Though this article concentrates on the SSRIs, other meds like the SNRIs can have a similar or even worse withdrawal effect. We didn't call it "Side Effexor" for nothing.

People legitimately need these drugs, including in the short term. The problem for acute stressors once they resolve is how to get them back off.

Paracompact•59m ago
> Though this article concentrates on the SSRIs, other meds like the SNRIs can have a similar or even worse withdrawal effect.

And don't even get me started on tricyclics or MAOIs... no, seriously, don't get me started on them! The current generation of first-line antidepressants (SSRIs/SNRIs) might as well be free compared to the old school crazy pills.

SV_BubbleTime•24m ago
> school crazy

Yep, that’s how I associate SSRIs.

D-Machine•1h ago
Best way to manage the withdrawal would be to dramatically reduce them being prescribed in the first place.

The linked article says they have "small to moderate effectiveness", but this is being far too generous. The correct way to measure drug effectiveness is if the treatment meets the standard of a minimal important difference. I.e. you measure depression on various rating scales, like the 17-point HAM-D, and research suggests a minimal important difference (i.e. one patients and clinicians can actually notice) needs to be about 3-5 points. But the average effects of almost all antidepressants do not meet these thresholds, i.e. the effect actually appears practically invisible. [1]

Then you'll get waffling like "oh, but it really has a big effect for some people", but, well, no, we've looked at that too, and the placebo groups get just as miraculous "big effects", i.e. evidence supporting the idea "they really help some people" is also largely lacking [2-3]. All the other attempted saves ("oh, but eventually you find one that works for you") are also not really well supported either [4].

Like, maybe they really help some people, but it is far, far less clear than most assume, and should be balanced with concerns like withdrawal and serious side effects like emotional blunting and sexual dysfunction.

EDIT: And just to be clear to anyone doing a drive-by downvote thinking this is about recent asinine US politics, it emphatically isn't. There are serious methodological concerns here that desperately need to be communicated to the public.

On an academic level, we have reined in much of the excess enthusiasm in antidepressants that was courtesy of 90s-era pharmaceutical reps and ad men, but I don't think this revision ever occurred in the cultural consciousness at large.
sandcat_•54m ago
To provide one additional anecdote: I came off escitalopram with no taper after taking it for about five years (10mg). I got brain zaps for a while, got very irritated at times, but largely was fine after a few weeks. Not downplaying the withdrawal effects for some people, but they’re not as catastrophic as this article suggests for many (perhaps most).

And overall I’m very glad I took it! It got me through a rough patch, and seems (in combination with therapy, and some life changes) to have rewired me a little. Symptoms I had for a decade prior have not returned. And I’m not sure I could have made those life changes without it.

Sadly my arachnophobia came back though. Oh well.

delichon•40m ago
Good news, exposure therapy is quite effective for arachnophobia and is the first-line treatment. SSRIs do not have the same level of supporting evidence, and the effects are not as durable.
sandcat_•32m ago
Thanks, yeah, but if I’m honest I don’t really care enough to go through with it. I almost did once, years ago, the London Zoo have a programme.

I mentioned it though as one of the most stark changes I noticed after getting on an SSRI was pretty much immediately losing my fear of spiders. It was the first sign I had that showed it was doing something.

I used to literally, on occasion, launch my phone across the room if I was scrolling and came across a spider (sometimes drenching myself with coffee or whatever in the process!) and then one day, shortly after getting on it, I stumbled across some awful tarantula video or something and I just stared at it like “huh, why am I not freaking out”.

bsuvc•37m ago
It's been years since, but I too had brain zaps coming off of it. It took a few months for those to go away.

I tried to describe it to my doctor and he seemed like he never heard of it before and sort of look at me like I was crazy, or at least that is what I sensed. But I ended up researching online and found it was a thing that happens.

SV_BubbleTime•25m ago
I find it funny that no one else on this forum is shocked that every time anti-depressants and ADHD medications come that the sheer number of users who have first hand experience is far too high for a social good.
wredcoll•16m ago
Wait til you hear about microplastics!
majormajor•10m ago
Most of us have no idea how many non-commenting readers w/o first-hand experience are just reading, and so no ability to draw any conclusions about the number of ones who comment with first-hand experience. 100 people out of a 1000, and 100 people out of a million, are very different things.
pibaker•9m ago
An HN post like this will gather like what, at most two dozens of anecdotes from a highly self selected user pool of maybe a million top? Is this how you base your "sheer number" on? Is this how you judge what is good or bad for your definition of social good?

I got some other news for you, buddy. https://news.ycombinator.com/item?id=49444514

Not sure what you're basing this on -- hopefully not just your impression after reading things online.

laughing_man•6m ago
SSRIs and SNRIs just didn't work very well for me. If they had an positive effect at all, it wasn't enough to rise above the proverbial noise.

Coming off of them wasn't too bad though. I got the brain zaps, but those were easy to cope with.

