Intravenous means occurring within or by way of a vein. Medicines or fluids may be given by inserting an intravenous (IV) needle into a vein, usually in the back of the hand or on the forearm.

When the IV needle is in place, medicines or fluids can go quickly into the bloodstream and into the rest of the body.
