Women face another product shortage: tampons

Supply-chain snarls are hitting the feminine care aisle, with women venting on social media about how hard it is to find tampons in stores right now. 

On Twitter, #tamponshortage is trending, with some users calling it the latest "nightmare" for women after the Food and Drug Administration acknowledged widespread shortages of baby formula. Individuals and not-for-profit groups that collect donated feminine care products are also complaining of empty shelves where the monthly essentials are usually stocked.

"I thought I was going crazy noticing empty shelves where tampons should be," one Twitter user said.
