What is the adult dose for metoclopramide?

• A. 5 mg
• B. 10 mg
• C. 15 mg
• D. 20 mg

Answer: (B)

Metoclopramide’s purpose here is to control nausea and vomiting in adults with a dose that provides reliable relief while limiting side effects. The standard adult dose is ten milligrams, given by IV over one to two minutes or by intramuscular injection, and it can be repeated if the protocol allows. This amount is chosen because it offers effective antiemetic action without as much risk of extrapyramidal reactions or excessive sedation that higher doses can bring. A smaller dose like five milligrams may be less effective, while higher doses such as fifteen or twenty milligrams increase the likelihood of adverse effects.
