kilogram of your bodyweight in a day.
SYNTHAMIN should be stored as follows: Do not store above
25ºC and protect it from light.

Children under two years old should not use SYNTHAMIN.
You will not be given SYNTHAMIN through the same tubes and
equipment used for any blood transfusion.

Do not use SYNTHAMIN after the expiry date which is stated
on the label after Exp. The expiry date means the last day of

If you are given too much
Your doctor will give you SYNTHAMIN so it is unlikely that you
will be given too much. If you are worried that you have had
too much, tell your doctor or nurse.
If the dose given is too high or the infusion too fast, the amino
acid content may make your blood too acid and you may have
too much fluid in the circulation.

SYNTHAMIN is for single use only. Partly used bags should not
be used again. Any left over solution should be thrown away
safely by a healthcare professional. All equipment will be
thrown away safely by a healthcare professional after use.
