Dear customer, Following the recent Canadian shortage of Heparin Sodium Injection 5 000 units / 0.5 mL in vials (www.drugshortagescanada.ca), Sterinova would like to bring clarification regarding the source of heparin used in our prefilled syringes. Sterinova does not use crude heparin from China. Our crude heparin is sourced from Europe, North and South America. In
