This is consistent with my understanding, but:

- how serious are the side effects?

- how well would harmless placebo pills work in their place?

I currently believe that there needs to be a safe, placebo-like option for people without severe illnesses. For those who are severe (and can tolerate side effects as serious as suicidality), it still seems to be a good idea to prescribe them.

>"We excluded quasi-randomised trials and trials that were incomplete or included 20% or more of participants with bipolar disorder, psychotic depression, or treatment-resistant depression." Wikipedia defines treatment resistant depression as "cases of major depressive disorder that do not respond adequately to appropriate courses of at least two antidepressants." Maybe I'm unfamiliar with study methodology, but does…

SSRIs are generally indicated for what's called mild/moderate depression, the most common form, not for the serious conditions that you highlighted. There were some older meta-studies that called into question their general efficacy vs. placebo even for mild/moderate depression but this new meta-study (with the additional previously unpublished data from their initial approval trials) looks like it has finally settle…

I am obviously confused, as usual. I'm not used to reading these studies.

I'm looking at the study. I'm looking at the #3 graph under Tables and Functions Tab.

It says amitriptyline is the best drug? Isn't that an older drug, or am I misreading the chart?

Reading through the paper it seems like all the statistics are presented as Odds Raios vs placebo. But I couldn't find the actual efficacy of placebo. Did I miss it or does someone know?

Something being twice as effective as a placebo is great when the placebo effect helps 30% of patients, not so much when it's 3%

I think that the United States is getting better about dealing with mental health, but we still have a long way to go. This is a little soap-boxy and anecdotal, and I apologize if it's inappropriate here. If I hadn't gotten a prescription for Prozac I probably would have killed myself by now. And I definitely would have destroyed my marriage and most of my important friendships. That's not an over-dramatization, it's…

As someone in the very same boat, I appreciate and can relate to the line you have to walk. My life was positively changed by going on Prozac in a way that I didn't think was possible. After years and years of trying any way of dealing with depression that didn't involve medication, I was absolutely at a dangerous place. Most of my reasoning was that I didn't really believe in the efficiency of medication, and even if so, I didn't think I was actually someone with depression, just that I had been, since i was a kid, putting myself into constant situations that caused severe anxiety and depression. It didn't all work at once, and I had a lot of weird steps between starting and being in a state that I would now consider "my normal self that I never knew I actually was", but it's been an overall life changing experience.

That being said, I understand that medication, or even the same medications, can't work for some people in the way they did with me. It's difficult to explain the position of "I know medication doesn't always work and isn't always an answer, but sometimes it is an answer that I would hate to be missed out on".

As another person who is on antidepressants, and tried going off them for a while: well, duh. Yeah, I know, anecdotes aren't data, and I'm glad this is being verified by more reliable statistical methods, but this is not news to the many of us who might be dead or worse if someone hadn't said "you are sick--go see a doctor" and if that doctor hadn't said "you need medication--let's see if this works".

Without antidepressants, my best case scenario is being an unemployed grad-school drop-out. With anti-depressants... well, it's amazing what you can do when you actually have enough neurotransmitters in your brain!

This notion of chemical imbalance in the brain is wrong/misleading by the way.[0]

PSA: The first thing to realize is that psychiatrists, and regular practitioners, have no clue what will work for you.

In my case, it took 8+ years of trying, giving up, and trying again. E.g., Prozac didn't affect me at all, but the doctor never suggested increasing the initial dose. Paxil didn't work, Lexapro kinda worked, and now on the maximum dose of Effexor.

The biggest difference makers were the doctors perfectly willing to help me find a solution. Keep trying to find one like this, and don't give up.

This applies to everything in life. Just because an expert tells you it'll work, doesn't mean it will. Balance the possible negative effects against the possible gains, and once you have learned how it affects yourself, make your own decision.

(Unless trying something creates a condition that cannot be reverted, e.g. death)

So it should probably be noted that given these are powerful psychotropic drugs so it's difficult to control for them with a placebo and we don't really know their longitudinal effects. Also proper diet, exercise, yoga, or meditation can all help with mood and depression but you can't patent that shit. This isn't to say the drugs have no value but the bar to use them should be high.

The problem with studies of antidepressants is that they're almost all based on short-term, fixed-length treatment courses. After all, you can't do a double blind trial that lasts years on end; it would be unethical to give someone a placebo for that long, when antidepressants are believed to work better. Yet (AFAIK) people who go on antidepressants typically stay on them for years, so the studies are reviewing a fairly artificial use case. It's like the handful of controlled trials that attempt to compare programming languages, which by necessity ask participants to solve short, fixed programming exercises, even though that bears little resemblance to the process of real software development.

In the case of antidepressants - on one hand, there are some reasons to expect short-term interventions to be the best-case scenario in terms of evaluating benefit, such as the greater risk of side effects with long-term use, and drug tolerance effects. On the other hand, I suspect (but don't have data to prove) that placebos are much less effective in the long term. People think the placebo effect is in part a reaction to the social experience of interacting with a doctor, getting personal attention and concern for whatever condition is supposedly being treated. To the extent this is true, the novelty of the experience is probably a large factor, and over the long term you'd expect a reversion to the mean. So even if antidepressants are less effective in the long term than the short term, they might be more compelling as a treatment option, because the alternative (placebo) loses even more of its effectiveness.

Edit: Another factor is that the effects of reduced depression may take a long time to be fully apparent. Depression tends to work in feedback loops: as an oversimplified example, you feel bad about yourself, so you lose motivation to take care of your life, so you start neglecting essential tasks, the consequences of which make you feel even worse about yourself. And lifting yourself out of depression is the same thing in reverse. So if an antidepressant has the effect of reducing your susceptibility to depression - i.e. under the same life circumstances, you wouldn't lose quite as much motivation, or see things quite as darkly - then even a small change might tip the balance and let you stay at equilibrium in a more functional state of mind. But before you can reach that equilibrium, you have to go through a long process of getting your life back in order and regaining self-confidence.
