Intravenous (IV) therapy, also known as intravenous infusion therapy, is a medical treatment that involves delivering fluids, medications, nutrients, or other substances directly into the bloodstream of a patient through a vein. This method allows for quick and precise delivery of these substances, bypassing the digestive system and allowing for rapid absorption by the body. IV therapy is commonly used in healthcare settings for various purposes, such as hydration, pain management, administering chemotherapy, antibiotics, and nutritional support. It is often used when oral medications or other methods are not practical or effective, to ensure that the treatment reaches the bloodstream quickly for maximum therapeutic effect. Trained healthcare professionals usually administer IV therapy to guarantee safety and efficacy.
