The first thing i would look at is why that particular eye drop was prescribed.
Are there alternatives? Are there downsides to the particular drug?
Be VERY careful of expensive patent medicines.
One reason for expense is we live in a country with the MOST lawyers in the world.
Unlike mexico, there is not a lawyer behind every bush waiting to sue manufacturers.
I’ve been using Restasis for at least 10 years. It’s very expensive so when the generic came out, I was thrilled. There are a few other alternatives, but they are equally as expensive.
It’s prescribed for extremely dry eyes that no other medication will help.
No side effects for me and it works.
