Intravenous infusion therapy involves administering fluids, medications, or nutrients directly into the bloodstream through a vein. This method allows for rapid absorption and distribution throughout the body, making it effective for delivering treatments such as antibiotics, chemotherapy drugs, or hydration solutions. Intravenous infusion therapy is commonly used in hospitals, clinics, and home care settings to treat various conditions ranging from dehydration to chronic illnesses. It provides a precise and efficient delivery method for medications and fluids.
