IV Therapy for Hangovers — Does It Actually Work?

The hangover IV is one of the most-Googled IV therapy treatments in the world. The honest answer is yes, it works — but the mechanism matters, and there are situations where it''s overkill.

What a hangover actually is

A hangover isn''t just dehydration. Alcohol triggers at least six measurable physiological effects:

• Diuresis — alcohol suppresses vasopressin, causing your kidneys to dump water and electrolytes
• B-vitamin depletion — particularly B1, B6, and B12, which your liver burns through metabolizing alcohol
• Magnesium depletion — flushed out alongside the fluid loss
• Acetaldehyde toxicity — alcohol metabolizes to acetaldehyde, which is more toxic than alcohol itself
• Glutamate rebound — causes anxiety, jitteriness, and disrupted sleep
• Inflammation — alcohol triggers a measurable systemic inflammatory response

A hangover IV addresses several of these at once.

What oral hydration can''t do

You absorb maybe 250mL of fluid per hour from the gut, and that absorption slows further if you''re nauseated. A litre of IV fluids enters your bloodstream in 30 minutes regardless of how your stomach feels.

What''s actually in a hangover IV

• 1 litre of saline or Lactated Ringer''s
• B-complex (B1, B2, B3, B5, B6)
• B12
• Magnesium
• Vitamin C
• Optional: ondansetron (Zofran) for nausea — $25 to $50 add-on
• Optional: ketorolac (Toradol) for headache — IV NSAID, much faster than ibuprofen

Most people feel relief within 15 to 20 minutes of the drip starting.

When the IV is genuinely worth it

• You''re vomiting and can''t keep fluids down
• You need to function — flight, big meeting, wedding, event
• You''re severely dehydrated
• You drink rarely so the $200 to $300 is an occasional splurge
• You''re traveling and a mobile service can come to your hotel room

When you should skip the IV

• Mild hangovers where oral hydration works fine
• You''ve already been steadily drinking water and feel okay
• Cost is a real concern and you have a free afternoon to recover

What it costs

Standard hangover IVs run $150 to $350 in most US and Canadian cities. Mobile service typically adds $50 to $100. Cities with heavy hangover demand — Las Vegas, New York, Miami — sit at the higher end. See our IV therapy cost guide for a full breakdown.
