Cody,
I just started on 5mg Lexapro yesterday too. I'm new here and found the group by searching for lexapro. I was happy to see your post. This is my second try at antidepressants. I had a very tough time on zoloft and now I'm apprehensive about this one too. Since we started the same day maybe we can be lexapro buddies :-)and help each other get through it. It's hard to judge my s/e because I had been feeling pretty bad the last few days. I just feel kind of out of it.> Alaskagirl, thanks for your support. Sometimes I feel like I'm groping in the dark. It's good to hear other's experiences. I started Lexapro at 5mg. this morning. Decided against doing the 2.5mg. Rather get the adjustment over with. So far, so good. Not too many s/e. Mild headache, tightness in chest, some palpatations. Will keep you posted.

No, logic doesn't explain everything but it's pretty useful in trying to sort out complicated issues. I'm sure no-one would advocate deliberately not being logical.
It's difficult to generalise from the individual experience of a relatively few people, which is why scientific trials exist. It's an attempt to answer questions without bias as far as possible. My view is that if research has been done which fails to support a given argument, one should not treat it as proven fact, and I am concerned that this is what is happening. If there were clear evidence for the 4 to 1 argument I would of course accept it, as I accept very many things in psychiatry for which a mechanism is unknown. But the evidence isn't really there.
I'm not sure I really follow your argument about the implications of the results for 10 and 20mg of escitalopram being the same. I compare them with 20 and 40 mg of citalopram because these represent the same amounts of escitalopram, just in the presence of r-citalopram.
80mg of citalopram would be 40mg of escitalopram plus 40mg r-citalopram, and we have no 40mg escitalopram group to compare it to. I'm not sure why one would pick this particular dose to compare with anything.
> I'm afraid logic doesn't explain everything. If 10 mg of lexapro was found to be equivalent to 40 mg of Celexa (which my and a lot of other people's experience confirms), you need to accept this. Perhaps the inactive isomer affects the absorption or otherwise interferes with the effectiveness of the active isomer. Just because we don't understand the reason does not make it not so. And your comparison is not valid. If 20 mg lexapro is no more effective in the study than 10 mg, that doesnt suggest that 40 mg of celexa would be no more effective than 20 mg. Rather, it suggests (but does not necessarily mean) that 80 mg of Celexa would be no more effective than 40.

Kinikia,
I'd be happy to be your Lexapro buddie. This is my 2nd try at Lexapro and I really hope it works. So far, I don't feel too bad. A little hyper during the day, but last night around 8 pm I got so sleepy I couldn't keep my eyes open. Still not sure if I'm having withdrawal from the Remeron I was on. What are you taking the Lex for? Depression, anxiety, both? Keep me posted on how your doing.

The study that Forest did and that the FDA oversaw indicated that 10 mg Lexapro was equivalent in antidepressant effect to at least 40 mg. (Are you suggesting that there was no such study and that Forest's claims are fraudulent?) This is why psychiatrists (American ones at least) have been instructed to prescribe at a 1 to 4 ratio. And so far, it seems to be working. It's the patients who've been prescribed at a 1 to 2 ratio that are reporting problems. That's why I'm comparing 10 and 20 mg lex to 40 and 80 celex. I thought it was strange at first as well and certainly did not expect to feel any changes when I switched meds. The hypothesis is that the inactive isomer inhibits the effectiveness of the active one. Have you tried both drugs?

My understanding of what Dr. Dave is saying is that since Lexapro 10 mg and Celexa 20 mg contain the same amount of the s-isomer, then they would be therapeutically equivalent. But every study done to date shows that Lexapro 10mg is at least as effective as Celexa 40mg, and that is what many people on this board have expressed their experience has been as well.
Just because the s-isomer is proportionally present in both doses, this doesn't make them therapeutically equivalant because that theory does not take into account the presence of the r-isomer in Celexa, which Lexapro dose not possess. The r has been proven to be ineffective in treating depression, but we do not know if it hindered the active agent. (This would probably take a lot of money and time to prove. I don't even know if it's possible to prove scientifically.) No one has clearly proven that it hindered, but many theorize that it must have, since 10mg Lexapro is at least as effective as 40mg Celexa (NOT 20mg) as one would expect.

I'm not suggesting there was no such study - that's why I quoted it and discussed the meaning of its results. Nor am I suggesting the study is fraudulent. What I am suggesting is that 'instructing' psychiatrists to treat escitalopram as four times as potent by weight does not bear examination when you look closely at the evidence. If there has been another study apart from the Burke study which indicates this, I would be glad to know of it.
I have used citalopram extensively for many years and it is extremely useful. I am waiting for convincing evidence, or one independent body to review the evidence and state there is a significant difference, before using escitalopram. It is a generally accepted principle (at least with the psychiatrists I know) that you don't start using new drugs unless a case can be made for doing so. I don't think the case has been made. This appears to be the opinion of all four independent bodies that I know of which have reviewed the data.

I wonder if you could let us know what the evidence is that r-cit 'can attach to receptor sites not allowing the s-cit to attach, therefore inhibiting metabolization'. The only relevant site with respect to SSRI activity is the serotonin re-uptake transporter, and r-cit has only 1/30th the affinity for it that s-cit has, not enough to significantly compete. I am also not sure why s-cit would have to be bound to a receptor to be metabolised, or what receptor that would be. It sounds like you've seen some important new data, and would be very grateful for details.

