Frequently asked questions
Should I use drops or ointment?
Both work; ointment blurs vision more and is often used at bedtime or for children. Follow your doctor's advice.
Will it help viral conjunctivitis?
No — antibiotics only work on bacterial infections.
The eye got redder and itchier — why?
This can be an allergy to the drop. Stop and see your doctor.
