IV Say: iye-vee IV is actually short for intravenous (say: in-truh-vee-nus). Did you know you can get nourishment, fluids, and medicine through your veins? In some cases, it can be the best way to deliver the fluid or medicine that a person needs. IVs might be used if a person is having surgery, is very sick, or can't eat and drink normally. Whatever the reason, an IV can help the person get better again. Back to Articles Related Articles Note: All information is for educational purposes only.
