DR. PAUL KOELLIKER answers this week’s question:

“ARE NETI POTS DANGEROUS?”

You might first ask, what is a neti pot?

Neti pots are tools used for nasal irrigation, the personal hygiene practice in which the nasal cavity is washed to flush out excess mucus and debris from the nose and sinuses.

A neti pot flushes out nasal passages

Nasal irrigation is an effective means of clearing mucous from the nasal-pharynx. There is evidence that shows that regular nasal irrigation with saline may decrease upper respiratory infections, and help the body clear sinuses.

Care must be taken, however, not to introduce infection with contaminated irritant or unclean devices.

There have been recent reports of Primary Amebic Meningoencephalitis (PAM) caused by the use of neti pots.

PAM is caused by an amoeba named Naegleria fowleri. This amoeba is found throughout the USA, but is more prevalent in warm fresh water. It can also be found in hot springs.

The amoeba enters the body through the nose and is able to travel through the nasal passages to the brain where it can cause an infection.

PAM is a rare infection and there have been only 123 cases reported in the USA since its discovery in the 1960s. That being said, the disease is almost uniformly fatal with only two known survivors.

Most cases of PAM occur in young boys who have been swimming in fresh water. Recently there was a cluster of cases in Louisiana in neti pot users, and the amoeba was found in the tap water.

The CDC recommends using distilled water as a base for the irrigation solution, filtering the water through a 1 micron filter, or boiling the water prior to use. Water should be boiled for at least three minutes.

Commercially available sterile saline mists and spray are also readily available at drug and grocery stores.

Neti pots should be cleaned regularly and the CDC recommends using ones that are dishwasher safe.

One could hypothesize that others pathogens could be introduced into the body via this route, and nasal irrigation should be performed in a careful and sanitary fashion. No one wants to get sick while trying to prevent illness!
