P&G is the maker of Tampax, one of the top-selling tampon brands in the US. They hired Schumer, 41, in 2020, for an ad campaign about "How to Insert a Tampon." The 33-second video shows the comedian inserting a tampon into a donut and then taking a bite of the pastry. She then discusses the tampon with a doctor in what appears to be a medical setting.

P&G spokeswoman Cheri McMaster told Time magazine that feminine care products "sales growth has exploded" since the comedian was hired to do a series of commercials nearly two years ago. 

Located in Auburn, Maine is P&G's only Tampax factory. McMaster claims the facility operates around the clock to keep up with the demand

However, TIME's Alana Semuels pointed out: "But I find it a little hard to pin the tampon shortage on Amy Schumer."
