In reply to Lexapro side-effects - where's the evidence? » pharmrep, posted by dr. dave on September 27, 2002, at 6:13:23

***** Nobody has ever said r-cit was inert or is where the side effects are...it just isnt contributing towards treating depressive syptoms (as seen in sanchez study). all of the studies show 10mg to have "s/e comparable to placebo" which is definitely less than celexa or any other AD. I'm not sure who you mean when you say "they"...but it's not just forest stating that claim...it's every study done so far...with the backing of the FDA.
>
> They clearly fail to demonstrate any significant difference. Despite repeated calls for any other research data which might back up the claim, none have appeared. So it is puzzling that this claim is again presented as fact.
>
> The repeated statement of unsubstantiated claims leads to confusion. For instance, it has been said that r-citalopram cannot be inert because it is blamed for side-effects from Celexa. While it is true that this is claimed, there is no evidence to show that it is true. Removing r-citalopram does not cause a significant decrease in side-effects. But if the claim is made often enough, people begin to take it as fact and make deductions which stray further and further from what the research actually shows.

> If there is now evidence that Lexapro has significantly fewer side-effects than Celexa, It would be very useful to see it.

> > ** great question. 10mg of Lex is at least as efficacious as 40mg of cx...but with less s/e, less drug to drug interactions, and less discontinuation due to adverse events, and will work as fast as 1-2 weeks for most people. It is linear, however...5mg will not work as fast, and is not the recommended starting dose. In general, for most drugs many doctors reduce dosages to avoid side effects, but since Lexapro at 10mg is "comparable to placebo" it shouldnt be needed. In the Dr's I've seen...I would say 95%+ are starting w/ 10mg...only a few have gone to 20mg (only 2 weeks out now) and maybe a few Dr's are just "set in there ways" and are starting with 5mg (for a week or so...then up to 10mg) So far...I have only heard good responses from them, but most of their patients havent been back for their "monthly" visit...I'll hear more in about 2 weeks or so.
> > PS...the starting dose for celexa was 20mg (62% of patients stayed there)...40mg was at about 30% (for a total of 92% of all Celexa prescriptions...the last 8% were at 60mg or higher.) I think Lexapro at 10mg will be effective for 80%+ of patients...then 15mg+ will make up the last 20%

*** you are right...Dr Dave wont agree with this point...Celexa is a racemic mixture with "mirror" halves..r-cit. and s-cit (50/50 mix) the r-cit does not contribute towards treating depressive symptoms at all (see sanchez study) and actually inhibits the s-cit (lexapro) from its full potential. it wasnt expected at first...but 10mg is at least as efficacious as 40mg of celexa.
But your conclusion is based on the idea that 10 mg. of Lexapro is equivalent to 20 mg. of Celexa, whereas the company claims that it's equivalent to 40 mg. Am I wrong? I am curious, however, why isolating one of the isomers would make it 4 times stronger. I assumed that the two isomers in celexa were present in a ratio of 1:1, in which case you'd assume (assuming that the less active isomer is not active at all) that the isomer would be twice as strong, not 4 times as strong. Unless the non-active component actually INHIBITS the active component. Or perhaps the assumption that they are present in a ratio of 1:1 is wrong.

I just switched from celexa to lexapro... on celexa, i had some sexual side effects, mainly less desire and ejac.problems... i switched to lexapro recently - is rash (itchiness really) and/or shortness of breath possible side effects? Are there any ingredients in lexapro that could cause this? I never experienced either on celexa... also, does lexapro REALLY help the sexual side effects? How long to be on it before you notoice a difference?

> *** rash/itch...very low %, not mentionable, might go away with time/ same with shortness of breath. there are no "new ingrediants" in Lexapro. as for sex s/e...it is an ssri, and they are a class effect for all ssri's. It was listed as 9% for ejac delay...but might be higher. for all side effects and efficacy, you might see its true color in 1-2 weeks, but give it 3-4 for a fair trial for yourself. good luck and keep us posted

Hi curiousguy,
I would think that you should mention any new side effects like this to your pdoc and discuss with him whether or not you should continue. It may or it may not be related to the med, but you should still probably discuss it with a doctor.

