Hello and thank you for asking on HCM!
I read carefully your concern.
Feliz is an antidepressant that usually is used for some months to treat depression
, panic attacks, anxiety
, chronic pain
At least a six months period is suggested for the treatment of depression.
If it was recommended for the pain it may be used for a couple of months. You should consult with your treating physician how long to use it.
Hope the information will help.
