Intravenous therapy, also known as IV therapy, is a medical treatment involving delivering medication or other fluids directly into the bloodstream. IV therapy is often used to provide intravenous fluids, which can help to maintain hydration levels and provide essential nutrients.

Today, IV therapy is used to deliver other medications that help with many problems, from dehydration to insomnia, and even skincare-related medications or formulas. Delivery of these agents through IV helps the body absorb them faster and lets the body utilize these agents and medications quicker than other forms, such as over-the-counter prescriptions that are ingested or topical creams or gels.
