Good! Maybe this Psychiatrist will actually get hold of some quality psychotherapy for you.
You may find tolerance develops, although bar poop out tolerance to anxiolytic/antidepressive effects aren't going to happen. I'll lead with the ones that are least likely to be prescribed due to risk, lack of evidence or just random theory.
I'm sure you know you should be trialing stuff for 14 weeks. Providing you haven't tried the drug I'd suggest you be willing to start with something as simple as an SSRI providing the Psychiatrist assures you he/she is willing use complex polypharmacy as treatment resistance does or doesn't crop up (although I suspect they won't bother). I have recently met a few people who went back to SSRI's (very unhappily) under a new psych having tried a few and a fuck load of other meds with surprising success - what I'm trying to say is that meds can be weird.
Amantadine - NDMA antagonist, MAO-A-I (not sure if reversible or not) and seems to increase release or re-uptake inhibition and a nicotinic alpha-7 antagonist (possible antidepressive effects). There are one or two (I mean 1 or 2) case studies hanging about for OCD and maybe 1 tiny open label for MDD. Side effects unsurprisingly are mainly anxiety/agitation but then again, some people with OCD improve on amfetamine so who knows?
Tramadol - seems to be effective in resistant OCD but addictive, activating and unpleasant for some.
Phenelzine - think you already tried it and you said there was a little response but nothing magical. Know you tried Tranyclpromine. Phenelzine is likely the better bet due to GABA effects. Can combine safely with a mood stabilizer or fairly safely with AAP (I'll be going on about these in a min).
Meclobremide and Clomipramine - risk of serotonin toxidrome(but not severe by any means - reasonably standard) and mild risk of hypertensive crisis. Take it slow and steady and use benzos for any activation at the start.
The serotonergic combo buster: Clomipramine (I think you couldn't tolerate it? if not swap for SNRI if tolerable otherwise SSRI), Lithium, Trazadone (medium to high dose).
The obscene Serotonergic combo buster: Clomipramine, Lithium, Trazadone & Tramadol - Without doubt a risk of Serotonin toxidrome.
Standard treatment resistance combos:
Calafornian rocket fuel (Mirtazapine or Mianserin plus an SNRI) +/- PRN/Buspirone/Pregabalin
SS/NRI/Chlomipramine plus Quetiapine/Aripriazole/Amisulpride/Respidone/Olazepine
SS/NRI/Chlomipramine + Quetiapine/Aripriazole/Amisulpride/Respidone/Olazepine + Pregabalin
You read about antipsychotics side effects and you never want to go on one. You try the wrong one first and you swear never to go on one again.
I think you have tried one or two but If I remeber correctly its one of a few areas that hasn't been well explored for you.
Quetiapine is well evidenced, isn't eactly reknown for having a great (but not awful) side effect profile and can be tried both at low (dopaminergicish) and high doses (antidopinergic) for OCD/anxiety.
Olanzepine will make you gain more weight than you knew possible if you happen to get weight gain as a side effect. Again, it has good evidence and a similar MOA to Quetapine.
Aripiprazole is the only AAP that works as a Dopamine parital agonist at 2 and 3 while being a D4 antagonist. It also is a 5HT1a partial agonist (always good). Think you might have tried this as well and developed terrible akinesia (fairly rare although increase in anxiety is possible). Well I have it on good authority a combo being tried in teriary psychosis clinics and occationally for TRD is a combination of Aripiprazole and another AAP with more sedative qualities with some promising results. This could be a possibility. You could try high/low dose of Aripiprazole and the other AAP both to see what happens.
Low dose Amisulpride is very selective for autoreceptors and a potent antidepressant (plus mild GHB binding effects) (with equal effiacy to amitriptyline). However both low dose and high dose seem to be highly effective (between 200-600 seems ideal with an average of around 350mg). Weight gain is pretty likely as is slight sedation. One study found patients already on an SSRI had a negative response to 400mg (akenthsia) but this may be related to need for down/up-regulation first.
Amisulpride and Aripiprazole is possibly a good choice, if nothing else both would seem to reduce each others side effects. Starting both off at low doses and then increasing one or the other and then both if neither work at lower doses. This is probs the best option I can think of.
Asenapine is an option but I wouldn't be keen until you've tried a few.
Clozepine - this should be the thing you try pretty much just before you decide on major invasive surgey. Of course in combo with a potent serotonergic drug.
Mood stabilizers/antiepeleptics seem to be ones you haven't tried much if at all.
Lamotragine & Carbamazepine seem ineffective but only a few very small trials show this.
Valporate again doesn't seem to do much but may be useful as an agumentation agent or a pre-treatment.
High dose Gabapentin 2400-3600mg may be effective
Pregabalin doesn't have much actual evidence for OCD but clearly reduces anxiety.
Tiagabine at 15mg worked pretty well in one patient on a fuck load of an SSRI
Levetiracetam has a the odd case study supporting its use but thats about it.
Topiramate bar pregabalin may be the most effective (works a little like ruliziole so alone might make you anty).
You could try a combination of up to three seperate antiepeleptics (Topiramate, Tiagabine & Pregabalin or Gabapentin, Topiramate & Pregabalin). Obviously its not something I'd recommend.
An antipsychotic, antidepressant and a mood stabilizer might be worth a go. Or Amisulpride, Aripiprazole and an Topiramate/Pregabalin/Gabapentin (but thats lacking an AD which isn't ideal). You could go for four meds and add in an AD but...talk about fun side effects.
Either way there are still plenty of entirely new combinations. I'd def look into Pregabalin, high dose Gabapentin, Topiramate, Amisulpride, Aripiprazole and a re-trial of Clomipramine.
Antidepressant + antipsychotic + antiepileptic or Antidepressant + antipsychotic x 2 or Antidepressant + antiepileptic x2 can be tried after both AD + antipsychotic and AD + Antiepileptic.
Dear god, I think my brain melted writing that.
