Immediate Treatment for Pepper Spray Exposure to the Eyes
The immediate treatment for pepper spray exposure to the eyes is to irrigate with copious amounts of tap water for at least 15 minutes to minimize eye damage. 1
First-Line Management
- Begin eye irrigation immediately after exposure to minimize tissue damage 1, 2
- Use large volumes of tap water for irrigation, continuing for at least 15 minutes 1, 3
- Assist patients in keeping their eyelids open during irrigation as they may have difficulty doing so due to pain and irritation 1
- Avoid contaminating the unaffected eye, other individuals, or surrounding areas during treatment 1, 2
Alternative Irrigation Solutions
- If tap water is not available, normal saline or another commercially available eye irrigation solution may be used 3, 1
- Commercial eye irrigation solutions or balanced salt solutions may be more comfortable and potentially result in less severe eye injury 1
- Ringer's lactate solution is also an acceptable alternative if immediately available 2
Additional Management Steps
- Contact regional poison centers or seek medical help for expert advice on management, especially for severe cases 3, 1
- After initial irrigation, patients may require further evaluation by an ophthalmologist for assessment and additional treatment 4
- Continue irrigation until a healthcare professional determines that the pH of the eye has returned to normal 2
Potential Complications and Considerations
- Despite immediate irrigation, pepper spray can cause significant corneal and conjunctival damage in some cases 5
- Potential complications include epithelial defects, reduced corneal sensitivity, and in severe cases, stromal scarring 5
- Pepper spray exposure may decrease aqueous tear production, which can lead to dry eye symptoms 6
- Some commercial pepper sprays contain toxic carriers (like trichloroethylene or dichloromethane) that may cause more severe and long-lasting corneal erosion 7
Common Pitfalls to Avoid
- Delaying irrigation - immediate decontamination is critical to minimize tissue damage 1, 2
- Cross-contaminating the unaffected eye during treatment 1, 2
- Stopping irrigation too soon - continue for the full 15 minutes even if symptoms appear to improve 3, 1
- Failing to seek professional medical evaluation after initial first aid, especially if symptoms persist 4
