1. What Omeflex special is and what it is used for
Omeflex special contains fluids and substances called amino acids, electrolytes and fatty acids that are essential for the body to grow or to recover. It also contains calories in the form of carbohydrates and fats. Omeflex special is given to adults, adolescents and children older than two years.
You are given Omeflex special when you are unable to eat food normally. There are many situations when this might be the case, for example when you are recovering from surgery, injuries, or burns, or when you are unable to absorb food from your stomach and gut.

- blocking of blood vessels by blood clots or fat (embolism) • severe liver failure
- impaired bile flow (intrahepatic cholestasis)
- severe kidney failure in the absence of kidney replacement therapy • disturbances of your body salt composition

Warnings and precautions
Talk to your doctor, pharmacist or nurse before using Omeflex special. Please inform your doctor if:
- you have heart, liver or kidney problems
- you suffer from certain types of metabolic disorders such as diabetes, abnormal blood fat values and disorders of your body fluid and salt composition or your acid-base balance
You will be monitored closely to detect early signs of an allergic reaction (such as fever, shivering, rash, or shortness of breath) when you receive this medicine.
Further monitoring and tests such as various examinations of blood samples will be applied to make sure that your body handles the administered foodstuffs properly.
Your healthcare professional will also take measures to ensure that your body’s fluid and electrolyte requirements are met. In addition to Omeflex special you will receive further nutrients (foodstuffs) in order to fully cover your requirements.
Children

Package leaflet: Information for the user
B. Braun Melsungen AG · 34209 Melsungen, Germany
Omeflex® special emulsion for infusion
The following information is intended for healthcare professionals only: Parenteral nutrition products should be visually inspected for damage, discolouration and emulsion instability before use.
Do not use bags which are damaged. Overwrap, primary bag and the peel seams between the chambers should be intact. Only use if the amino acid and glucose solutions are clear and colourless up to straw-coloured and the lipid emulsion is homogenous with milky white appearance. Do not use if the solutions contain particulate matter.
After mixing the three chambers, do not use if the emulsion shows discolouration or signs of phase separation (oil drops, oil layer). Stop the infusion immediately in case of discolouration of the emulsion or signs of phase separation.
Before opening the overwrap, check the colour of the oxygen indicator (see Figure A). Do not use if the oxygen indicator turned pink. Use only if the oxygen indicator is yellow.
Preparation of the mixed emulsion
Strict adherence to aseptic
handling principles must be
complied with.
To open: Tear overwrap starting
from the tear notches (Fig. 1).
Remove the bag from its protective
overwrap. Discard overwrap, oxygen
indicator and oxygen absorber.
Visually inspect the primary bag for leaks. Leaky bags must be discarded, since the sterility cannot be guaranteed.
Mixing of the bag and addition of
additives
To open and mix the chambers
sequentially, roll the bag with both
hands, starting first by opening the
peel seam that separates the top
chamber (glucose) and the bottom
chamber (amino acids) (Fig. 2).
B|BRAUN
✃
Then continue applying pressure so that the peel seam separating the middle chamber (lipids) and the bottom chamber opens (Fig. 3).
3
After all chambers are mixed and following the removal of the aluminium seal (Fig. 3A), one can add compatible additives via the medication port (Fig. 4). Mix the contents thoroughly (Fig. 5) and visually inspect the mixture (Fig. 6). The mixture is a milky white homogenous oil-in-water emulsion. There should be no signs of emulsion phase separation.

Omeflex special can be mixed with the following additives up to the below specified upper concentration limits or maximum amount of additives after supplementation. The resulting admixtures are stable for 7 days between +2 °C to +8 °C plus 2 days at 25 °C.
- Electrolytes: take account of the electrolytes already present in the bag; stability has been demonstrated up to a total quantity of 200 mmol/l of sodium + potassium (sum), 9.6 mmol/l of magnesium and 6.4 mmol/l of calcium in the ternary mixture.
- Phosphate: stability has been demonstrated up to a maximum concentration of 20 mmol/l for inorganic phosphate or up to a maximum concentration of 30 mmol/l for organic phosphate (not both at the same time).
- Alanyl-Glutamin up to 24 g/l.
- Trace elements and vitamins: stability has been demonstrated with commercially available multi-trace elements and multi-vitamins (e.g. Tracutil, Cernevit) up to the standard dosage recommended by the respective manufacturer of the micronutrient.
Detailed information about the above mentioned additives and the corresponding shelf life of such admixtures can be provided on demand by the manufacturer.
Preparation for infusion
The emulsion should always be brought to room temperature prior to infusion.
Remove the aluminium foil from the infusion port (Fig. 7) and attach the infusion set (Fig. 8). Use a non-vented infusion set or close the air vent when using a vented set. Hang the bag on an infusion stand (Fig. 9) and carry out infusion using the standard technique.
For single use only. Container and unused residues must be discarded after use.
Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
Do not reconnect partially used containers.
The medicinal product must be administered via a lipid-permeable filter with a pore size of 1.2 µm.
Shelf life after removing the protective overwrap and after mixing of the contents of the bag
Chemical and physicochemical in-use stability of the mixture of amino acids, glucose and fat was demonstrated for 7 days at 2-8 °C and additional 2 days at 25 °C.
Shelf life after admixture of compatible additives
From a microbiological point of view, the product should be used immediately after admixture of additives. If not used immediately after admixture of additives, in-use storage times and conditions prior to use are the responsibility of the user. After first opening (spiking of the infusion port)
The emulsion is to be used immediately after opening of the container. Omeflex special must not be mixed with other medicinal products for which compatibility has not been documented.
Omeflex special should not be given simultaneously with blood in the same infusion set due to the risk of pseudoagglutination.
