An IV infusion involves delivering fluids, vitamins, or medications into your bloodstream through a vein. It is a fast and efficient method that is often used to rehydrate the body, boost energy, or aiding nutrient deficiencies.

Generally, injections or IV therapy consists of intravenous medication administered intravenously to the patient. The injection uses a needle and  carried out on the patient's arms directly. It makes it much better for people with chronic illness as it directly injects antibiotic drugs and water into their bloodstreams.
