Who Should Avoid IV or IM Nutrient Therapy?
An injection or infusion may be inappropriate, unnecessary or require modification depending on the ingredients, route, dose and patient’s health.

Situations requiring careful review
- Pregnancy or breastfeeding
- Kidney, liver or heart disease and fluid restrictions
- G6PD deficiency, iron overload or kidney-stone history for certain vitamin C plans
- Active infection, fever or skin infection at the injection site
- Severe allergy or previous infusion reaction
- Anticoagulant use or bleeding disorders for IM injections
- Implanted access devices or difficult venous access
- Active cancer treatment or complex specialist-managed illness
Safety and evidence
The list is not exhaustive. A person can be unsuitable even without a listed condition, and a different route or oral option may be safer. Delay elective wellness therapy when acutely ill unless the treating clinician advises otherwise.
