Vitamin K Inj Uses and How to Use

  • Uses

    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 (e.g., 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 (e.g., warfarin) or medical conditions (e.g., obstructive jaundice). Vitamin K helps to treat and prevent unusual bleeding by increasing the body's production of blood clotting factors.

    How To Use

    This medication is given by injection under the skin or into a muscle or vein by a health care professional. If this medication is given into a vein, it should be injected very slowly (no more than 1 milligram per minute) to reduce the risk of serious side effects. (See also Warning section.)

    Dosage is based on your medical condition and response to treatment.

    If you are using a certain "blood thinner" drug (warfarin), vitamin K can decrease the effects of warfarin for up to 2 weeks. Therefore, be sure to take your vitamin K and warfarin exactly as directed by your doctor or pharmacist.

    If you develop easy bruising or bleeding, seek immediate medical attention. You may need another dose of vitamin K.
