Common Questions About Nasal Spray Saline Safety

UNSAFE

Is it safe to use nasal spray saline after the expiration date?

Expired nasal spray saline may have reduced potency and effectiveness. The FDA does not recommend using medications past their expiration date, as the chemical composition may change over time. Some medications can become less effective or potentially harmful. Consult a pharmacist before using any expired medication.

CAUTION

What if nasal spray saline looks different than when purchased?

Changes in color, consistency, or separation in nasal spray saline typically indicate the product has degraded. While this may not pose a safety hazard for non-food items, it usually means reduced effectiveness. If the product has solidified, separated significantly, or changed color dramatically, it is best to replace it.
