Vitamin K Injection (Phytomenadione)
Vitamin K Injection contains phytomenadione, a fat-soluble vitamin essential for blood clotting and preventing excessive bleeding. It is commonly used to treat or prevent bleeding disorders caused by vitamin K deficiency or certain medical conditions. Administered intramuscularly (IM) or intravenously (IV), it ensures rapid correction of clotting factor deficiencies.
Key Benefits
- Prevents and Treats Bleeding: Effective for bleeding disorders such as vitamin K deficiency or excessive anticoagulant use.
- Corrects Clotting Factor Deficiency: Supports the production of clotting factors (II, VII, IX, X) in the liver.
- Newborn Prophylaxis: Prevents Vitamin K Deficiency Bleeding (VKDB) in newborns.
- Fast-Acting: Quickly restores normal clotting in emergency situations.
Common Uses
- Newborn Prophylaxis: Administered to newborns shortly after birth to prevent bleeding complications.
- Overdose of Anticoagulants: Reverses excessive bleeding caused by anticoagulant therapy (e.g., warfarin).
- Liver Disease: Treats bleeding disorders associated with impaired liver function.
- Vitamin K Deficiency: Addresses deficiencies caused by poor diet, malabsorption, or prolonged antibiotic use.
How to Use
- Administration:
- Administered via intramuscular (IM) or intravenous (IV) injection by a healthcare provider.
- Newborns are typically given a single IM dose shortly after birth.
- Dosage:
- Adults: 10-20mg, depending on the severity of the deficiency or bleeding.
- Children: 1-5mg, adjusted based on weight and condition.
- Newborns: 0.5-1mg IM as a single dose.
- Monitoring: Blood clotting time and prothrombin time (PT) are monitored to evaluate response.
Who Can Use It?
Vitamin K Injection is suitable for newborns, children, and adults experiencing or at risk of vitamin K deficiency or bleeding disorders.
Precautions
- Possible Side Effects:
- Common: Pain or swelling at the injection site.
- Rare: Severe allergic reactions, including anaphylaxis, especially with IV administration. Seek immediate medical attention if these occur.
- Not for Routine Use in Adults: Use only under medical supervision and for specific indications.
- Avoid Overdose: Excess vitamin K can cause complications such as hemolysis or jaundice in infants.
