I will just say briefly...I have dispensed amitriptyline for 40yrs+ and never had patient questions or complaints like those that appear on askapatient.

I've viewed that site, and I would caution people to read it with care. I've seen such trollish behavior I cannot believe over there.

Some comments seem legit, but others, appear to be fabricated for fun or mischief IMO.

A much better balance can be found here: Official FDA medwatch reports from healthcare professionals:

type in amitriptyline in the search and reports will come up.

For what it is worth I took a TCA over a decade ago for just over a year for a severe case of sciatica. I used doxepin in low dose for the pain so I could continue working. I took 20mg at bedtime (two 10mg caps). I didn't notice any major problems at all this low dose. It worked well, and my sciatica finally healed up and resolved.
