Can vitamin D be given in a drip?
Solubility, vehicle
and why formulation determines route
Short answer. The vitamin D3 preparation used at MediBalans is oil-based and intended for intramuscular administration. It must not be added to an aqueous IV drip. Other vitamin D metabolites and specialist formulations exist in other medical settings.
Route must be tied to the specific substance, formulation, vehicle, compatibility information and medical prescription.
Solubility
A fat-soluble substance in
an aqueous solution
Water or fat solubility affects how a substance must be formulated, but it does not alone determine whether a product can be given intravenously. For parenteral medicines, the specific product information, vehicle, compatibility and prescription govern the route.
Cholecalciferol is lipophilic. The product used at MediBalans is formulated in oil and labelled for intramuscular administration. It must not be diluted into an aqueous infusion bag or given intravenously.
Fat-soluble vitamins can occur in specially formulated parenteral products, for example in parenteral nutrition. Those products have their own vehicles, indications and handling instructions and are not equivalent to the MediBalans vitamin D3 injection.
What actually exists
Parenteral vitamin D exists —
in specific products and indications
It would be wrong to claim that every form of vitamin D can never be given intravenously. Route and indication depend on the specific substance and product.
Lipid emulsion. In parenteral nutrition there are vitamin preparations in which the fat-soluble vitamins are formulated in a lipid emulsion. That is a nutritional medicine for patients who cannot absorb nutrition enterally, with its own indications and its own monitoring — not an additive to a wellness drip.
Calcitriol. The active metabolite 1,25-dihydroxyvitamin D exists in intravenous form for specific medical indications, including in nephrology. Calcitriol is not the same product as cholecalciferol and requires different prescribing and monitoring.
The useful follow-up question: which substance, product and route are meant? Cholecalciferol, calcitriol and vitamin formulations for parenteral nutrition are not interchangeable.
Route of administration
The oil is the vehicle —
and that is why it is intramuscular
The 100,000 IU preparation used at MediBalans is oil-based and intended for intramuscular injection. It acts as a depot, but the change in 25(OH)D and the appropriate interval vary between individuals.
The oil-based IM product must not be given intravenously. The wrong route can cause serious harm, so product information and the physician's prescription determine how it is given. The route is part of the preparation's safety profile, not a formality.
MediBalans does not offer a D3 injection if the patient already takes vitamin D3 tablets or capsules. The physician considers baseline level, risk factors, alternatives and the need for follow-up.

The same principle
The right thing, in the right form,
by the right route
This is the same transparency that governs the rest of our IV/IM service. We state glutathione as 600 mg reduced GSH and vitamin D3 as an oil-based intramuscular preparation.
In every case, the substance, product, dose and intended route must be stated clearly. The physician then decides whether treatment is medically appropriate.
Frequently asked questions
Questions about vitamin D
and drips
The vitamin D3 preparation used at MediBalans is oil-based and intended for intramuscular administration. It must not be given in an aqueous IV drip. Other vitamin D metabolites and specialist formulations exist in specific medical settings.
Yes. Vitamin formulations for parenteral nutrition and intravenous calcitriol are used in specific medical settings. They are not the same product or treatment as the oil-based vitamin D3 injection used at MediBalans.
The oil-based 100,000 IU preparation is labelled for intramuscular injection. It acts as a depot, but the change in 25(OH)D and the appropriate dosing interval vary and are assessed by the physician.
An oil-based IM product must not be given intravenously. The wrong route can cause serious harm. Product information and the physician's prescription therefore determine how it is given.
Ask which substance, product and route are meant. Cholecalciferol, calcitriol and vitamin formulations for parenteral nutrition are not interchangeable and are used in different medical settings.
MediBalans offers vitamin D3 100,000 IU as an intramuscular injection, not as part of a drip. The price is 449 SEK. Book directly; Christina Biri performs the safety check on arrival and may change or decline treatment.
