Who is eligible for IV therapy, and who is not

Eligibility for IV therapy is decided one person at a time, by a licensed provider who reviews your health history, and sometimes the answer is no. Cleveland Clinic advises that people seeing a provider for heart disease, high blood pressure, kidney disease or pregnancy generally avoid IV vitamin therapy.

How eligibility is decided

No website, quiz or price list can clear you. In Utah, a provider evaluating you by telehealth must obtain and document your relevant history and current symptoms and identify underlying conditions and contraindications, meaning reasons a service would not be appropriate.

That review looks at three things. Your conditions. Your medications. And the specific ingredients being considered, because a bag of fluids alone and a bag with added nutrients carry different cautions.

What follows is a general guide to the questions a provider weighs. It is not a checklist to clear yourself.

Heart, kidney and liver conditions

An IV adds fluid directly to the bloodstream. Some conditions limit how well the body handles that extra fluid.

Cleveland Clinic defines hypervolemia as having too much fluid in the body. Its listed causes include heart failure, kidney conditions and cirrhosis of the liver, and it notes that IV fluids can contribute. Symptoms include swelling, most often in the arms and legs, stomach bloating and quick weight gain. Serious signs include high blood pressure and shortness of breath.

This is why heart disease, high blood pressure and kidney disease sit on the list of reasons for caution. A provider may decline an IV, reduce the volume, or ask you to speak with your own doctor first.

Pregnancy

Pregnancy is on Cleveland Clinic's list of reasons to avoid IV vitamin therapy. If you are pregnant or may be, say so at intake. It changes the conversation.

Specific ingredients, specific cautions

Some cautions belong to the ingredient rather than to the IV itself.

Magnesium. The NIH Office of Dietary Supplements notes that the risk of magnesium toxicity rises with impaired kidney function, because the body's ability to remove excess magnesium is reduced or lost. Early signs can include low blood pressure, nausea, vomiting and flushing.

High-dose vitamin C. The National Cancer Institute states that people with G6PD deficiency, an inherited condition, should not be given high doses of vitamin C because it may cause hemolysis, the breakdown of red blood cells. It also notes that kidney failure has been reported after IV vitamin C in people with a history of kidney disease, that people likely to form kidney stones should not receive IV vitamin C, and that high doses are not recommended for people with hemochromatosis, an iron overload condition.

Vitamins in general. Cleveland Clinic notes that too much of a vitamin can cause nausea or dizziness and, at worst, serious harm. More is not better.

This is why a provider orders each add-in for you after reviewing your history and medications.

Medications

Some IV ingredients can interact with medications. Bring a complete list to your clearance, including supplements and anything taken only occasionally. Mayo Clinic also notes that diuretics and some blood pressure medicines increase urination, which matters when the reason for the visit is fluid loss.

When an at-home IV is the wrong setting

Some situations need an emergency room, not a visit at home. Call 911 or go to an emergency department if someone with signs of dehydration has pale, blue, grey or blotchy skin, lips or tongue, cold skin, difficulty breathing, confusion, or is unusually sleepy or hard to wake, which the NHS lists as possible signs of shock.

Mayo Clinic advises contacting a healthcare professional for diarrhea lasting 24 hours or more, being unable to keep fluids down, bloody or black stool, confusion, or a fever of 102 degrees or higher. These call for a diagnosis first.

What to have ready for your clearance

A short list makes the review faster and more accurate:

• your current conditions and past diagnoses;
• every medication and supplement, with doses;
• any allergies and any past reactions to an IV or injection;
• whether you are or may be pregnant;
• your own doctor's name, if you have one.

The clinical decision

A clearance may lead to a smaller volume, fewer ingredients, a conversation with your own doctor first, or no service that day.

At RESRV, a licensed nurse practitioner clears every client before a first service, and some people are not cleared. The steps are on how it works. For those who are cleared, the full menu lists every drip and price.