More than anything the whole experience was a waste of money, and what finally fixed my problems was retirement and a greater attention to my health.

D-Machine•52m ago
Yup, I would agree. The meta-research / methodological research and awareness here is really quite impressive, even though its conclusions are a bit grim and not well-known.
jakebol•19m ago
A good book on this is Mind Fixers: Psychiatry's Troubled Search for the Biology of Mental Illness. Describing the history of how many of these classes of drugs came about is pretty eye opening, I would say the book is pretty nuanced in its conclusions.

Have we reigned in the number of perscriptions?

Because the 1 in 10 stat I find seems a bit low, at least in my circle, and those are the ones who are open about it.

And the people I know have been on them approximately a decade. What baffles me is that a fair number of them triggered their own depressive episodes, and likely did need therapy and something at the time - but have all long since move past those "moments".

D-Machine•39m ago
I am not sure, but recommendations to prescribe in mild cases have quietly been reigned in a bit by e.g. NICE https://www.nice.org.uk/guidance/ng222/chapter/Recommendatio....

See also: The Serotonin Theory of Depression: a Systematic Umbrella Review of the Evidence (2022). It's worth reading the introduction and results in full, but here are two important quotes (footnote markers removed):

> Our comprehensive review of the major strands of research on serotonin shows there is no convincing evidence that depression is associated with, or caused by, lower serotonin concentrations or activity. Most studies found no evidence of reduced serotonin activity in people with depression compared to people without, and methods to reduce serotonin availability using tryptophan depletion do not consistently lower mood in volunteers. High quality, well-powered genetic studies effectively exclude an association between genotypes related to the serotonin system and depression, including a proposed interaction with stress.

> The chemical imbalance theory of depression is still put forward by professionals, and the serotonin theory, in particular, has formed the basis of a considerable research effort over the last few decades. The general public widely believes that depression has been convincingly demonstrated to be the result of serotonin or other chemical abnormalities, and this belief shapes how people understand their moods, leading to a pessimistic outlook on the outcome of depression and negative expectancies about the possibility of self-regulation of mood. The idea that depression is the result of a chemical imbalance also influences decisions about whether to take or continue anti-depressant medication and may discourage people from dis-continuing treatment, potentially leading to lifelong dependence on these drugs.

https://www.nature.com/articles/s41380-022-01661-0

zdragnar•29m ago
The conclusions in that were not universally accepted, and some critiques were rather damning:

https://www.kcl.ac.uk/news/a-response-to-the-serotonin-theor...

Personally, I both agree that SSRI antidepressants were likely overprescribed early on, and disagree with the notion that the chemical imbalance theory is unsupported. N = 1, they can absolutely work. It took a few to find one that really did, hence I am certain it is not a placebo effect.

justonceokay•45m ago
So did you take them and have a bad time? Because they definitely work for me and I doubt a placebo could have such a large effect on the 48 hour stomach pains I used to get alongside my frequent panic attacks.

I find it funny that people complain about emotional blunting when that is the entire purpose of the drug. I would prefer not to live on the razors edge ever again. I’ve had chronic anxiety and depression ever since I was a child, though.

D-Machine•41m ago
For some people the emotional blunting is desirable, especially as you said, if the problem is chronic anxiety. But for many other people, their depression is defined by a lack of positive affect and anhedonia, meaning that emotional blunting is literally making things worse.

Depression is highly heterogenous, and I am glad the medication helped you.

JoshTriplett•36m ago
> I find it funny that people complain about emotional blunting when that is the entire purpose of the drug.

The ideal would be to blunt the negatives but not the positives. The effect of some of the older antidepressants can be to blunt both, across the board.

Some of the newer atypical antidepressants can address depression without making everything flat.

jakebol•6m ago
High dosage SSRIs have much more clinical evidence of efficacy for addressing anxiety disorders vs a placebo than depression.
burnte•44m ago
> Best way to manage the withdrawal would be to dramatically reduce them being prescribed in the first place.

No, that will just hurt more people up front for longer. The truth is antidepressants have a larger effect on mental health than actually gets reported because of how improvements are measured. If you look at a patient who doesn't get out of bed, is in trouble at work/school for performance, doesn't spend social time with friends, etc, and 6 months after starting an SSRI they're indistinguishable from other people but still have other issues, we call that a "mild impact" because they self-report other problems.

The truth is we took someone from being passively suicidal to functioning normally, and we fail to look at the self-reported problems, we just report them. The self reported problems tend to change from "I don't care about anything" to "I'm unhappy at my job" or "I'm stressed at how much I have to do with work and my kids and home." These are actually major improvements, the patient has gone from being actually clinically depressed to significant improvement but continued unhappiness with life circumstances as opposed to unhappiness with life in general.

