A Myers’ Cocktail is an IV drip of magnesium, calcium, vitamin C and B vitamins in IV fluid. At Rock Creek Wellness in Leawood, in the Kansas City area, ours costs $175 and takes about an hour. It’s given only after one of our providers has seen you and prescribed it. Below is every ingredient and dose, what the research shows, and what to expect. Individual results vary.

What is a Myers’ Cocktail?
The drip is named for John Myers, MD, a Baltimore physician who gave vitamins and minerals by IV to his patients for many years. He never published his formula. After his death, another physician, Alan Gaby, MD, published a modified version in 2002. Today’s Myers’ Cocktails, including ours, share the same core: magnesium, calcium, vitamin C and B vitamins.
Does a Myers’ Cocktail work?
It does put its ingredients straight into your bloodstream. Whether that helps healthy people feel or function better hasn’t been shown.
- The only placebo-controlled trial. In a small trial in 34 adults with fibromyalgia, people improved with both the Myers’ Cocktail and a placebo drip, with no significant difference between the two.
- Healthy people. A 2025 review found that the reported results of IV vitamins in healthy people come mostly from anecdotes and self-reports, not from well-designed randomized trials.
- Professional caution. In 2024, the American College of Clinical Pharmacology concluded that there is little to no evidence that the gains from vitamin infusions outweigh their risks. It recommends them only with a physician’s approval for a valid medical reason.
So we won’t promise that you’ll feel different afterward. We’ll look at your history, medicines and goals, and tell you honestly whether a Myers’ Cocktail makes sense for you, or whether food or an oral supplement would do the same job.
Will a Myers’ Cocktail hydrate you?
It gives you fluid, because it’s given in IV fluid that goes straight into your bloodstream. For mild dehydration, though, drinking water or a sports drink with electrolytes works for most people. An IV makes the most sense when you can’t keep fluids down.
If someone who is dehydrated becomes confused, faints or has a seizure, call 911 or go to an emergency room, not an IV clinic.
Who it’s for and who it isn’t
The Myers’ Cocktail is for adults aged 21 and over who want vitamins and minerals by IV, after a consultation with one of our providers, and who understand what the research does and doesn’t show.
It isn’t for everyone:
- Pregnancy. We don’t give IV infusions to pregnant women, and we don’t take on new patients who are pregnant or breastfeeding.
- Heart, kidney or liver disease, or high blood pressure. Extra fluid and minerals can strain your heart and kidneys. Your kidneys clear magnesium, so kidney disease can let it build up.
- Your other medicines. Some vitamins and minerals interact with medications, so tell us about everything you take, including supplements.
- Athletes who are drug-tested. Anti-doping rules prohibit IV infusions of more than 100 mL in 12 hours outside hospital care, unless you have an approved exemption. Check with your anti-doping agency first.
Your provider goes through all of this with you and will tell you if a Myers’ Cocktail isn’t a good idea for you.
What to expect at your visit
- Consultation first. One of our providers sees you: your own provider if you’re already our patient, and usually our nurse practitioner, Hannah Osborn, APRN, if you’re new. They go through your health history, medicines and goals, decide whether an IV makes sense for you and which one, and write a prescription for you. The consultation is free.
- Vital signs. We check your blood pressure, pulse and other vital signs before the IV starts and again when it ends.
- The infusion. Our nurse practitioner, Hannah Osborn, APRN, places the IV in your arm and looks after you while it runs, which takes about an hour. You’ll feel a brief pinch when the IV goes in. After that, you can read, work or rest.
- Afterward. You can usually go straight back to your day.
A Myers’ Cocktail costs $175. It’s cash-pay and isn’t covered by insurance. We accept HSA and FSA cards; your plan decides what qualifies. Premier Care members receive their member discount.
How we prepare and give every IV, and the Kansas rules behind it, are on our IV therapy page.
Risks and side effects
- Warmth or flushing. The magnesium can cause a feeling of warmth, especially if the drip runs fast. We run it at a comfortable pace. Tell us if the warmth bothers you and we’ll slow it down.
- The IV site. Any IV can cause bruising, soreness or irritation of the vein. Less often, the site becomes infected or a blood clot forms.
- Fluid and minerals. Too much fluid, or too much of a mineral, can upset your body’s balance of salts and strain your heart and kidneys.
- Allergic reactions can happen and, rarely, can be severe.
- The days after. Call us if the IV site becomes red, hot, swollen or more painful, or if you get a fever.
Common questions
How much does a Myers’ Cocktail cost?
At our clinic, $175 per infusion. It’s cash-pay; we accept HSA and FSA cards.
How long does it take?
About an hour.
How often can I have one?
There’s no evidence-based schedule. Your provider decides with you, based on your reason for having one and your health.
Is an IV better than taking vitamins?
For most people, there’s no evidence that it is. An IV reaches higher blood levels of some vitamins for a few hours, and it skips your stomach. But your kidneys clear the extra within hours, and studies haven’t shown better results in healthy people. Our IV therapy page explains what’s actually different between IV and oral vitamins.
Does it hurt?
You’ll feel a brief pinch when the IV is placed. After that, you can read, work or rest.
Can I ask for a Myers’ Cocktail?
Yes. Tell us what you’re interested in. Your provider decides whether it’s right for you after seeing you, and sometimes the answer is that you don’t need an IV at all.
