Don't buy it, that list is built from people reporting symptoms whilst on the drug. Of course people with ear trouble have hearing loss symptoms, the very same people who take Amitriptyline to help with symptoms, but that doesn't mean its causing the symptoms. There is no way a neurologist (especially in the UK) would prescribe Ami if they thought it would do you harm. All this is just confirmation bias and unfortunate timing.
This is a similar issue that vexes with MAV - people have migraine as a symptom so some assume its caused by migraine! Barmy! We don't have 24/7 migraines! lol!
