David Taylor says this about the NEJM study: "This study shows that discontinuing antidepressants in long term users leads to a greater risk of relapse than that seen in people continuing their medication. It seems to suggest that antidepressants are effective at (1/n)
preventing relapse. However, the speed and nature of antidepressant discontinuation is known to have a major effect on risk of relapse and this alone might explain the differences observed ..2/n
- patients were withdrawn over two months using a coarse linear dose reduction schedule which included alternate day dosing (even with short-acting drugs). ..3/n
It is also possible that the use of antidepressants itself sensitises people to future episodes of depression. 4/n
The overall conclusion is that people taking antidepressants for more than two years and who are well have a >50% chance of relapse if the antidepressant is withdrawn over two months using alternate day dosing. 5/n
Longer, hyperbolic and more individualised withdrawal regimens might reduce the risk of relapse." 6/n

Startling lack of interest in confounding by withdrawal symptoms in this antidepressant discontinuation study in NEJM: bit.ly/3AYzP2Z Withdrawal symptoms in this discontinued group render this study uninterpretable. (1/n)
Withdrawal symptoms in the discontinuation group would have inflated the apparent rate of relapse in this group (2/n)
Patients on ADs for at least 9 months were taken off by halving for a month and then halving further for a month before stopping. Much quicker than the ‘months or longer’ recommended by RCPsych guidance and much faster than most patients can tolerate.bit.ly/39QwOpB (3/n)

Enjoyed the @rcpsych IC session on deprescribing with @wendyburn David Taylor and Robin Murray. We had over 100 questions put to us - not seen so many before. Some very good questions from psychiatrists: 'Why is not a requirement of licensing these drugs that they are shown...1/n
to be safe to stop?'. 'Shouldn't we demand that manufacturers make medications in ways that make it easy to stop?' 'Why have academic psychopharmacologists, who should know best about this issue, both ignored and then minimised this problem?' 2/n
'Should we include a discussion about potential withdrawal phenomena when we are consenting something to start treatment?' 'Is there specific guidance for CAMHS/older age people?' 3/n

Outline of the Cochrane study a bit for those scared of its length. Metro article: bit.ly/3tVfOah Lead author: the dauntless Ellen van Leuween. Co-author @tony_kendrick bit.ly/32KLJhj While there are hundreds of studies looking at starting antidepressants(1/n)
we found only 33 studies looking at stopping antidepressants, a therefore hugely neglected area 2/n
Most studies stopping antidepressants abruptly or in less than 4 weeks. This is not consistent with even the current lacklustre NICE guidance (stop over more than 4 weeks) and certainly nothing like the improved guidance from RCPsych bit.ly/3dHYUpL (3/n)

(Thread) Today we have published a paper on a way to reduce antipsychotics to minimise withdrawal effects and possibly relapse in @SchizBulletin. bit.ly/31bc8Eg with thanks to co-authors Robin Murray, David Taylor, @sameerjauhar and Sridhar Natesan. (1/n)
It extends our work on risperidone to more antipsychotic drugs bit.ly/3tMFdSV
It provides some examples of pharmacologically rational tapering regimes for haloperidol, risperidone, olanzapine, clozapine, quetiapine and amisulpride which takes into account 2/n
their pharmacological characteristics and clinical trials. We suggest reducing dose by 5 or 10 percentage points of D2 occupancy (equivalent to about one quarter or one half of the dose) every 3-6 months. (3/n)

(Thread) With due respect to others who have contributed to my special edition I consider this one of the most important pieces. bit.ly/2OAa1aH @Altostrata When I was coming off an antidepressant and in dire straits, I could not find any guidance on what was (1/n)
going on or how to navigate out of it from published literature. Without Adele Framer I would not have been able to get off my drugs; indeed I am not sure I would be alive. I have learnt a lot from her and now I am very glad that now other clinicians, patients (2/n)
and researchers will be able to learn from the wisdom she has gained over 15 years and deep study. She tells me she looked and looked for an expert to be able to help her and could not find one. Instead, she was forced to become one herself. (3/n)

If you have been tapered off a psych drug too fast by a doctor, is it possible (after recovering) to go back and try to let them know what happened? Understand there may be a lot of anger. But could help others avoid the same fate. Terrible thing to have ask ppl to do I know
I ask this because in a focus group yesterday some ppl had done this. Know this takes a lot of energy. But ppl need to stop being told 'I have never seen this before', 'I don't know what to do'. At some point I am sure @rcgp will spring into action
It is also a numbers game. There are about 30,000 GPs in England. Based on this paper there are 10,000 English people just on a handful of facebook sites who know how to taper antidepressants. There are more ppl learning all the time bit.ly/3qhgTXb
