Sorry your daughter's going through this- it's shit, it really is!
I was 17 when I started on citalopram and just past 19 when I started prozac, and still 19 when I started taking the max dose. Am 20 in a couple of months now and no signs of going off it, but this dose and drug are right for me even though things have improved.
IME it's been worth it, but it's not a miracle fix. At the moment I'm feeling 10x better than I did 2 years ago. But I'm dependent on the drug. If I miss a couple of days, I'm a weepy mess. And when I weaned off one AD and started on the other, the week in between was horrible. Don't know if that's just me in my natural depressed state or the fact that I'm messing around with my brain chemistry or whatever.
To 'lift her mood'- well, I would resent him saying that. He shouldn't be starting her off with any expectations. It's almost a gamble in a way- not saying that if she doesn't gain, she'll necessarily lose- but you don't know what will happen. Sometimes a 15mg dose will work wonders for someone, and sometimes a 60mg dose of something else will do nothing for them, apart from making them feel awful through side effects. It really is an adjusting game, if you decide to go down that route. And if she's expecting an improvement and instead starts to feel very empty, flat and numb, she may not be able to cope with that. The first sign of my depression came at 15 when I began to feel incredibly numb (without drugs) and I couldn't cope with the idea and spiralled down quite quickly, I was very unhappy with the idea that I'd 'lost my emotions'. It was very scary and I imagine it would have been even worse if someone had promised me that things would get better and then they got worse in an unexpected way.
My parents were very against my taking them, even though they knew that I wasn't doing well, but they know a lot of people who are on these meds- depression and anxiety related disorders run way back in our family on both sides and now they recognise that it was a good step to take. The NHS has been a bit crap really- they'll shove pills at you as soon as you prove that you're not functioning well, but when it comes to really trying to get at the root of what's causing your problems, they have this completely insufficient network in place and it's so easy to fall through the gaps. So my parents were frustrated by that as well.
Good luck to your DD- and remember that you can always refuse the pills if the CAHMS people insist. You can go away and do research and if you feel uncomfortable, you can ask him a lot of questions. They are there to help your DD so if you have to make a pain of yourself so be it.
What does she think? Does she have anything against taking them, or would she want to take them?
I could go on, but don't want to write an essay!
