Safely Buy Heparin Vials ( Heparin Sodium, Porcine ) from Canada Prescriptions Plus.


Heparin vials are containers that hold heparin, a medication used as an anticoagulant, that is, it prevents blood from clotting.

Heparin is commonly used in medical settings, such as hospitals, clinics, and pharmacies, for various purposes, including preventing blood clots during surgery, treating and preventing deep vein thrombosis (DVT) and pulmonary embolism, and maintaining the patency of intravenous catheters.

Heparin vials come in different strengths and sizes, typically containing a specific amount of heparin per milliliter (IU/ml) or per vial (IU).
