The amount of a compound taken at one time, normally written as a weight such as micrograms or milligrams. A dose is a single event, and on its own it says nothing about how often that event repeats. Records here report the amount the source itself states, and where a source gives a range, or gives no amount at all, that is what you will see.

Why it matters here

Almost every claim about a compound is really a claim about a particular amount in a particular group of people, and changing the amount can change the result or remove it entirely. A record that names an effect but not the amount it was seen at cannot be lined up against any other record.

Also called

• dose
• dosage
• doseage
• dosis
• amount
• dose size
• single dose
• per dose
• how much
• dosing amount

Dosage is commonly used to mean the dose, though strictly it describes the whole regimen — amount, frequency and duration together. Everyday use treats the two words as interchangeable.
