What does a high PT INR mean?
PT/INR too high- If a PT/INR test result is too high, it means that the persons’ blood is clotting too slowly, and is at risk of bleeding; their dose of warfarin is too high. On the other hand, if the PT/INR test result is too low, their dose of warfarin may not be enough to protect the blood from clotting.
What is a critical PT INR level?
[8]For patients who are on anticoagulant therapy, the therapeutic INR ranges between 2.0 to 3.0. INR levels above 4.9 are considered critical values and increase the risk of bleeding.
What does it mean if PT time is high?
A typical PT result is 10 to 14 seconds. Higher than that means your blood is taking longer than normal to clot and may be a sign of many conditions, including: Bleeding or clotting disorder.
How do I lower my PT INR?
Asymptomatic patients with an INR that is only slightly above the therapeutic maximum can often be managed simply by omitting their usual warfarin dose and increasing their frequency of INR monitoring. The INR will reduce over several days. Warfarin should be restarted, if necessary, when the INR falls below 5.0.
What causes high INR?
A high INR level can happen when you take warfarin (Coumadin). Warfarin helps prevent blood clots. To do this, it slows the amount of time it takes for your blood to clot. This raises your INR level.
What causes increased PT and INR?
A blood clot in a vein or artery. An acute condition such as disseminated intravascular coagulation (DIC) that may cause both bleeding and clotting as coagulation factors are used up at a rapid rate. A chronic condition such as severe liver disease that may affect hemostasis.
Why is my INR suddenly high?
What foods cause INR to increase?

- Cranberry.

Does warfarin affect the brain?
According to Bunch, it’s possible that patients with erratic warfarin levels are more prone to “small clots” or “small bleeds” that could affect the brain. The findings are based on records from over 10,000 patients who were on warfarin for atrial fibrillation or to prevent blood clots from other causes.
What medications can cause elevated INR?
Colestipol. Estrogens. Sucralfate. Dicloxacillin, Naficillin.
What causes elevated PT INR?
Common causes of a prolonged PT include vitamin K deficiency, hormone drugs including hormone replacements and oral contraceptives, disseminated intravascular coagulation (a serious clotting problem that requires immediate intervention), liver disease, and the use of the anticoagulant drug warfarin.
What are the dangers of high INR levels?
When your INR level shoots above 5, you are at increased risk for hemorrhage. Higher INR’s can even have spontaneous hemorrhage meaning you start bleeding for no reason or no injury. For a person with a high INR, their blood takes a long time to clot or won’t clot, so they become a danger for bleeding out and dying.
What can cause an increased INR?
What increases my risk for an elevated INR? Too much anticoagulant medicine, a type of blood thinner that helps prevent clots Other medicines, such as aspirin, NSAIDs, and some antibiotics, when you also are using anticoagulants Health conditions, such as liver failure or bleeding disorders A sudden decrease of vitamin K in your diet
