After a consultation to determine the best course of IV Infusion, an IV line will be inserted into the arm which may feel like a slight pinch. During the treatment, vitamins and nutrients will slowly drip from the IV line and enter the bloodstream immediately to help the body begin healing itself. Depending on the type of infusion, this may take anywhere from 20 minutes to an hour. The infusion process is very comfortable and you should be able to sit back and relax until the infusion is completed.
