Hi. My 9 year old grand-daughter has an eye infection ,red swollen watery painful. Both eyes. She is also suffering with a running nose,ear ache. Taken to doctors 4 times not clearing. It has now gone to her brothers eyes. She is allergic to pennicillen and sulpha. I have an eye drop called ceprolen 3%. It was given to my brother for his eye @ mccords eye clinic. Can I use it for my grand-daughters eyes ?
