Finally....I’m starting to feel alive again. Venlalic seem to be the only brand of Venlafaxine that

Posted , 4 users are following.

So I’ve been on a medi-go-round since Nov/December.  I was prescribed venlafaxine generic tablets, however, they made me extremely exhausted.  So, I was switched to extended release capsules 150mg.  As soon as I started taking them, I had anxiety come on. I lost weight etc. I stuck it out as my psychiatrist advised me to. After taking them for 4/5 weeks, I decided to up the dose to see whether it was that that was causing the problem.  The anxiety stopped for a few days, perhaps a placebo effect, then it kicked in again.  I went back to the doctors and he advised me to switch over to the XL tablets (rather than capsules). I was on the XL tablets a few years ago and they worked well. 


So, when I went to the chemist, to make up the denomination of the MG they had to give me two different brands of venlafaxine.  As soon as I started taking them, they caused really bad insomnia.

So my last resort was to ask the doctor if he could specifically prescribe me the brand of tablets that I was on a few years ago which is Venlalic. 

I have been taking them now for just over one week and I can’t believe that within hours of me taking them, the anxiety has completely gone, I can think clearly.   It’s like a miracle.

What worries me though is that not only do we have to jump from med to med, but we actually have to try out the different brands too which is wrong. 


I’m lucky that my doctor actually agreed to write out a prescription for a specific brand.

    Hi Kerrie, there's a similar problem with Sertraline, different brands give different results/side effects. It's something more people should be aware of especially the doctors!

    Interesting post from a pharmacist about generic drugs taken from the link below:

    Post by "sarah17507"

    "Hi all

    this is such an interesting problem. Here are a few views of a pharmacist, if it helps!

    We pharmacists have a sort of standard answer when patients come back and say the cheap generic we've given them (because that's what's on their prescription) doesn't agree with them or doesn't work or gives them side effects.....we say all generic drugs have to be made to certain standards and must show 'bioequivalence' to the original product, I.e. Lustral brand in the case of sertraline, and we are unable to give you lustral due to costs, and we say this all in good faith, because in honesty, this is all true. BUT.....I for one, know that the reality is different to this, as we are all different! And all the generic copies are bound to be slightly different as other posters have said, the inactive ingredients DO contribute some activity, especially with regards to allergies to colourings.

    So, I just wanted to say, I do have sympathy and wish I could give each patient exactly the brand they feel best on, but I cant! If the script says 'sertraline' I can give any brand and will be reimbursed for cheap sertraline, a set price. If the script says 'lustral' I can only give you lustral, and as such will be reimbursed the set price of this.....a lot more than generic. I have worked in loads of different pharmacies as I'm a locum, and can say that I advise you all to shop around, as different pharmacies vary in their ability to obtain your preferred generic always ask the pharmacist if it's something they can do.

    your doctor will be under pressure to reduce their prescribing costs so it is unlikely they'll start prescribing you the brand of lustral, but I do know some patients seem to get lucky here, and seem to have persuaded their doctor to write lustral. Well done to them I say! Often, the hospital doctors will be used to writing the brand (effects of company drug reps are influential) so you start on lustral, then your GP takes over and of course you feel fobbed off with cheap drugs. I believe patients when they say a generic has caused their condition to worsen, but I can't do anything about it if you want the brand, only the prescriber can. But i can try and obtain a particular manufacturers generic for you.

    another point is, some large pharmacy chains DO supply you with lustral even if your script says sertraline, as they have a deal with Pfizer as they buy in large quantities, so just to add even more confusion, some days you may well receive lustral when you weren't expecting it!

    Ive had so many people specifically request Dr reddy brand of other drugs, eg., clopidogrel, saying it's the only one they feel works, and funnily enough, also loads of ppl saying 'never give me Dr reddys brand' what does this tell us!? We have so much choice in this country and our wonderful NHS gives us so much for free, we are very spoilt if we can choose the brand of our tablets. I believe Dr reddys are made in India though, and I can only imagine their GMP (good manufacturing practice) is shall we say different to the uk!

    always bear in mind your condition can change, and it's very hard to prove causation, as it could always be coincidence, so don't always blame the generic drug, but that said, I do believe problems can be caused by generics and your doctor should listen to your concerns. Fakes and counterfeit drugs are a separate issue though, generics aren't fakes. They're legal and genuine and tested. Always report adverse effects via yellow card system.

    sorry to have rambled on! Good luck all."

    When I was put on generic Venlafaxine my body knew straight away that they were different from the brand Effexor.  I asked my doctor to prescribe Effexor brand name.  Pharmacist weill tell you they are identical, but we who take them can feel the difference.  I agree entirely with you generic are definitely not the same.  We know don't we?

    Glad your doctor is like mine was and is prescribing Effexor only.
