IV basics

What is IV hydration therapy?

What goes into an IV, how a visit works, and what IV hydration can and can’t do, in plain English.

The short version

IV hydration therapy puts sterile fluid, electrolytes, and sometimes vitamins or medications straight into a vein through a small, flexible catheter. Because it skips the digestive system, fluid reaches your bloodstream right away instead of being absorbed gradually through the gut.

Key takeaway: The well-established benefit of an IV is fluid replacement. If you can drink and keep fluids down, drinking usually works too. See oral vs. IV hydration.

How it works

A nurse cleans the skin, places a thin catheter (usually in the forearm or hand), and connects it to a bag of fluid. Gravity or a pump controls the drip rate. Most drips take 45 to 60 minutes. When the drip is done, the catheter comes out and a small bandage goes on.

What's in a drip

  • Base fluid: normal saline or lactated Ringer’s, usually 500 mL to 1 L. Both contain electrolytes such as sodium, chloride, and potassium.
  • Vitamins: commonly B-complex, B12, and vitamin C.
  • Minerals: commonly magnesium, calcium, and zinc.
  • Medications when clinically appropriate and ordered by a physician: for example, anti-nausea medicine.
  • Specialty add-ins: glutathione, NAD+, taurine, and others.

Our ingredient guide covers what each one does.

Why people choose it

  • Recovering from a stomach bug or food poisoning when drinking is hard
  • Texas heat, outdoor work, sports, or long shifts
  • Travel and jet lag
  • The morning after a celebration
  • An ongoing wellness routine

What it can't do

IV hydration doesn’t cure disease, “detox” your body, or replace care from your doctor. Research on vitamin infusions for specific conditions is limited, and the studies that exist are mostly small. A good provider will be upfront about that.

Go to the ER or call 911 instead if you have chest pain, trouble breathing, confusion, fainting, a high fever, blood in your vomit or stool, or you can’t keep any fluids down for many hours.

What an at-home visit looks like

With a mobile provider like Medic Mantra, a licensed RN or paramedic comes to your home, hotel, or office. They review your health history, take your vital signs, start the IV, stay with you for the whole infusion, and take every supply away when they leave.
