From the Guidelines

The recommended dosing for a Gastrointestinal (GI) cocktail in adults is not explicitly stated in the provided evidence, but based on general medical knowledge, a GI cocktail typically includes a combination of medications such as antacids, antiemetics, and analgesics.

  • A common combination includes:
    • Antacids such as Maalox (aluminum hydroxide, magnesium hydroxide, and simethicone) 10-20 mL orally 1
    • Antiemetics such as metoclopramide 5-10 mg orally or intravenously
    • Analgesics such as lidocaine 10-20 mg orally or intravenously
  • The frequency of administration may vary depending on the individual's symptoms and response to treatment, but it is typically given every 4-6 hours as needed.
  • It's essential to use caution and consider the potential side effects and interactions of each medication when prescribing a GI cocktail, such as headache, diarrhea, constipation, and abdominal pain 1.
  • The choice of medication and dosing should be individualized based on the patient's specific needs and medical history.

From the Research

Gastrointestinal (GI) Cocktail Dosing in Adults

The recommended dosing for a GI cocktail in adults is not explicitly stated in the provided studies. However, the studies provide information on the common combinations and ingredients used in GI cocktails:

  • A study from 2003 2 compared three combinations of medications for dyspepsia symptoms: antacid, antacid + Donnatal, and antacid + Donnatal + viscous lidocaine.
  • A study from 1995 3 described the practice patterns regarding administration of the "GI cocktail" in the emergency department, which typically includes a mixture of liquid antacid, viscous lidocaine, and an anticholinergic.

Ingredients and Combinations

The ingredients and combinations used in GI cocktails vary, but common components include:

  • Liquid antacid
  • Viscous lidocaine
  • Anticholinergics (such as Donnatal)
  • Other medications like narcotics, nitroglycerin, antiemetics, H2-blockers, and aspirin may be coadministered with the GI cocktail 3

Dosage Information

While the studies do not provide specific dosage recommendations for GI cocktails, they do report on the dosages used in certain contexts:

  • A study from 2021 4 reported that patients received haloperidol 1.1 ± 0.3 times with a dose of 2.5 ± 3.0 mg, mostly intravenously, for gastrointestinal symptoms.
  • A study from 2010 5 discussed the use of antiemetic agents, including droperidol, promethazine, prochlorperazine, metoclopramide, and ondansetron, but did not provide specific dosage information for GI cocktails.

Safety Considerations

The use of GI cocktails and their ingredients should be approached with caution, particularly in older adults, due to the risk of injury associated with antispasmodic and anticholinergic medications 6.
