Vitamin K1 (phylloquinone) is a prescription nutrient (vitamin K1) prescribed to people whose blood is not clotting because of a vitamin K deficiency or an inability of the body to use K vitamins. All the K vitamins are a critical part of the blood's ability to form the proteins that are used to form blood clots, so a problem with vitamin K leads to bleeding diseases.
Vitamin K1 is often prescribed to patients on other drug regimens, such as aspirin (salicylate), antibacterial drugs, and others, that interfere with the body's ability to use vitamin K to form blood clotting proteins. Therapy using these drugs often requires treatment with phytonadione, as well, to prevent bleeding problems.
Medical conditions can often cause a vitamin K deficiency. These include liver problems (bile obstruction), chronic diarrhea, celiac disease, Crohn's disease, and swelling and sores in the colon (ulcerative colitis). Vitamin K1 is also sometimes advised or prescribed to women who are pregnant or nursing.
Vitamin K1 along with other K vitamins is typically given as an injection to newborns to prevent vitamin K deficiency bleeding, a rare but potentially fatal condition in newborns.
Vitamin K1 is a fat-soluble vitamin, so people with problems absorbing fats, such as children with cystic fibrosis, will often be prescribed water-soluble Vitamin K1 to prevent bleeding problems along with the other fat-soluble vitamins (the so-called ADEK vitamins).
Vitamin K1 is taken as a tablet or injection.
While not a complete list, the most common side effects of Vitamin K1 are changes in taste, flushing, sweating, dizziness, fast heartbeat, or blue lips, skin, or nails. Allergic reactions are rare and usually due to the inactive ingredients in a Vitamin K1 supplement or injection.
