Intravenous (“IV”) hydration therapy is the administration of intravenous fluids, vitamins, minerals and other nutrients. It is a therapy that delivers liquid substances directly into a vein by inserting a needle and infusing over a period of time. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body, because the circulation carries them. Intravenous therapy may be used for fluid replacement (such as correcting dehydration), to correct electrolyte imbalances, to deliver medications, and for blood transfusions.
