Save Yourself From Plumbing Issues and Do Not Flush Your Tampon Down the Toilet 0 Shares Is it OK to flush a tampon down the toilet? It's a question you may have pondered while wrapping one up and tossing it into the trash can instead. While it may seem harmless (and would theoretically save you a few sheets of toilet paper), flushing your tampon down the toilet is generally not a good idea. For starters, it's a potential recipe for plumbing problems. Popular tampon brands such as Lola, Tampax, Kotex, and Natracare all note not to flush tampons down the toilet, as the act could result in a clogged or overflowing toilet or a blockage in the plumbing or septic system. Even if you haven't dealt with this issue at home, there's a chance you've seen the unfortunate result of a tampon clog in a public restroom.
