- USES
-
- Vitamin K is required by the body to produce the blood clots that are
- necessary for wound healing and the day-to-day repair of body tissues.
- Normally, bacteria present in the gastrointestinal tract produce large
- quantities of the vitamin, which is then absorbed into the bloodstream. Some
- vitamin K is also absorbed directly from the foods we eat (leafy green
- vegetables, meats, and dairy products). This medication is used as a
- supplement for those patients who cannot, for various reasons (for example,
- gastrointestinal bypass surgery, malnutrition, antibiotic therapy), absorb
- sufficient vitamin K from their gastrointestinal tracts. This supplement,
- therefore, prevents the blood clotting disorders that would result from
- vitamin K deficiency.
-
- TREATMENT
-
- Vitamin K can be taken either on an empty stomach or, to avoid stomach
- irritation, with food or milk (unless your doctor directs you to do
- otherwise).
- If you miss a dose of this medication, take the missed dose as soon as
- possible, unless it is almost time for the next dose. In that case, do not
- take the missed dose of the medication at all; just return to your regular
- dosing schedule. Do not double the next dose of medication. Be sure to tell
- your doctor about any missed doses.
-
- SIDE EFFECTS
-
- Minor.
-
- Alterations in taste, headache, nausea, stomach upset, or vomiting.
- These side effects should disappear as your body adjusts to the medication.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- itching, shortness of breath, or skin rash.
-
- INTERACTIONS
-
- Vitamin K interacts with a number of other types of medications:
- 1. Antibiotics, quinine, quinidine, aspirin, oral antidiabetic
- medications, cholestyramine, colestipol, and mineral oil can increase the
- dosage requirements of vitamin K.
- 2. Vitamin K can reduce the effectiveness of oral anticoagulants (blood
- thinners, such as warfarin).
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any of those listed above.
-
