Prednisolone
"After completing 4 weeks of treatment, as prescribed, my eye became irritated i.e pain/discomfort,  redness and sensitivity to light. I  was told to repeat it for 4 more weeks. I've been on it now for 4 months with the same results. Stop it, and soon eye irritation begins again. And I'm back to using it again. Doesn't seem right, especially when one should not use it for long periods Doesn't seem to be working.
I too agree that it stings when instilled and I also taste it."
