OMG this is so disgusting that they get people addicted to drugs by shoving them onto people like smarties, and then when you are addicted, they pull the rug from beneath you! See also HRT, and disability benefits. Put people on them, let them live happily on them, then decide it's not do-able anymore, and not cost effective, and take them away and make people go without them.
Makes me SOOOO angry! 
See the head of the Medical Practice if you need to @Kitcat47 Don't be fobbed off. You will come off sertaline when YOU are ready. Maybe that will be never.
Would they take asthma meds, diabetes meds, or epilepsy meds off people? NO. So why they think it's OK to take ant-D tabs off people just baffles me!
Although.......... They have tried to fob me off in the past with a cheap and nasty version of my seretide (purple) inhaler. I asked why and they said because this one is cheaper... and it saves the NHS money. For context, I had suffered from asthma for about 10 years, and it was getting quite bad. I was using a ventolin (blue) inhaler a month, and I'd had several asthma attacks. So around 2012 the doc put me on seretide.
Within 6 months, I felt like I didn't have asthma anymore; it was magical! From then on, a blue inhaler lasted me 5-6 months.
Fast forward to 2017, and the new practice nurse put me on this new cheaper alternative. It only costs £7, compared to the other one that costs £22. I said 'well is it any good though?' She said 'of course it is.'
I had my doubts, and I thought 'how can it possibly be as good?'
It wasn't. Within a few months I was using a blue inhaler a month again.
So I went to the senior doctor and told him I was upset and angry at being fobbed off with clearly inferior meds, and this was my life they were messing with. He apologised and changed it back.
