Is Rinsing Your Sinuses Safe?
FDA has concerns about the risk of infection tied to the improper use of neti pots and other nasal rinsing devices. The agency is informing consumers, manufacturers and health care professionals about safe practices for using all nasal rinsing devices.
Most important is the source of water. Some tap water contains low levels of organisms, such as bacteria and protozoa, including amoebas, which may be safe to swallow because stomach acid kills them. But these “bugs” can stay alive in nasal passages and cause potentially serious infections, according to the Centers for Disease Control and Prevention (CDC).
Improper use of neti pots may have caused two deaths in 2011 in Louisiana from a rare brain infection that the state health department linked to tap water contaminated with an amoeba called Naegleria fowleri.
