IVs are used to help get liquid into people's systems faster than they could ingest the liquid. The needle gets inserted into the vein, so when saline or medications gets hooked up to the tubing attached to the needle, it goes right into the person's system. It's that speed that can make them medically necessary when it comes to saving lives. For example, if a person is severely dehydrated, hooking them into an IV and pushing saline into their system will rehydrate faster because the fluid gets into their body quicker and more fluid can get into the system at once. IV therapy is also used for other things. 

Hangovers

If you are dealing with a severe hangover, you can contact an IV therapy service. They can come to your house or you can go to their facility. When you see them, the provider will be able to give you an IV full of things like saline, vitamins, and other nutrients that can help your body fight off the effects of the hangover. The IV treatment can not only help you fight off your hangover, but by the time you've finished your treatment, you will likely feel better than before, because of the hydration and the extra vitamins that get pumped into your system.

You could also talk to the provider that you are working with to see if they can help you before you go out for a big bash, if they have any treatments that will help to prevent your hangover from starting, or from being as bad as it could otherwise be. 

Illness

If you have been dealing with something like the flu, or some other illness that has left you feeling just a little peaked as you are in the process of getting better, you might want to think about having an IV therapist come out to your house for you. They can help you start to recover the nutrition that you lost while you were sick. They can also give you extra vitamins to boost your energy up and speed up your final healing. 

IV therapy can do all kinds of things for you. It can help you in medical emergencies, but it could also help you in a more day to day way. An IV therapist may be able to come to your house to administer the medication to you, or you can go to their facility to get the same treatment.
