Intravenous therapy, commonly known as IV therapy, is a medical technique where fluids, medications, or nutrition are administered directly into the veins. The use of IV therapy is widespread in hospitals and clinics since it is an effective way to deliver medication quickly through the bloodstream. There are several synonyms for the term "intravenous therapy," including IV infusion, IV drug therapy, IV medication, and venous access therapy. Regardless of the name used, IV therapy offers a rapid and reliable way to deliver necessary substances into the body. It is essential for various medical conditions such as dehydration, chemotherapy, and critical care.
