Nasal sprays expire for several important reasons. First, the active ingredients break down over time. This means they may not relieve congestion or allergies effectively.

Second, contamination becomes a concern. Every time you use the spray, bacteria can enter the nozzle. Over time, this can lead to bacterial growth inside the bottle.
