Infusion therapy delivers medication and nutrition directly into the veins, also known as intravenous or IV administration. Infusion therapy allows you to spend more time with friends and family in your own environment and less time in the hospital. With a decreased risk of infections, you are able to return to work or school more comfortably and safely. In addition, medical costs are lower because you receive care on a come-and-go basis rather than as part of a hospital stay.
