Hi Panda, I was taking a tiny dose of Seroquel for sleep and a dab during the dayfor anxiety. I did well at first, but then after about a week I became very very restless and my anxiety levels really increased. Was this akathisia? I stopped takign the Seroquel Saturday but still have not felt well, what in the world happened?

Hi Chemist, what do you think?
I currently take 12.5 MGs of Lexapro, 15mgs of Buspar, and was also starting to take 7.5 mgs of immediate release adderall (was adderall taking XR before). The reason I went on meds was for anxious depression, OCD, and ADD. things had gotten a bit better (but still had problems with hypervigilance, etc... from anxiety), but then i added in Seroquel. After starting that Seroquel,I did well for about a week, but then I slowly began to notice nighttime agitation and restlessnes... it got worse and worse until I felt like I was back in a high anxiety state. I feel like the cast put on me for my "broken brain" was stripped off and rebroken! I still do not feel well, I stopped taking the Seroquel on Saturday. I'm so upset as I feel like any progress I made went right down the tubes. Maybe it's just me, I think I put alot of hope in the Seroquel for a good night's sleep, and my hopes were dashed, thus sending me into panic mode. Another time this occurred was when I tried to increase my Buspar, I felt so agitated, restless, and panicky that had to drop back down to the lower dose. I've been at this for months and I feel so discouraged, I jsut want a day to come where I peacefully wake up, look around, and say "what a great day!"

HI Chris,
Let's pursue this one. I'm right there with ya and will post a separate question to Chemist. In the meantime, have you tried Ambien for sleep? It's what I'm currently on and find it very helpful. I have fibromyalgia along with bipolar depression and I NEED my sleep and can't take anything that interferes with Stage IV delta sleep. Ambien is great for this and there is absolutely no hangover. It does occasionally poop and I have to take more, but it hasn't been a problem.As with your experience, my recent foray into Seroquel was a nightmare, but a real good clue into what my personal chemistry is doing. It might have something to do with histamines. Keep you posted on anything interesting I dig up. - Barbara

panda, i'm not letting you off the hook so easily, having recently pronounced you the expert. my PDR white-sheet from astrazeneca says ``no appreciable affinity at cholinergic muscarinic and benzodiazepine receptors (IC_{50s} > 5000 nM).'' given an IC_{50} for D_{1} at 1268 nM and IC_{50} of 329 nM for D_{2}, what's an order of magnitude or two among friends? you're still in charge...... :) all the best, chemist

ahhh, the buck has been passed....thank you, panda...remind me not to play poker with you next time i'm down under.....the answer to the post is that, in my opinion, the seroquel dose was too small (i have to read the next one, so don't hold to this just yet) and it sounds like breakthrough anxiety. that said, i still think panda's answer is better than mine in that maybe yes, maybe no (what dose?) and what other drugs are on board that can inhibit/induce/act as substrates for isoenzymes that are also part of the seroquel metabolic route. see, i told you panda's the expert.....on to the next post, where i believe i glimpsed the meds list.....see you there, all the best, chemist

> Hi Chemist, what do you think?
i think panda secretly works for an HMO and is dividing his case load :)
seriously, i am not a fan of buspar: i have taken it, and would choose a lollipop over buspar if given the choice for an effective anxiolytic. my immediate guess is that your body got used to the little dabs of seroquel over the week or so and the buspar was not addressing the *transient* anxiety that can be experienced when titrating up on lexapro (note i wrote *transient*), that the adderall immediate release was a bigger surge of stimulation than you had had before with the extended release, and that you simply were/are overstimulated. in my opinion, the lexapro should slowly be taken to 20 mg - as your comfort level allows - and you should back off on your adderall for a while, or at least take in divided doses until things smooth out, and ditch the buspar. now, we will have you in some quasi-stable state, and sleep will likely need be addressed, as will breakthrough panic and/or daily anxiety. my usual line is, go with klonopin, perhaps 0.5 mg bid. if benzos are not an option, next up is trazadone, a drug i am not particularly fond of, but you can certainly tweak the dose for sleep and for daytime. my stance on trazadone has changed largely to favorable reports from other posters, and i think my experience is the outlier. finally, if you find that trazadone is making you too groggy, go with ambien for sleep and perhaps lower the lexapro for the anxiety. still, i am a fan of the benzos, but this may not be the case for you. please do let us know if this is of any use.....all the best, chemist

