About National Tampon Day
National Tampon Day is a privately created menstrual-product awareness observance held on May 12.
National Day Archives identifies TOP, The Organic Project, as the 2020 founder, and TOP co-founder Denielle Finkelstein later publicly stated that TOP founded the day in 2020.
Why National Tampon Day matters
The observance was created by a menstrual-product brand to reduce stigma around periods and promote discussion of menstrual products. Its commercial origin should be kept distinct from independent health and product-safety guidance.
FDA guidance—not brand marketing—should be used for tampon safety. Product claims such as “organic,” “natural” or “free from” do not by themselves establish comparative medical safety.

National Day Archives lists May 12, identifies TOP as founder in 2020 and describes the first National Tampon Day promotion.
In a 2021 first-party post, TOP co-founder Denielle Finkelstein said TOP founded National Tampon Day in 2020.

How to Observe National Tampon Day
Use the day to learn about menstrual health and product options without shaming anyone’s product choice or menstrual experience.
For tampon use, follow the product label and current FDA safety guidance, including changing tampons within recommended time limits.
Use the lowest absorbency that meets your needs and do not use tampons when you are not menstruating, consistent with FDA guidance.
Know that sudden fever, vomiting, diarrhea, dizziness/fainting or a sunburn-like rash while using tampons can be warning signs requiring prompt medical attention.
Do not treat brand-origin claims or “organic” labeling as proof that one product is medically safer than another.