Antidepressants are amazing, we need to improve therapists and how they deal with medicated patients. Too many therapists dismiss meds and too many psychiatrists dismiss therapy. I've been in this space for a long time now, healthcare IT in the mental/behavioral health space. We're engaged in a long erm research study to help demonstrate the value of a tightly integrated therapy/psych team and more advanced treatments and when you get everyone in the room pulling in the same direction patient outcomes are amazing.

One actual issue that antidepressants face is that they're not the only treatment, but many doctors are reluctant to move to TMS or esketamine, despite the amaing success rates they have with patients who have not had success with two or more drugs. If two drugs failed you, the third has a 14% chance of helping. The 4th is single digits. But you pivot to TMS and you see 60-80 percent improvement rates. Esketamine is close too.

ADs aren't the problem, it's that we don't take mental health as serious as we take physical health.

D-Machine•36m ago
> The truth is antidepressants have a larger effect on mental health than actually gets reported because of how improvements are measured.

The truth is actually exactly the opposite, and I provided very high-quality evidence demonstrating this to be the case. You have nothing but bald assertions.

tredre3•19m ago
> But you pivot to TMS and you see 60-80 percent improvement rates. Esketamine is close too.

I have received both rTMS and esketamine and the providers themselves told me they saw roughly a 30-40% response rate (not remission, that's even lower!). Upon researching the topic myself, I found that the meta analysis usually agreed with this 30% figure, but recent research papers mark eskatamine even lower. Both treatments can be miraculous for a few select people and it makes a good headline, but it's a total failure for the majority of people.

I agree with you that those treatments should be easier to access, though.

> Too many therapists dismiss meds and too many psychiatrists dismiss therapy.

This is the only factually true statement in your entire comment.

googaar•30m ago
I can’t believe we’ve normalized anti depressants as a society.

I’m about to get downvoted into oblivion for this take though.

I’m not trying to discount mental health, I just think there are better solutions than drugs to fix your state of mind.

Also think that some people are dealt a tougher hand than most, and that for a small subset of humans, anti depressants are the most fitting cure.

D-Machine•27m ago
Agreed. They have to be significantly helping at least some, but we can't say who these people are for certain yet, or how many there really are.

And yes, in some cases, no other options are possible, so even if the evidence is pretty dismal for their effectiveness, they are still broadly safe enough to definitely be worth a try. They probably just shouldn't be the first-line approach.

SV_BubbleTime•20m ago
> I’m about to get downvoted into oblivion for this take though.

But look at by whom. It’s kind of like gut bacteria making you tolerant to yeasts that they want. MAYBE… the brain altering medications have something similar to… Let’s say a survival mechanism?

Obviously, just joking. Is far more likely that someone is going to defend the medication they’re on because to admit that have been taking and are now addicted to is something harmful, maybe hard swallow.

Double for parents and doctors. If I’m a parent and my kid is on some ADHD SSRI antidepressant methamphetamine cocktail… and it turns out it’s bad and based on a pharma bro cash money grab, that means I was a bad parent. Try and tell me motherfuckers won’t go to their graves before they admit that they harmed children inadvertently.

wredcoll•9m ago
There's hundreds of years of "depression isn't real and even if it was real the only treatment is to take a walk in the woods!!" and like a decade of "man, ssris are great, they really helped me".

Public responses have probably not finished overcorrecting.

wat10000•11m ago
I don’t get why people are so negative about drugs. They’re just a medical treatment, with pluses and minuses. If they help and they’re not too costly then what’s the big deal? Half the population is addicted to caffeine and nobody cares. A huge number of people need medical intervention for other things and we don’t get this quasi moralistic opposition to them.
D-Machine•3m ago
Agreed. The problem is largely that the pluses of antidepressants have been quite significantly overstated, and the minuses have been understated, meaning the cost-benefit equation is unfortunately quite different than what the general public assumes.

We don't want to get rid of them, we just need to recalibrate prescribing, and also to properly assess cessation at intervals more frequently than we have been.

sheepscreek•8m ago
It can be catastrophic if one is managing family life, kids, taking them to and from activities on top of one’s own work. Then come misc stresses like tax returns, some expensive home repair, etc. Also dealing with depression without the anti-depressant. Switching mental health medication is no fun.

I am glad your experience was tolerable but it’s a whole arc and everyone’s tolerance + circumstances are unique which makes it all the more challenging (even for doctors).

The idea that simple serotonin deficiency is the whole entirety of all depressions is 100% discredited and completely incoherent in the face of current evidence, but yes, for sure it remains clear and plausible that some forms or aspects of depression involve a serotonin deficiency.

However, tianeptine is serotonin reuptake enhancer and also can help with depression, so any simple deficiency hypothesis also doesn't look good either.

Broadly, the "chemical imbalance" theory, left vague and unspecified, is still basically sane (though not specific enough to be super useful).

sneezychl•3m ago
The "chemical imbalance" theory is objectively wrong, but still useful in that it conveys the fact that mental disorders have physical causes. It's a purposeful simplification.
