Intravenous means “administered through the veins .” An IV drip usually consists of an IV bag, a hollow needle, and a long tube that leads from the bag to the needle.
The therapy part refers to what the bag administers into the veins. In the case of IV vitamin therapy, the bag delivers fluid that contains vitamins, minerals, and other nutrients directly into your bloodstream. In addition, when it’s for medical IV treatment, the fluid may also contain medication.
