As the person who developed the intravenous nutrient infusion that is now called the Myers cocktail, I believe certain comments are in order regarding your article, "Baltimore-area clinics are offering vitamin IVs. But do you really need one?” (Feb. 15). When Dr. John Myers, a Baltimore physician, died in the 1980s, I took over the care of patients who had been receiving IV nutrients. To conform to more recent research, I modified the ingredients and dosages used by Dr. Myers, and the infusion was named the "Myers cocktail" in his honor. During 15 years of medical practice in Baltimore, about 15,000 Myers cocktails were administered in my office. This treatment can knock out acute asthma attacks and acute migraines in most cases within two minutes. One patient suffering acute morphine withdrawal become symptom-free within 5 minutes of receiving this treatment. Other conditions that improved included congestive heart failure, chronic fatigue, respiratory infections and fibromyalgia. Intravenous magnesium has been well-documented by medical research to be effective for acute asthma and acute migraines, but clinical experience suggests that a combination of nutrients works better than magnesium alone.
