Italian researchers have reported in the International Archives of Allergy and Immunology in Sept 2009 that saline nasal rinsing is a safe and effective treatment option for nasal problems in pregnant women with seasonal allergic rhinitis. In their paper titled "Nasal Lavage in Pregnant Women with Seasonal Allergic Rhinitis: A Randomized Study," the researchers instructed the study group to perform hypertonic saline lavages to the nose 3X per day. Of note, HYPERTONIC saline solution was used instead of the more usual isotonic saline solution.
A statistically significant improvement in rhinitis symptoms (rhinorrea, obstruction, nasal itching and sneezing) was found during the observed weeks 2-6. Furthermore, the mean number of daily antihistamines use per patient per week was significantly reduced at weeks 2, 3 and 6. No adverse effect was reported in the active group.

In our office, we recommend the Neilmed Sinus Rinse bottle as the cheapest and most effective way to perform nasal irrigations. Of note, the Neilmed sinus rinse bottle also comes with hypertonic saline version (along with the more common isotonic version). For convenience, irrigation devices (shown below) are also sold, but much more expensive.
