
Gastrointestinal drugs (e.g., cimetidine, omeprazole, ranitidine)
