Intravenous treatment, also known as IV therapy, involves delivering medication or fluids directly into a person's bloodstream through a vein. This method allows for rapid and effective absorption of the treatment into the body, making it a common choice for administering medications in emergency situations or for individuals who are unable to take medications orally. IV therapy is used in a variety of medical settings, including hospitals, clinics, and ambulatory care facilities, and can be used to treat a wide range of conditions such as dehydration, infections, and chronic diseases.
