IV hydration therapy is a common, low-risk procedure used by a nurse to rehydrate the body intravenously, bypassing the gastrointestinal tract. It is the fastest, most efficient delivery method to distribute vital fluids & nutrients throughout your body.  Intravenous (IV) fluid drips deliver a combination of saline solution, vitamins, electrolytes and medications through a small catheter and tubing directly into the bloodstream. The ingredients in individual IV formulas are specifically blended to address a variety of health needs.
