What are the risks of doing nasal washes and sinus irrigation?

Performing a nasal wash or sinus irrigation is generally considered safe. Pregnant or breastfeeding women or those with a scheduled nasal or sinus surgery may want to discuss doing a nasal wash with a doctor beforehand. Some people report getting frequent nosebleeds after performing sinus irrigation. Not using the proper salt-to-water ratio during a nasal wash may result in undue irritation. If the neti pot or syringe you use for the irrigation becomes contaminated, you may put yourself at risk for a sinus infection. It is important to breathe through your mouth during a nasal wash or you may put yourself at risk for inhaling the salt water accidentally.
