  1. Remove the child-proof cap from the bottle by pushing down on the cap while turning it anticlockwise.
  2. Take the plastic circular adaptor from the carton and push this into the neck of the bottle. This should fit tightly and once it is in place it should not be removed.

  5. Turn the bottle upside down. Keep hold of the bottle in one hand and the syringe in the other.
  6. Hold the barrel of the syringe steady and slowly, pull the plunger down until you see the medicine fill the barrel to the mark which matches the number of ml that you need to give to your child.
  7. Turn the bottle the correct way up. Keeping hold of the barrel, remove the whole syringe from the adaptor.
  8. Put the syringe tip into your baby’s mouth. Drip the medicine in by pushing down the plunger gently while still holding the barrel. Don’t hurry your child, allow time for him or her to swallow the medicine slowly. Alternatively, empty the measured dose from the syringe onto a spoon for your child to take the medicine from.
  9. Replace the cap on the bottle of medicine.
  10. Wash the syringe in warm soapy water and rinse well. Hold the syringe under water and move the plunger up and down several times to make sure the inside of the barrel is clean. Store the syringe in a hygienic place with the medicine.
