Neokay
⚠ This medicine appears to have been discontinued
The electronic medicines compendium (emc) no longer publishes a Summary of Product Characteristics for this product, which usually means it is no longer marketed in the UK. The patient leaflet below is kept for reference, but the product may not be available.
If you were prescribed this medicine, other products containing Phytomenadione may still be available. Do not stop your treatment — ask your pharmacist or GP what to use instead.
What it is and what it is used for
FOR Neokay contains phytomenadione, a synthetic Vitamin K, which is essential in the body for blood to clot. Newborn babies can have too little Vitamin K and so may develop a serious, but rare condition that causes bleeding. Neokay is used to prevent your baby from developing a tendency to bleed due to a deficiency in vitamin K. 2. BEFORE YOU USE NEOKAY Do not use Neokay:
- if your baby is showing any signs of an allergic reaction to Neokay or any of its ingredients (listed in section 6).
- if your baby is not well enough to be fed within a few hours of birth
- if the baby's mother is taking carbamazepine, phenobarbital, phenytoin, rifampicin or warfarin. Take special care with Neokay:
- if your baby has protein C or protein S deficiency and/or is currently taking warfarin. Do not give Neokay to your baby unless specifically advised to do so by their consultant.
- If your baby has a bleed (eg from the cord stump) or shows signs of bruising consult your doctor immediately.
How to take it
NEOKAY Always use Neokay exactly as your doctor has told you. You should check with your doctor or helalthcare professional if you are not sure. Healthy newborn babies, including healthy premature babies: The contents of a single Neokay capsule should be given. Cut the narrow tip off the capsule and squeezing the liquid into the baby's mouth, as shown in the picture. Another dose should be given if the first dose is spat out or the baby is sick within three hours of the dose being given.

Breast-fed babies: Breast milk contains relatively little vitamin K. The contents of a single Neokay capsule should be given at birth. This protects healthy babies from the risk of bleeding due to vitamin K deficiency in the first week of life. For babies who are only being breast-fed, the contents of a single capsule should be given once weekly for 12 weeks. This offers the best protection against late vitamin K deficiency bleeding. Each dose should be given as described above.
If you forget to give a dose, give one as soon as you remember and continue to give the remainder of the doses as directed. If you have any further questions on the use of this product, ask your doctor or healthcare professional.

Neokay is indicated for the prevention of vitamin K deficiency bleeding in babies
4.2. Posology and method of administration
Oral prophylaxis in healthy neonates, including healthy preterm babies:
The contents of a single Neokay capsule should be administered by cutting the narrow tubular tip off the capsule and squeezing the liquid into the baby's mouth. Another dose should be given if the first dose is spat out or the baby is sick within three hours of the dose being given.
Unwell babies and babies of mothers taking carbemazepine, phenobarbital, phenytoin, rifampicin or warfarin at the time of delivery:
Babies who are not well enough to be fed within a few hours of birth and babies whose mothers are taking any of the above drugs should be treated with an intramuscular formulation of vitamin K at birth.
