About National Adverse Drug Event Awareness Day

National Adverse Drug Event Awareness Day is observed on March 24 as an American Society of Pharmacovigilance-led medication-safety awareness campaign.

ASP announced the observance on March 24, 2021 and has continued to use the date in later annual campaigns.

Why National Adverse Drug Event Awareness Day matters

The day focuses attention on adverse drug events, medication safety and systems for recognizing and reporting safety problems.

Awareness material is not a substitute for clinical advice. A public observance page should not diagnose an adverse drug event, tell someone to stop or change medication, or treat campaign statistics as individualized risk.

History of National Adverse Drug Event Awareness Day

On March 24, 2021, ASP announced that it was establishing March 24 as National Adverse Drug Event Awareness Day and launching an awareness campaign.

ASP described the 2024 observance as the third annual National Adverse Drug Event Awareness Day and continued the campaign in 2026, when its material described a fifth annual observance.

Those ordinal references support continuing annual use of March 24, but the guide does not infer a separately documented first completed annual edition when the reviewed sources primarily document the 2021 launch and later numbering.
