Saline Solution for Pink Eye (Conjunctivitis): Use and Benefits

Sterile saline (0.9% NaCl) is a safe, first-line supportive measure for conjunctivitis.

Benefits

• Mechanical cleansing: flushes allergens, debris, discharge, pathogens.
• Reduces inflammation via osmotic effect.
• Soothes irritation.
• Maintains moist environment for healing.

Proper Use

1. Wash hands thoroughly.
2. Use fresh, sterile single-use container.
3. Instill 1–2 drops in affected eye(s), 3–4× daily.
4. Blink to distribute.

Important

• Saline treats symptoms only—not the underlying cause (viral, bacterial, allergic).
• Discontinue if worsening; see eye doctor.
• Also useful for contact lens rinsing and pre/post medication irrigation.

Never share eye drop containers.
