Always rinse your nasal passages with NeilMed® SINUS RINSE™ packets only. Our packets contain a mixture of USP grade sodium chloride and sodium bicarbonate. These ingredients are of the purest quality available to make the dry powder mixture.
 
Rinsing your nasal passages with only plain water without our mixture will result in a severe burning sensation as the plain water is not physiologic for your nasal lining, even if it is appropriate for drinking.
 
Additionally, for your safety, do not use tap or faucet water for dissolving the mixture unless it has been previously boiled for five minutes or more as boiling sterilizes the water.
