Throughout this leaflet SYNTHAMIN 9, 5.5% Amino Acid Intravenous Infusion without electrolytes will be called SYNTHAMIN.
SYNTHAMIN is a sterile solution which contains:
SYNTHAMIN is used to give you food (nutrition) straight into your blood when you cannot take enough food by your mouth.
Your doctor will check your body has all the nutrition that it needs for good health. If necessary, you may also have vitamins (such as folic acid), minerals, fatty acids (the building blocks of fats), electrolytes (salts) and sugar solutions (such as glucose) at the same time as SYNTHAMIN.
You will not be given SYNTHAMIN if any of the above apply to you.
Talk to your doctor or nurse before SYNTHAMIN is given to you.
SYNTHAMIN will only be used if the solution is clear, free from particles and the container is not damaged.
You will have regular blood and urine tests while being given SYNTHAMIN. This will make sure that you are getting the right amount of solution and if necessary, you will be given other treatments. More checks are made if SYNTHAMIN is being given to a very young child.
If any abnormal signs or symptoms of an allergic reaction develop, such as fever, chills, skin rashes or difficulty in breathing, excessive sweating, nausea, or headache, tell the doctor or the nurse: the infusion will be stopped immediately.
SYNTHAMIN can cause the formation of small particles in your blood. If you start to have difficulty breathing or feel short of breath, tell the doctor or the nurse: the infusion will be stopped immediately, and you may need other treatment.
Certain medications and illnesses can increase the risk of developing infection or sepsis (bacteria in the blood). There is a particular risk of infection or sepsis when a tube (intravenous catheter) is placed in your vein. Your doctor will carefully watch you for any signs of infection. Using aseptic “germ free” techniques when placing and maintaining the catheter and when making the nutritional formula can reduce the risk of infection.
If you are severely malnourished such that you need to receive feeding through a vein, it is recommended that parenteral nutrition is started slowly and carefully.
SYNTHAMIN may cause a stinging pain and redness at the place where it goes into your vein if given into your arm.
Your doctor will monitor your condition at the onset of the infusion, particularly if you currently have liver, kidney, heart, or circulation problems.
Amino acid solutions can increase the level of ammonia or nitrogen-containing compounds in your blood. Your doctor will check your blood tests for this. Your doctor should also be aware of severe conditions affecting how your body handles fluid, sugars, fats, proteins, or salt (metabolic disorders). These conditions will be corrected before you are given SYNTHAMIN.
When used in neonates and children below 2 years, the solution (in bags and administration sets) should be protected from light exposure until administration is completed.
Exposure of SYNTHAMIN to ambient light, especially after admixtures with trace elements and/or vitamins, generates peroxides and other degradation products that can be reduced by protection from light exposure.
There are no known problems when SYNTHAMIN is used with other medicines.
Tell your doctor or nurse if you are taking, have recently taken or might take any other medicines.
If you are pregnant, think you might be pregnant or are breast-feeding, tell your doctor. They will decide if you can be given SYNTHAMIN.
Your doctor will decide how much SYNTHAMIN you should be given. It will depend on:
When used in neonates and children below 2 years, the solution (in bags and administration sets) should be protected from light exposure until administration is completed (see section 2). You will not be given SYNTHAMIN through the same tubes and equipment used for any blood transfusion.
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. Giving a volume of SYNTHAMIN that is too large may cause nausea, vomiting, chills, and electrolyte disturbances, in such situations the infusion should be stopped immediately.
In some severe cases, your doctor may have to give you temporary renal dialysis to help your kidneys eliminate the excess product.
To prevent these events occurring, your doctor will regularly monitor your condition and test your blood parameters.
Like all medicines, SYNTHAMIN can cause side effects, although not everybody gets them.
If you notice any changes in the way you feel during or after the treatment, tell your doctor or nurse right away.
The tests your doctor will perform while you are taking the medicine are meant to minimise side effects.
If any abnormal signs or symptoms of an allergic reaction develop, such as abnormally low or high blood pressure, appearance of a blue or purple coloration of the skin, abnormally high heart rate, breathing difficulties, vomiting, nausea, skin rashes, raised body temperature, excessive sweating chills, and shivering, the infusion will be stopped immediately.
Other side effects have been noticed, occurring more or less frequently:
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 (see details below). By reporting side effects you can help provide more information on the safety of this medicine.
