All you need to know about neti pot safety

Neti Pot Safety

Occasionally, a doctor may recommend using a neti pot to help with allergies, sinus infections or congestion. A neti pot is a small tea-pot shaped vessel you can use to pour liquid in one nostril and out of the other. However, you need to be careful with how you use it, or, more specifically, what you put in it.

A December 2018 article in USA Today discusses the case of a 69-year-old woman who died after getting infected with a brain-eating parasite following a year of use with a neti pot. The problem wasn’t that she used a neti pot, however. It was the tap water.

The Centers for Disease Control and Prevention notes untreated tap water is not safe to use because it can contain parasites, such as Naegleria fowleri, the brain-eating amoeba. So, you may be thinking, if it’s not safe for use in neti pots, does that mean it’s not safe to drink? Not to worry, even if one of these nasty parasites is in a big sip of water, they won’t survive stomach acids.

If a doctor recommends using a neti pot, follow the directions closely to make sure you stay safe. Remember, the CDC recommends using water that has been boiled for 1 minute (3 minutes at elevations above 6,500 feet) and cooled, or using distilled or sterile water.

If none of these options is available, the CDC says you can use filtered water, but you should be sure the filter’s label reads NSF 53 or NSF 58. The label may also say “absolute pore size of 1 micron or smaller.”

Naegleria fowleri infections

Why is it so important to use properly treated water? Because amoebas like Naegleria fowleri could enter the body and lead to a disease known as primary amebic meningoencephalitis or PAM. 

The CDC explains symptoms usually appear 1 to 9 days after infection, and early symptoms of PAM are similar to bacterial meningitis. They include:

  • Headache
  • Fever
  • Nausea
  • Vomiting 

The CDC says symptoms that set in later can include:

  • Stiff neck
  • Confusion
  • Lack of attention to people and surroundings
  • Loss of balance
  • Seizures
  • Hallucinations 

While infections from Naegleria fowleri are rare, when they do occur, they are usually fatal. In fact, the CDC notes only 4 known people have survived from the infection of the 143 infected between 1962 and 2017. It’s a fatality rate of 97%.

Infections from the amoeba tend to happen in the summer months—July, August and September. The CDC says this is because the amoeba grows better in warmer water.

If your doctor recommends a neti pot, talk with them about safely using it and ensure you take the necessary precautions with the water that you use.
