On side effects, father was put on Epilim. My mother is a former physio who worked a lot in elderly care. It was her who spotted drug induced parkinsonism and his freezing in doorways.

His Epilim was for post stroke epilepsy. The (bleed) stoke was we think caused by streptokinase given for a heart attack he (proven) didn't have (more than likely it was a menniers).

Suspect the medical profession gets far more right than wrong but is not infallible.
