What is Kenadion Tab used for?

Kenadion Tab is primarily used to prevent and treat vitamin K deficiency and associated bleeding disorders. It helps control bleeding in various situations, such as after injuries or in individuals with conditions like hemophilia. It also addresses hypoprothrombinemia, a blood clotting problem that can be caused by long-term use of anticoagulants, antibiotics, or salicylates. Additionally, it can reverse the effects of certain blood thinners like warfarin and is sometimes used to prevent hemorrhagic disease in newborns.

How does Kenadion Tab work?

Kenadion Tab contains Phytomenadione, which is Vitamin K1. This active ingredient works by supplying the body with Vitamin K, a crucial nutrient necessary for the liver to produce essential blood clotting factors (specifically factors II, VII, IX, and X, as well as proteins C and S). By ensuring the proper production of these factors, Kenadion Tab helps the blood clot normally and can also contribute to bone health.

What is the usual dosage for Kenadion Tab?

The dosage of Kenadion Tab should always be as prescribed by your doctor. It can be taken with or without food. For conditions like hypoprothrombinemia, a single maximum oral dose of 25 mg once daily has been mentioned, but specific dosages will vary based on the individual's condition and the doctor's assessment.

What are the possible side effects of Kenadion Tab?

While generally well-tolerated, some possible side effects of Kenadion Tab include dizziness, flushing (a sensation of warmth in the face, ears, neck, and chest), changes in taste, increased sweating, stomach discomfort, and rarely, diarrhea. Less common but more serious side effects can include allergic reactions (such as hives, itching, swelling, or difficulty breathing), unusual bleeding or bruising, low blood pressure, rapid or weak pulse, muscle stiffness, yellowing of the eyes or skin, decreased appetite, chest pain, and skin rash. If any side effects persist or worsen, consult your doctor.

Is Kenadion Tab safe during pregnancy or breastfeeding?

Pregnancy: Kenadion Tab is classified as a Category C pregnancy drug. This means that animal studies have shown potential harm to the fetus, but there are no adequate and well-controlled studies in humans. It should only be used during pregnancy if the potential benefits justify the potential risks, and only under the strict guidance of a doctor.

Breastfeeding: Caution is advised when using Kenadion Tab while breastfeeding, and it is recommended to consult your doctor. While Vitamin K does pass into breast milk, it is generally considered unlikely to harm the infant.

Can Kenadion Tab be taken with other medications?

Yes, Kenadion Tab can interact with other medications. It's crucial to inform your doctor about all prescription and non-prescription drugs, as well as any vitamins, supplements, or herbal products you are currently taking. Kenadion Tab can reduce the effectiveness of blood thinners (anticoagulants) like warfarin or heparin. High doses of aspirin may also increase the risk of bleeding when taken with Kenadion Tab. Additionally, certain medications like bile acid sequestrants can impair its absorption, and some antibiotics may also affect its action.

What precautions should be taken while using Kenadion Tab?

Before taking Kenadion Tab, inform your doctor if you have any known allergies to Phytomenadione or any other ingredients. Exercise caution and inform your doctor if you have a history of liver disease, kidney disease, heart disease, cholestatic disease, G6PD deficiency, or certain blood disorders. It should be avoided if you have existing blood clots (thrombosis) or certain hypercoagulable states. Alcohol consumption should be avoided as it may increase dizziness and drowsiness. Also, inform your doctor if you are scheduled for any surgery or dental procedures.

What happens if a dose of Kenadion Tab is missed?

If you miss a dose of Kenadion Tab, take it as soon as you remember. However, if it is almost time for your next scheduled dose, it is best to skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for the missed one, as this could increase the risk of side effects.

How should Kenadion Tab be stored?

Kenadion Tab should be stored in a cool and dry place, away from direct sunlight, moisture, and heat. The recommended storage temperature is typically between 20-25°C or below 30°C. It should not be frozen and must be kept out of the sight and reach of children.
