Here is an interesting article on Amitriptyline withdrawal that I find helpful. I am helping a patient lower this medication and am surprised at how severe the withdrawal symptoms can be. The patient stopped taking Amitriptyline 5 mg abruptly, along with diazepam 2 mg, after taking it for two months. The withdrawal symptoms consisted of severe insomnia, anxiety, burning sensations, and depression. She had to restart her medications, this time her psychiatrist put her on Amitriptyline 25 mg and Escitalopram 5 mg.
It is possible to support the withdrawal process through both functional and energy medicine approaches, but this is one medication that may require both serotonin (using 5-HTP) as well as catecholamine support (using DL-phenylalanine) in order to come off of it gradually. Do not underestimate the withdrawal problems associated with Amitriptyline!
