What's the difference?

A medication error can be described as a mistake that happens with a medication. Examples include wrong dose, wrong person, or missing a known allergy to the medication.

We learn from all errors, even if you catch it before you take the medication, or if you do take it and it doesn’t cause any harm.

A reaction is an unwanted effect that happens when the medication is used as directed. Reactions are sometimes called side effects. Unlike a medication error, a reaction generally doesn’t involve a mistake and typically can’t be prevented. Examples include nausea, rash, sleepiness, cough, and can also be more serious like liver damage.
