Can A Myers' Cocktail Help Me?

What is a Myers’ cocktail?

At least 40% of adults in the U.S. use some form of complementary or alternative medicine therapy, including vitamins and dietary supplements. While many people use oral vitamins and over-the-counter supplements bought from pharmacies, the use of intravenous (IV) vitamin and hydration therapies has increased in popularity in recent years. Intravenous vitamins and hydration are claimed to treat hangovers, help fight off infections, prevent aging, and enhance athletic performance. These treatments are frequently offered by medical spas and clinics. Sometimes, intravenous treatments can even be administered in hotel rooms, buses, or airports.

A Maryland doctor named Dr. John Myers was one of the first physicians to promote the use of intravenous nutrient therapy. Unfortunately, Dr. Myers did not keep detailed written records about what his treatments included, so the actual ingredients used in his intravenous nutrient therapy recipes remain unknown to this day. After he died in 1984, one of his colleagues took over the care of many of his patients and developed an intravenous nutrient therapy regimen that he named the “Myers’ cocktail” in honor of the late Dr. Myers. The ingredients in this regimen included intravenous magnesium, calcium, several B vitamins, and vitamin C. The ingredients are not standardized, and variations of this formulation are still used by many holistic or alternative medicine practitioners to treat various conditions, including chronic fatigue, fibromyalgia, depression, and migraine headaches.

How effective are Myers’ cocktails?

Despite the increasing use of intravenous nutrient therapy and the abundance of clinics offering these products, there is limited evidence that these treatments provide any clinical benefit. Very few medical studies have evaluated the effectiveness of Myers’ cocktails. In one study of the use of a Myers’ cocktail in fibromyalgia patients, there were no significant differences in clinical outcomes in patients who received the Myers’ cocktail versus those who received a placebo. In another study of the use of a Myers’ cocktail in fibromyalgia patients, many patients reported having increased energy levels within 1–2 days of receiving the cocktail, but no patients had complete resolution of pain or fatigue. Overall, the Myers’ cocktail has not been proven to effectively treat any medical condition.

Do Myers’ cocktails have any side effects?

Despite the lack of evidence, some medical clinics promote the Myers’ cocktail as a definitive medical treatment. The U.S. Federal Trade Commission has ordered at least one company to stop marketing their intravenous nutrient therapies as a treatment for cancer, multiple sclerosis, and heart failure. The use of intravenous nutrient therapies, including the Myers’ cocktail, can be harmful to some people. Adverse events, including a sense of warmth, muscle cramps, low blood pressure, and fainting, can occur after Myers’ cocktail administration. The vitamins and electrolytes included in the Myers’ cocktail might interact with prescription medications, causing potentially life-threatening conditions. As with any intravenous medical therapy, there are risks of allergic reactions, infections, and irritation related to IV placement. In addition, although vitamins are natural and perceived as safe, they can be poisonous when taken in large amounts. 

Because of these potential undesirable side effects, intravenous therapies should ideally be provided in a hospital or other traditional medical setting. In the U.S., intravenous hydration solutions, including vitamins and minerals, are regulated as prescription drugs and must be prescribed by a licensed medical professional. In some clinics or medical spas, that licensed medical professional might be the clinic’s medical director, who has limited or no involvement with the patients. In some cases, the medical director might not be physically present in the clinic.

What are alternatives to Myers’ cocktails?

For people who prefer to use complementary and alternative medicine, there are safer and more effective alternatives to the Myers’ cocktail. Acupuncture, yoga, and mind-body practices are generally safe and can have beneficial effects on medical conditions, including pain. Integrative medicine, which combines the techniques of both conventional and alternative medicine, is another option for people who are searching for additional ways to improve their health and wellbeing.
