1. What is Isoplex and what does it do?
Isoplex is a temporary plasma substitute solution containing
succinylated gelatin 4% w/v (Plasma is the fluid component of
blood in which the red cells and white cells are carried).
Isoplex is administered directly into a vein via a drip tube
(intravenous infusion).
You will be given Isoplex if you have lost blood or body fluids
because of bleeding, injury, surgery, burns or infections. It
takes time for your body to replace the blood or body fluids
that you have lost. Isoplex can help maintain the volume
of fluid in your blood vessels during that time. Isoplex is not
intended to provide nutrition nor replace blood components
such as red cells which carry oxygen or white cells which fight
infection; Isoplex can only replace lost fluid volume.
Isoplex can be used for the treatment of initial blood loss
during pregnancy.
2. Before being given Isoplex
Do not allow Isoplex to be given to you if you know that you
are allergic (hypersensitive) to succinylated gelatin.
If you are suffering or have suffered from the following
conditions, please tell your doctor or nurse before being
given Isoplex;
• Heart failure
• Kidney (renal) failure
• Liver disease
Please inform your doctor or nurse if you are taking, or have
recently taken, any other medicine, including those
medicines obtained without a prescription.
Please ask your doctor or nurse for advice if you are pregnant
or breastfeeding.
3. How much Isoplex to use and for how long?
You will be given Isoplex via a drip tube inserted into a vein.
It is unlikely that you will ever have to use Isoplex yourself;
infusion fluids are mainly intended to be given by your doctor
or nurse.
Your doctor or nurse will work out how often you should have
Isoplex, and how much Isoplex should be used. The amount
given will depend upon your individual needs. You might also
be given other infusion fluids or products made from blood, or
a blood transfusion.
For infusion the usual dose rates are:
For Adults:
500 – 1500 ml/hour
For Children:
150 – 1500 ml/hour
For Elderly:
As Adults

Each container of Isoplex is designed to last only a few
hours at a time; most of the succinylated gelatin is passed
out of the body in less than 12 hours. For this reason, you
may be given more Isoplex when your doctor or nurse
thinks this is necessary. In time, your body will make up
the blood or body fluids that you have lost.
4. Possible Side Effects
Like all medicines Isoplex can cause side effects, although
not everybody gets them.
Rarely, (between 1 in 1,000 and 1 in 10,000 people), patients
may experience an allergic like reaction. Tell your doctor
or nurse immediately if you notice any of the following:
• Swelling of your face, mouth or throat
• Changes in your breathing, e.g. fast breathing, difficulty
breathing out, wheezing
• Changes in the way your heart beats, e.g. fast beating
• Changes in your blood pressure, e.g. feeling dizzy or
faint, headache
• Changes in your body temperature, e.g. chills, fever,
• Abnormal feelings in your skin, including itching, rash,
swelling or any other changes to your skin
• Shaking of your arms and/or legs
Reporting of side effects
If you get any side effects, talk to your doctor, nurse or
pharmacist. This includes any possible side effects not listed
in this leaflet. You can also report side effects directly via the

• the container shows any sign of leakage
