1 doctor agrees

In brief: Not many

Any eye drop can have side effects, although patenol is usually very well tolerated.
Some expected side effects might be stinging or burning feeling when used, possible mildly blurred vision, redness of the eyes after use. These are all fairly rare with patenol, in my experience.
