How to give Zithromax Suspension in children less than 3 years of age
If your child is under three years of age or weighs up to 15kg in bodyweight, you
should measure the dose as clearly as possible using the 10ml oral dosing syringe
provided. The syringe is graduated in 0.25ml divisions, providing 10mg of azithromycin
(the active ingredient) in every graduation.
A. Instructions for the syringe
Filling the syringe with medicine
1. Shake the bottle before use and remove the child-proof cap.
2. An adaptor for the syringe should have been fitted into the
neck of the bottle of medicine by the pharmacist. If this has not
been done, take off the adaptor from the syringe and fit to the
neck of the bottle as shown. The adaptor is so that you can fill
the syringe with medicine from the bottle.
3. Check the dispensing label attached by your pharmacist to see
how much medicine needs to be taken.
4. While the bottle is sitting on a firm, flat surface, hold it steady
with one hand. With the other hand insert the tip of the syringe
into the adaptor.
5. Turn the bottle upside down while holding the syringe in place.
6. Slowly pull back the plunger of the syringe so that the top edge
is level with the graduation mark corresponding to the quantity
in the millilitres (ml) prescribed by your doctor.
7. If large bubbles can be seen in the syringe, slowly push the
plunger back into the syringe. This will force the medicine back
into the bottle. Repeat step 6 again.
8. Hold the syringe and bottle firmly. Turn the bottle upright, with
the syringe still in place.
9. Remove syringe from bottle.
Giving the medicine using the syringe
1. Make sure your child is supported in an upright position.

syringe towards the inside of your child’s cheek.
