Yes, medical-grade saline solution is sterile until opened. It is manufactured and sealed to be free from microorganisms for safe use in medical and home care applications.
Once opened, sterility can no longer be guaranteed, which is why many saline products are designed for single use. Always follow product labeling regarding storage and disposal to help maintain safety and reduce contamination risk.