Hi Chemist,
Thanks for the information! I've been on Lexapro at 12.5 for about a month or so now, so hopefully the anxiety isn't from that. My PDoc wants me to titrate up to 15 mgs. I'm a fan of the Lexapro because it's supposedly "cleaner" than other SSRIS, though I wish it was one that caused more sedation. I went back to a lower dose of adderall XR at 5mgs. I'm ditching the Buspar and will try Trazodone for sleep (PDOC called it in for me). I've also heard that it has mild anti-anxiety properties, but at this point I'm not keeping my fingers crossed. I just want some darn sleep and to have the agitation/anxiety stop. I was also given some ativan on hand but have had negative experiences with rebound anxiety from xanax so I'm a bit weary of them, plus there's the addiction potential of course.
What do you guys think? Think that I'll be able to actually settle down one of these days? ugh

Must respectfully differ with you, Most Esteemed Chemist, but I don't think it has to do with too small a Seroquel dose and breakthrough anxiety. I had an experience similar to Chris' with Seroquel just last week and a few years back with Zyprexa. Was doing pretty darn good on lithium and pharmaceutical St. John's Wort and decided to go with Seroquel mainly for sleep and any additional benefits an AP might provide for my mixed-states bipolar bane.
Took 12.5mg/night for 4 nights and it was like I woke up on the far side of the Styx after the first dose. Agitated woozy weepy dysphoric clumsy hell. Plus a very uncharacteristic lust/frenzy for anything that hinted of cake or cookie. Kept expecting it to get better but it was getting worse. And I gained 5 lousy pounds for the priviledge.
I realize that 12.5mg is more sedating than higher doses and this dysphoria might have eventually gone away, but the point is that something hit hard and very quickly. A very rapid switch into agitated depression and total relief after stopping. What jumps out at me is histamine. For one, the groggy sedation felt much like an anti-histamine, plus I understand that unbalanced histidine and therefore histamine levels have been implicated in depression. Mainly H3, and Seroquel seems to target H1 but jeez, mere technicalities. Perhaps I'm one of those 'histadelics' (it does feel like hysterical psychedelics for that matter). Perhaps methylation is a factor. I dunno. I only know that something caused this rapid switch into dysphoric agitation. There's a profound clue waiting to be discovered here. Just hope I don't have to go through any further personal testing to find out. I welcome any and all thoughts. - Barbara

Hey barbara, I haven't tried AMbien yet, I think I'll try Trazodone first (don't mind a good hangover every now and again), if that doesn't work, onto Benzos most likely, we'll see. I was sooo surprised by what the Seroquel did to me, I felt sooo good for a few days (except at nights- which would make sense as the adderall wore off- my doapmine levels would drop). This is why my PDOC suspects akathisia, even at uch a small dose.. because my dopamine levels weren't too great, initially she wanted me to increase the adderall ans spread it out, I just said forget the seroquel!

> What do you guys think?

That's great news that your pdoc is prescribing the traz. I think you'll find it to be very helpful. You'll sleep well and your anxiety level will improve greatly. It might be the perfect med for you. Just be willing to put up with the bonked on the head feeling for a little while. And don't forget the morning situps and pushups. This is the secret to de-fuzzing yourself in the morning. Also, Traz tends to be in the pork-o-genic category so the more exercise you can force yourself to get, the better.

Hey Chemist, I will definetely keep you informed. I think you're right about the Lexapro, I've been very slow in my titration of it. I started in April, and have gone reallly slow, the most recent titration going up to 12.5 from 10. One tihng I've noticed is that adderall can kind of "poop out" my SSRI so to speak, so tweaking the adderall has been a real pain. I can't begin to emphasize how comforting this has been for me. Thank you for taking the time to help me with this! I will keep you guys posted on how this all works out.

> > Hi Chemist,
> > Thanks for the information! I've been on Lexapro at 12.5 for about a month or so now, so hopefully the anxiety isn't from that. My PDoc wants me to titrate up to 15 mgs. I'm a fan of the Lexapro because it's supposedly "cleaner" than other SSRIS, though I wish it was one that caused more sedation. I went back to a lower dose of adderall XR at 5mgs. I'm ditching the Buspar and will try Trazodone for sleep (PDOC called it in for me). I've also heard that it has mild anti-anxiety properties, but at this point I'm not keeping my fingers crossed. I just want some darn sleep and to have the agitation/anxiety stop. I was also given some ativan on hand but have had negative experiences with rebound anxiety from xanax so I'm a bit weary of them, plus there's the addiction potential of course.

