Viant uses, dose and side effects


powder for infusion, solution

What Viant is and what it is used for

Viant is a powder for infusion solution that is given via a drip. It contains 13 vitamins (see section 6). Viant is given directly into your blood to cover your daily need for vitamins. Viant thus maintains normal body functions in situations where you cannot get the vitamins through normal food intake.

Viant can be given to adults and children from 11 years of age.

The vitamins found in Viant may also be approved to treat other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.

  • if you have too much calcium in your blood (hypercalcemia)

  • if you already have diseases and/or disorders that can lead to hypercalcemia and/or hypercalciuria

    • have short bowel syndrome (lack of nutrient absorption as a result of bowel surgery), inflammatory bowel disease (e.g. Crohn’s disease or ulcerative colitis ),
    • using metformin (medicine to treat diabetes ) for more than four months,

  • if you regularly drink alcohol (more than three standard glasses per day or seven standard glasses per week).

Contact a doctor or nurse immediately if you get signs of an allergic reaction such as sweating, skin redness, hives, or difficulty breathing. Infusion one will then be stopped immediately and appropriate treatment given.

Additional monitoring and tests such as various blood tests and liver function tests may be performed to check that your body is handling the vitamins you are receiving properly.

Healthcare professionals can also take steps to ensure that your vitamin needs are met. In addition to Viant, you can also get other vitamins to completely cover your needs.


This solution must not be given to newborns, infants, or children under 11 years of age.

Other medicines and Viant

Tell your doctor, pharmacist, or nurse if you are taking, have recently taken, or might take any other medicines.

Medicines containing vitamin A or substances similar to vitamin A ( retinoids ) must not be taken during treatment with Viant due to the risk of hypervitaminosis A (see section 3).

Viant can affect or be affected by certain other medicines. Tell your doctor, pharmacist, or nurse if you are using any of the following:

  • medicines for the treatment of acne or psoriasis ( retinoids ), e.g. bexarotene or acitretin
  • medicines for the treatment of epilepsy, eg phenobarbital, phenytoin, carbamazepine, fosphenytoin, and primidone
  • medicines to treat HIV (antiretroviral medicines, tipranavir)
  • antibiotics
  • anti- inflammatory drugs
  • medicines for the treatment of fungal infection, e.g. ketoconazole

Viant and sampling

Viant should not be given to you immediately before a blood glucose or urine test, as it contains vitamin C which can lead to false test results.

Viant contains 0.06 mg of biotin per vial. If you are going to have laboratory tests, you must tell your doctor or the laboratory staff that you are taking or have recently taken Viant, because biotin can affect the results of these tests. Depending on the test used, results may be falsely elevated or falsely decreased due to biotin. The doctor may ask you to stop taking Viant before the laboratory tests. You should also be aware that other products you may be taking, such as multivitamins or supplements for hair, skin, and nails, may also contain biotin and affect the results of laboratory tests. Inform your doctor or laboratory staff if you are taking such products.

Pregnancy, breastfeeding, and fertility


If it is deemed necessary, Viant can be given during pregnancy, provided that attention is paid to the purpose of use and dosage to avoid an overdose of vitamin er.
The recommended daily dose should not be exceeded because high doses of vitamin A during pregnancy can cause malformations in the fetus.


Use of Viant is not recommended during breastfeeding. If you breastfeed during treatment with Viant, there is a risk of an overdose of vitamin A in the child.


There are no data on the effect of Viant on male or female fertility.

Driving ability and use of machinery

Viant has no or negligible effect on the ability to drive and use machines.

Viant contains sodium

This medicine contains up to 46 mg of sodium (the main ingredient in common/table salt) per vial. This corresponds to 2.3% of the maximum recommended daily intake of sodium for adults.

How Viant is given

The Viant powder is first dissolved in a liquid. It is then mixed with a larger amount of fluid ( parenteral nutrition solution, glucose, or electrolyte solution) before it is given to you. Viant will be given as a drip into a vein.

The recommended dose for adults and children from 11 years of age is 1 vial per day.

If you have been given too much Viant

If you have ingested too much medicine or if, for example, a child has ingested the medicine by mistake, contact a doctor or hospital for an assessment of the risk and advice.

The risk of vitamin overdose is greater if you receive other vitamin supplements or if the total supplement does not match your needs or if you already have an increased tendency to high vitamin levels (hypervitaminosis).

The most common symptoms of overdose are nausea, vomiting, and diarrhea. Symptoms of prolonged or acute vitamin E overdose may also include:

  • dry, scaly skin
  • headache, vomiting, and weakness
  • jaundice
  • increased pressure around the brain with symptoms such as headache, vomiting, confusion about time, and double vision
