Intravenous (IV) infusion is a medical term that describes the way certain kinds of medicines or other substances are delivered to the body.
While many medicines or things like fluids can be taken orally, sometimes this is not an option due to time concerns or the need to bypass the gut and get medicines or other treatments directly into the veins.
In these circumstances doctors and/or nurses can establish a small IV goes directly into a vein, and they use this line for drug or other substance delivery.
Many medications are delivered in this manner at hospital settings, at certain treatment centers, and sometimes at home.
