From the Guidelines

To address thirst and hangover symptoms, start by rehydrating with water or electrolyte-containing beverages like sports drinks or coconut water, aiming for at least 16-32 ounces of fluid over the next few hours, as recommended by recent studies 1, 2. When considering the best approach to manage hangover symptoms, it's essential to prioritize rehydration. The most recent and highest quality studies suggest that drinking water or electrolyte-containing beverages is crucial for replenishing lost fluids and electrolytes 1, 2. Some key points to consider when rehydrating include:

  • Drinking at least 16-32 ounces of fluid over the next few hours
  • Choosing electrolyte-containing beverages like sports drinks or coconut water
  • Eating easily digestible foods like toast, crackers, or bananas to help stabilize blood sugar levels
  • Limiting caffeine consumption, as it can contribute to dehydration, although a small amount may help with headache symptoms 2
  • Avoiding aspirin, as it may irritate the stomach, and instead opting for over-the-counter medications like ibuprofen (Advil, Motrin) at a dose of 400mg or acetaminophen (Tylenol) at a dose of 500-1000mg, following package directions It's also important to note that hangovers occur due to alcohol's diuretic effect, causing dehydration, and its breakdown producing acetaldehyde, a toxic compound contributing to symptoms like headache and nausea. For future reference, drinking water between alcoholic beverages and eating before drinking can help prevent hangovers. Additionally, studies have shown that coffee and alcoholic drinks with up to 4% alcohol content do not cause dehydration 2.

From the Research

Hangover Relief

  • Hangovers are often characterized by dehydration and electrolyte imbalances, which can be alleviated with proper fluid and electrolyte therapy 3.
  • Intravenous (IV) electrolyte replacement can help restore fluid balance, but it may also contribute to a positive fluid balance, which can be detrimental in some cases 4.

Fluid and Electrolyte Therapy

  • The choice of IV fluid and electrolyte therapy depends on the individual's specific needs and medical condition 3.
  • IV electrolyte replacement can be beneficial in critically ill patients, but it is essential to monitor fluid balance and adjust therapy accordingly 4.

Pain Relief

  • Intravenous ibuprofen can be effective in reducing pain and fever in adults, and it may be used as an adjunct to other pain management therapies 5.

Hydration

  • Both intravenous and oral hydration can be effective in preventing dehydration and electrolyte imbalances, but the choice of approach depends on the individual's specific needs and medical condition 6.
  • Urine output is an essential factor in determining the effectiveness of hydration therapy, and it can be used to monitor the incidence of contrast-associated acute kidney injury (CA-AKI) 6.