Hi,
well I have news for you about this matter.I took JUST 10MG this morning instead of the 30MG which has been making me feel really ill. I feel MUCH BETTER...
I dont want to drop from 30 to 15mg in one go, so Im going to move to 20mg as from tomorrow and see how I feel.
But I think I am proof that the 2:1 ratio is not true.
On a couple of occasions, I took a double dose of my 60mg of citalopram (forgot I had taken it, and took it again if you understand). On the two occasions I have made this error, I was really ill both days. Red face, really trembly, jitters, etc etc..
Well, the feeling Ive been getting the last two weeks when taking 30MG lexapro (half my 60mg dose of citalopram) was the same as when I doubled my citalopram dose. I just feel like a fool that I didnt realise earlier that I was on too high a dose of lexapro. I just thought my anxiety had come back!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Well, I will keep you posted on how I get on on 20mg (which if the 4:1 ratio is true), will still be too high and I should move to 15mg... but I want to play it safe.
Cheers

I AM NOT TAKING BOTH OF THEM!!!!!!!!!!!!!!!!!
I switch directly from 60mg citalopram to 30mg lexapro, then two weeks later started to become really ill.
I thought it was my anxiety returning, but in fact, I am pretty sure now my dose of lexapro was way-to-high.
Cheers

In my experience DOSE HAS EVERYTHING TO DO WITH IT.
I couldnt quite cope on 40mg citalopram. 60mg citalopram made me feel almost totally well. I tried 80mg citalopram for a month, but I couldnt tolerate the extra amount. When on a couple of occasions I accidentally took my 60mg dose twice in one day (=120mg) I was quite ill.
Since i SWITCHED to lexapro, 30mg has been way to high a dose for me. Im going down to 20mg from tomorrow and leave it there for a while until I know the dose is either too high or right for me.
I have tried all the SSRIs (except Luvox), and citalopram was definitely the best for me.
Im just hoping that on a new lowered dose of lexapro that my sexual side effects will diminish which was the only real problem I had with citalopram.
Cheers

You are absolutely right.
When I switched from citalopram to lexapro, it was like going on an AD where you're too buzzed up, red faced, sweaty etc... The only problem was for me, that when I went from 60mg citalopram to 30mg lexapro, this "coming-up" was really bad - but I now think that was purely because lexapro is much more potent and 30mg lexapro IS MUCH HIGHER DOSE than 60mg Citalopram

Please see my "I AM TAKING 30MG LEXAPRO" thread if you wouldnt mind, as I would value your views.

Hi Pharmrep,
I would just like to say that I value your input on this forum as I have found your posts to be useful and informative, and I believe that the reasons for lexapro being a big improvement over celexa may be true.The fact that moving from 60mg citalopram to 30mg of lexapro (and finding the dose way too high) proves to me that lexapro is definitely more potent that citalopram.

In reply to lexapro 10mg, posted by corrina on October 2, 2002, at 21:46:12
Hi Corrina,
my advice to you is that you are likely to suffer some side effects at the start of your course of medication.Try your best to stick with it if it becomes uncomfortable because they do go away.
Dizzyness and sickness are very common, both of which I have suffered myself, but have always gone away after 2-3 weeks (maybe less for lexapro)

Thank you all for the advice im gonna try and stick with it and see what happens, I was also put on some sleeping pills and thinking I was getting dizzy from that but now I know its the lexapro. im hoping this works for me cause my depression is very bad and actually I found when I first started this Lexapro my depression was even worse the first couple days but that no longer is the fact, I found that this is making me kinda mellow which is good for me cause im always Ms. Speedy at everything I do and im kinda feeling a little relaxed.
I will keep everyone informed on my progress with this med. And Thank you again for the feedback!Corrina

**** 4 to 1 ratio? that is wrong...Lex 10mg vs celexa 40mg is a 2 to 1 ratio not 4 to 1 (dont forget to subtract the r-isomer). anyway...forest is not promoting 4 to 1 either...10mg is 40 yes...but 15=60 and 20=80 is not exact...10mg has been fine for many 60mg+ people (not just celexa...all high doses of AD's). if you already got to 30mg fine, then dropping to 20mg over 2 days or so, then 10 should be fine (not associated w/ discontinuation syndrome) keep us posted.

What do you mean 40 celexa and 10 mg of lexapro isn't a 4 to 1 ratio? I'm not comparing the strength of the isomers. I'm comparing the amount of drugs needed to achieve given antidepressant effect. I guess what you're saying is that the s isomer when given alone is twice as potent as the s isomer when given in combination with the r isomer. Seems like a strange point to focus on. People want to know how much lexapro to take if they're on Celexa, and for that purpose, the key a ratio is 4 to 1 (at least roughly).

Thanks Pharmrep. Im grateful for your help. I will drop to 20mg for a couple of days and then to 15mg.
I was worried about withdrawal symptoms to drop straight down to 15mg from 30mg.
Its amazing how IN ONE SINGLE DAY dropping from 30mg to 10mg stopped me from feeling ill - but I only dropped to 10mg for today because Ive been on so high a dose...
