Are Neti Pots Safe?

Neti pots may seem like a simple way to deal with clogged sinuses, but there are some things you need to know before you use them. Here, experts from the federal Food and Drug Administration (FDA) share advice:

Little teapots with long spouts have become a fixture in many homes to flush out clogged nasal passages and help people breathe easier.

Along with other nasal irrigation systems, these devices — commonly called neti pots — use a saline, or saltwater, solution to treat congested sinuses, colds and allergies. They’re also used to moisten nasal passages exposed to dry indoor air. But be careful. According to the FDA, improper use of these neti pots and other nasal rinsing devices can increase your risk of infection.

These nasal rinse devices — which include bulb syringes, squeeze bottles, and battery-operated pulsed water devices — are usually safe and effective products when used and cleaned properly, says Eric A. Mann, MD, PhD, a doctor at FDA.

What does safe use mean? First, rinse only with distilled, sterile or previously boiled water.

Tap water isn’t safe for use as a nasal rinse because it’s not adequately filtered or treated. Some tap water contains low levels of organisms — such as bacteria and protozoa, including amoebas — that may be safe to swallow because stomach acid kills them. But in your nose, these organisms can stay alive in nasal passages and cause potentially serious infections. They can even be fatal in some rare cases, according to the Centers for Disease Control and Prevention (CDC).

What Types of Water Are Safe to Use?

Distilled or sterile water, which you can buy in stores. The label will state “distilled” or “sterile.”

Boiled and cooled tap water — boiled for 3 to 5 minutes, then cooled until it is lukewarm. Previously boiled water can be stored in a clean, closed container for use within 24 hours.

Water passed through a filter designed to trap potentially infectious organisms. The CDC has information on selecting these filters.

Make sure you follow instructions.

“There are various ways to deliver saline to the nose. Nasal spray bottles deliver a fine mist and might be useful for moisturizing dry nasal passages. But irrigation devices are better at flushing the nose and clearing out mucus, allergens and bacteria,” Mann says.

Information included with the irrigation device might give more specific instructions about its use and care. These devices all work in basically the same way:

Leaning over a sink, tilt your head sideways with your forehead and chin roughly level to avoid liquid flowing into your mouth.

Breathing through your open mouth, insert the spout of the saline-filled container into your upper nostril so that the liquid drains through the lower nostril.

Clear your nostrils. Then repeat the procedure, tilting your head sideways, on the other side.
