Personal experience with tapering SSRis I was on for anxiety and depression after my dad died. As with comments below - taper slowly. Even though not on the medication insert, lots of people get "brain zaps" like tinnitus when you move your head even slowly. Quite disconcerting for those who already have mental health issues. See https://www.health.harvard.edu/diseases-and-conditions/how-to-taper-off-your-antidepressant for advice on tapering.

If I ever needed something then I used St John's Wort with no side effects and equal efficacy for me. I don't need anything now.

Ironically I worked in big pharma at the time and sold the drug which helped me but then was so hard to get off. Sorry Frens - I have learnt so much since then my views are now quite awake.

But you also mention other meds, as per advice below, seek help from a doctor or mental health services as meds often have synergies or interactions and you don't want to stop everything at once as your mum may struggle.

When you say it hasn't done her good, no doubt you know your mum the best, but hard after many years to see what the 'benefits' are from the meds she is currently taking. By that I mean she may feel worse in some ways when coming off meds and for some time after. This hopefully will be balanced by less side effects, being more grounded and level plus clearer thought processes. There is plenty of commentary on the web about the misnomer " selective " when referring to these meds 🙂

Ideally mum needs a stress free period and lots of support when she is coming off meds. Good sleep, diet, exercise all help.

Good luck and I hope your mum feels better soon.
