Myers Cocktail is a sterile premixed injection that combines key vitamins and minerals often used to correct short-term nutrient gaps, support normal energy production, and promote healthy immune function. Each 10 mL single-dose vial contains a balanced blend of magnesium chloride, calcium gluconate, ascorbic acid, B-complex vitamins, and hydroxocobalamin B12. The solution is intended for slow intravenous (IV) administration only under the supervision of a licensed healthcare professional. By delivering nutrients directly into the bloodstream, the formulation avoids losses that can occur in the digestive tract and allows rapid achievement of targeted blood levels. This product is preservative-free.

Clinical information
Medication information for patients and providers.
Use only as directed by your healthcare provider. The provider will decide the dose, dilution, and infusion rate based on your individual needs. If you miss a scheduled IV session, call the clinic to reschedule. Do not attempt self-administration. Do not double up doses.
The nutrients in this IV solution work together to support normal cell function. Magnesium and calcium help muscles and nerves fire correctly. B-complex vitamins act as helpers in the body’s energy pathways, turning food into usable fuel. Vitamin C serves as an antioxidant and supports white blood cells. Hydroxocobalamin B12 aids red blood cell formation and nerve health. Because the solution goes straight into a vein, it starts raising blood levels within minutes; most people notice improved energy or hydration within 30–60 minutes. Effects typically last a few days, but this can vary by person and lifestyle.
Do not use if you are allergic to any ingredient in this product. Do not use if you have high blood calcium (hypercalcemia) or high blood magnesium (hypermagnesemia). Avoid if you have severe kidney disease that limits the body’s ability to clear minerals. Not for use in infants or children. Tell your provider if you are pregnant, planning to become pregnant, or breastfeeding; the benefits and risks must be weighed carefully.
Calcium and magnesium may interact with certain heart medicines such as digoxin or calcium channel blockers, increasing risk of rhythm problems. Large doses of vitamin C can affect blood sugar readings on home glucose meters and may increase absorption of iron supplements. Vitamin B6 can lessen the effect of some seizure medicines like phenytoin and phenobarbital. Tell your provider about all prescription drugs, over-the-counter medicines, herbal products, and alcohol use before each infusion.
Very common (more than 1 in 10 people): mild warmth or metallic taste during infusion; usually ends within minutes. Common (1–10 in 100 people): temporary flushing, lightheadedness, or nausea; these normally resolve shortly after the infusion stops. Uncommon (1–10 in 1,000 people): vein irritation, bruising at the IV site, headache. Rare but serious: allergic reaction with rash, itching, swelling of face or throat, or trouble breathing—seek emergency care. Rapid infusion can cause low blood pressure or fainting; slowing the drip usually helps. Report any side effects that bother you or do not go away.
Refrigerate at 36–46 °F (2–8 °C). Keep the vial in the original carton to protect from light. Do not freeze. Do not shake. Once removed from refrigeration, use within 4 hours or discard. Check the solution before use; do not use if cloudy, leaking, or past the beyond-use date. Dispose of unused product and used IV supplies through a medical waste program; do not flush or place in household trash.
Frequently asked questions.
Most providers run the 10 mL vial over 15–30 minutes, often diluted in 250–500 mL of normal saline. Your exact time may vary based on vein size and comfort.
Many people notice more energy or clearer thinking within an hour. Others may feel gradual improvement over the next day as hydration and nutrient levels stabilize.
Yes, most patients can drive, but wait 10–15 minutes after the IV to be sure you are not dizzy. Arrange a ride if you feel lightheaded or if your provider advises it.
Frequency depends on your health goals and lab values. Some people get a boost once a month, while others need weekly sessions during times of stress. Follow your provider’s plan.
Usually yes, but high doses can pile up. Bring a list of all supplements and medications so your provider can adjust the IV or oral products to safe levels.
Apply gentle pressure with a clean cotton pad for a minute after the needle is removed, and keep the arm elevated for a short time. A cool compress at home can also help.
