Vitamin K is used to treat and prevent low levels of certain substances (blood clotting factors) that your body naturally produces. These substances help your blood to thicken and stop bleeding normally (such as after an accidental cut or injury). Low levels of blood clotting factors increase the risk for unusual bleeding. Low levels may be caused by certain medications (such as warfarin) or medical conditions (such as obstructive jaundice). Vitamin K helps to treat and prevent unusual bleeding by increasing the body's production of blood clotting factors.
How to use
If you are taking the over-the-counter product to self-treat, read all directions on the product package before taking this medication. If you have any questions, consult your pharmacist. If your doctor has prescribed this medication, take it as directed.
If you are using the rapidly-dissolving tablets, place under your tongue to dissolve, then swallow with or without water. Some brands may also be swallowed whole.
The dosage is based on your age, medical condition and response to treatment. Do not increase your dose or use this drug more often or for longer than directed. Your condition will not improve any faster, and your risk of side effects will increase.
If you are using a certain "blood thinner" drug (warfarin), vitamin K can decrease the effects of warfarin for up to 2 weeks. Be sure to take your vitamin K and warfarin exactly as directed by your doctor or pharmacist.
If you develop easy bruising or bleeding, or if you think you may have a serious medical problem, get medical help right away. You may need another dose of vitamin K.