For clarification, was that 9% of the males or 9% of all participants?

the shortness of breath/itchiness that curious guy mentioned sounds a lot like I feel when my allergies are kicking in. Since neither is listed as being commonly reported s/e's, it's possible that these symptoms are totally unrelated. Also, when I feel stress/anxiety, I do feel short of breath also. Anyway, just my two cents.

Dizziness, nausea, the nausea is the worst. If my stomach gets empty I feel close to losing it. I just started the Lexapro a week ago. So I am not used to it yet. I was on Effexor (spelling) for close to six months, maybe more. It just wasn't doing anything anymore.

I switched from Celexa to Lexapro about 2 weeks ago. I think it's making the Wellburtin ? and Neourtin ? kick in harder. Almost died from the withdrawal of Celexa-- 30Mg. This is the best clinical trial you can have, with real results. Sorry about the spelling, wasn't near the jars.

I started on 10mg Lexapro about 2 weeks ago. Prior to this I was taking 150mg of Effexor, which was adequetly relieving my anxiety and depression, but had unwelcome side effects.
I am pleased that I feel no side effects with Lexapro, but I am not feeling much in the way of anxiety/depression relief with it. Is it time to ask my doctor about trying a higher dosage? How long should I give this?

> We need more drug clinical trials where the people recruited are those with SEVERE melancholia type major depression, not dysthymics and moderate depressives.
Gorman did a subanalysis of severe depressives (see Gorman et al., 2002, CNS Spectrums) as part of the Lexapro pooled trial. Also, Gorman did an analysis of severe depressives that was presented at the recent CINP meeting in Montreal.

** you said 1 wk now for lexapro...did you just stop effexor? what dose?...dizziness and nausea can occur from abrupt discontinuation from effexor (and paxil). hopefully you can hang in there...do you see any benefits from lexapro yet?

How long should I give this?** good q...glad you are experiencing better tolerability...here's the scoop. lexapro 10mg works in 1-2 weeks for most people, but as i have found, that's only a general statement to most here...for a fair trial, give it 3-4 weeks, if still not doing it, bump to 15mg for a couple weeks, then only higher if still not quite working.

Generally, those types of figures are sex-specific. I.e., the demoninator would be men only.

Yes, I've been on Lexapro (10 Mg) for 2+ weeks. My doctor switched me from Zoloft which I was taking for panic and depression. I have been sleeping better on the Lexapro and no more delayed orgasm! Yippee! I feel great. Lots of energy and really can't identify any side effects.
I have tried Serzone, Effexor as well as Zoloft and had delayed orgasm on all of these drugs.

This is my first post here. I have been on Remeron (45 mg) for 3 years. My doc wants me to try Lexapro. My main problem is extreme anxiety. I tried the Lexapro (5 mg.) a few weeks ago but quit after 3 days because of side effects. I want to give it another try at 2.5 mg. because of reading that the side effects may go away after 4-5 days. My question is, what is the best time of the day to take it. Would appreciate any input.
Thanks,
Cody

I'm surprised you had any side effects at all from Lexapro at 5 mg. Are you sure it wasn't withdrawal from Remeron? In any case, they will almost certainly go away. For me, it doesnt matter what time I take it, but if the side effect is drowsiness, take it at night, and vice versa.

Not sure if it was Remeron withdrawal. I'm down to about 22.5 mg right now. I think that I'm very sensitive. Had to increase my Remeron very slowly. With the Lexapro, I was very nauseous, headache, spaced out feeling and my heart was racing. Can't afford to be down for long. Have husband and 4 children to take of. But I think I have to give it another try, because although the Remeron really helped with the anxiety, I have no energy or motivation for life. Doc told me to increase ativan while I'm adjusting to Lexapro. I really hope it works.