Hey Barbara,
thanks for the reply, My PDOC is cool that way, I think she hears from me too much tho LOL. She knows I know my meds and If I suggest something, she's usually pretty open to it. LOL, I can jsut see the trazodone packing some pounds on, the Paxil sure did. Luckily I was scrawny to begin with so it just filled me out a bit, and I was able to lose some of it.> That's great news that your pdoc is prescribing the traz. I think you'll find it to be very helpful. You'll sleep well and your anxiety level will improve greatly. It might be the perfect med for you. Just be willing to put up with the bonked on the head feeling for a little while. And don't forget the morning situps and pushups. This is the secret to de-fuzzing yourself in the morning. Also, Traz tends to be in the pork-o-genic category so the more exercise you can force yourself to get, the better.

> > Hey barbara, I haven't tried AMbien yet, I think I'll try Trazodone first (don't mind a good hangover every now and again), if that doesn't work, onto Benzos most likely, we'll see. I was sooo surprised by what the Seroquel did to me, I felt sooo good for a few days (except at nights- which would make sense as the adderall wore off- my doapmine levels would drop). This is why my PDOC suspects akathisia, even at uch a small dose.. because my dopamine levels weren't too great, initially she wanted me to increase the adderall ans spread it out, I just said forget the seroquel!

differing welcomed and addition information insightful.....i'm just a chemist, remember...i will point out (you know i always have to point something out.....) that it is H_{1} that is hit hardest by seroquel, and (stealing from my PDR) of all the receptors it hits, the IC_{50} for H_{1} is the lowest (!!!), at 30 nM, so no wonder the sedation. a few comments on histidine/histamine. the process of decarboxylating histidine is undertaken by an enzyme that more or less depends on your intake of vitamin B6. also, histidine at physiological pH can be protonated at both the delta and epsilon nitrogens, although the delta form dominates. there might be some correlation in your (i am using the collective ``your'') biochemistry (including stomach acids, lest we forget) that favors the doubly-protonated form and thus the production of a histamine (assuming it stays doubly-protonated after decarboxylation by PLP-powered enzymes) is deficient. alternatively, you might - and i need Larry's help here, so please page him - somehow be overproducing b6, thus making more histamine than ``normal,'' and any introduction of additional histamine will hit you like a brick. enough. all the best, chemist

no, thank you (and the other posters), it's interesting and rewarding to delve into new areas (i speak of myself)...please do keep us informed about the methylation business...let me throw another bone your way: when doubly-protonated, the side chain carries a formal charge. from my work with alkaloids that bind to ligand-gated ion channels of a certain flavor, i know that the binding affinity is greatly increased if one protonates the compound in question. i wonder if a similar antagonism is instigated if the epsilon nitrogen is protonated, and thus competitive binding to H_{1} become more non-competitive? food for thought.........let us know what you discover.......and since you asked, it is chemist, Ph.D. (that and $2.00 gets me a cup of coffee.......).....all the best, chemist

Also, none of these meds change neurotransmitter/receptor functionality that quickly, so dopamine doesn't seem a likely candidate. So perhaps the path is a similar 5Ht2-a blockade as w/trazodone and remeron, but we're still talking serotonin receptors and there's a lag time. It doesn't happen that quickly. My question is, is there also a histamine release which could account for the groggyness? Might this tie in with a possible dysfunction in my histamine levels?

Hey Chemist,
I went to my PDOC today! here's the new "cocktail" we are going to try.Luvox- probably get upt to around 200 MGS
Trazedone- around 25 mgs
Adderall XR- 5 mgs
Ativan as neededI am reluctant to take ativan, but my PDOC is very concerned about my anxiety and agitation of course, both of have been major cornerstones of my depression. We've also discussed the posssiblity of using an anticonvulsant/mood stabilizer to help with anxiety and agitation. Lamitcal came up, I told her I'd consider it.... just gotta watch out for that pesky rash of course! :)
