How to take this drug

For adults, the usual dose is 5 to 10 mg taken once daily by mouth. Your doctor will decide the exact dose based on your condition. You can take it with or without food, but taking it with a small meal that contains some oil or fat helps your body absorb it better.

What if I Miss a Dose?

If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not take two doses at once to make up for it.

What to watch out for

Only buy from licensed pharmacies — avoid buying Vitamin K products from roadside vendors or unregistered shops as you may get fake or expired products. Do not self-diagnose bleeding problems; see a doctor first to confirm you actually need vitamin K before taking it. Products like Manfes Vitamin K Tablets should be used exactly as directed by your pharmacist or doctor — do not increase the dose on your own.

Common Side Effects

Stomach upset or nausea
headache
skin rash or itching
a funny or unusual taste in the mouth

Serious Side Effects

Yellowing of the eyes or skin (jaundice) — go to the hospital immediately. Signs of a serious allergic reaction like difficulty breathing
swelling of the face or throat
or severe skin rash — seek emergency help right away. Dark-coloured urine or unusual tiredness which may be a sign of red blood cell breakdown.

Drug Interactions

Blood thinners like warfarin — Vitamin K3 works against blood thinners and can make them less effective, so tell your doctor if you are on warfarin. Antibiotics taken for a long time can lower your body's own vitamin K, which may change how this drug works. Avoid drinking alcohol heavily while taking this medication as it can worsen liver problems and affect how the drug works.
