I threw away and replaced all my skincare and makeup, went to the ophthalmologist at least 8 visits; used steroid medicine to clear this up. This drop is horrible and dangerous. I paid $200 out of pocket for it and triple that to be treated to clear side effects. I am so angry I used it again today and burnt my eyes yet again; they look bloody red and swollen! It will take 3-4 days again to feel better. DO NOT USE!"

For Conjunctivitis, Allergic "I used Lastacaft for several weeks. Initially, it stung, but I continued to use it because my doctor recommended it, and I believed it might help my allergies. Lastacaft gave me redness, swollen eyelids, burning itch. Apparently, I am allergic to it. But the reaction did not happen until several weeks of use."
