At the first sign of infection, it is often helpful to get a Vitamin C IV. It can sometimes prevent an infection from coming on or reduce the length of time you are sick. In people who get frequent colds or sinus infections, it may reduce the occurrence of infections. Vitamin C IV can be given in a Myers Cocktail, a 10 minute IV push or in larger doses as a bag or IV drip over 45-75 minutes. Vitamin C may lower blood sugar so you should be sure to eat before your treatment or bring a snack.
