Researchers are evaluating the safety and performance of a decongestant seawater spray pocket valve enriched with essential oils by Gilbert Laboratories. This device is intended for patients aged 12 years and older with acute rhinitis associated with nasal obstruction during infectious episodes like rhinopharyngitis or rhinosinusitis, as well as non-infectious episodes such as allergic rhinitis. The study focuses on assessing results over an 8-day period to understand the spray's effects on nasal obstruction symptoms. The study includes measurement of peak nasal flow before and after the first use of the spray on Day 0, and again on Day 3 for one group of participants. The investigation is designed to monitor the performance of the spray pocket valve and its safety in relieving nasal obstruction due to acute rhinitis. Participants will use the spray as directed, and their nasal airflow will be assessed to evaluate the device's impact. Participants will be monitored throughout the 8-day study period, including completing questionnaires and using the spray according to study instructions. Researchers will measure outcomes such as peak nasal flow from Day 0 to Day 3 to evaluate the device's performance. Safety will also be assessed during this time. The study requires participants to be able to use the spray, complete questionnaires, and attend study visits for evaluations.
