What Is Phytonadione?
Phytonadione (Vitamin K) is a prescription medication used to manage Vitamin K deficiency and associated coagulopathy. It works by restoring adequate levels of Vitamin K, which is essential for the hepatic synthesis of clotting factors II, VII, IX, and X. With the right dose and ongoing monitoring, most patients see normalization of clotting function and a reduction in abnormal bleeding.

Is Online Phytonadione Treatment Right for You?
Doctronic can evaluate adults who have been diagnosed with or are showing signs of Vitamin K deficiency, including those experiencing unexplained bruising, prolonged bleeding, or elevated INR. Phytonadione may also be appropriate for patients whose Vitamin K levels have been depleted by poor nutrition, malabsorption disorders, or long-term antibiotic use.
Because Vitamin K plays a central role in the coagulation system, a careful review of your blood clotting history and any medications that affect coagulation is required before treatment begins. Our licensed physicians assess your complete health picture to ensure Phytonadione is safe and appropriate for you.

Frequently asked questions
Phytonadione is a synthetic form of Vitamin K1. It works by providing the liver with the Vitamin K it needs to produce clotting factors II, VII, IX, and X. Without adequate Vitamin K, these clotting factors cannot be activated, which leads to a higher risk of bleeding. Phytonadione restores this process.
Phytonadione is used to treat Vitamin K deficiency, which can cause excessive bleeding or bruising, elevated INR, and prolonged prothrombin time. It is also used to reverse the effects of certain anticoagulant medications that work by blocking Vitamin K, such as warfarin, under physician supervision.
Phytonadione is available in oral tablet form and injectable form. For outpatient management of deficiency, oral dosing is most common. Your physician will determine the appropriate dose and duration based on your lab results, symptoms, and underlying cause of deficiency.
Oral Phytonadione typically begins to improve clotting factor levels within 6 to 12 hours, with more significant effects seen within 24 hours. Laboratory values such as INR and prothrombin time are usually re-checked after treatment to confirm response.
Yes. Phytonadione can counteract the anticoagulant effects of warfarin (Coumadin). Patients on warfarin who are prescribed Phytonadione require careful INR monitoring. Certain antibiotics, mineral oil, and bile acid sequestrants can also affect Vitamin K absorption. Always inform your physician of all medications you are taking.
Oral Phytonadione is generally well tolerated. Some patients may experience mild gastrointestinal upset, including nausea. Rare hypersensitivity reactions have been reported, particularly with injectable forms. Contact your physician if you experience any unusual symptoms after starting treatment.
