For the several days I have takent the new one venlafaxine, I have been extremely dizzy. I have often had low levels of "vertigo" but this is off the cahrts. Could it be caused by this med change? Is it a problem to be concerned about?

I was intolerant to the generic. According to scientific data they have to be % close to the actual ''drug recipe'' and many have side effects with generic. My doctor had to write a referal to the pharmacist and my insurance company stipulating that I do not tolerate it. Now they have no choice and they are paying the brand name Effexor XR for me. As soon as I took the effexor back, the side effects went away. Good luck

Hello, I was switched to generic without notice and I was spiralling downward and had no idea why! The only change I could think of was that when I was paying my dispensing fee they mentioned it was generic and my benefits only covered generic. So i figured they would never give me something that didn't work exactly like the brand name! Well I was wrong! I spoke to my doctor and she was actually flooded with complaints about this new 'generic' effexor! She emmediatly prescribed "brand name only" Effexor and had to write a note for the pharmacist etc. I began to feel back to my old self pretty quickly.
So my doctor explained to me that Effexor has a patented time release system in it. Try as they might, the generic people can not seem to emmulate it. I find it rather discouraging that they market their product as the same as the brand name! It just doesn't seem right to play with people's lives like this! If I hadn't figured it out as quickly as I did I would have been in serious trouble.

I found that I'm experiencing the same thing! I'm on 225mg of Effexor XR, and once switched to the generic (it is the extended release too), I've started feeling as though I'm withdrawing, even though it appears to be the same dosage.. I've been dizzy and very irritable and sensitive, so I've been wondering the same, if there's a difference at all, that could be making me feel this way... Let me know if you figure it out, I'm going (back) to the doctor!

All of the websites say that the generic version and the name brand are the same. With that said everybody is different, all of us have different chemical make ups, I would start with the pharmacy and make sure the correct Mg dosage was administered. If it was and the change was due to insurance then you need to involve your doctor.

I took the generic venlafixine hcl last summer. I took it for anxanity attacts because my husband had passed away. I took it for 3 weeks and one morning I woke up and saw about 5 people in my front yard. I called the Sheriffs dept and let my german shepherd dogs out. Well needless to say the dogs did not react at all. The sheriff & deputy came out and saw no one. I just stood on the front porch & cried. Thats what venlafixine did to me. Then I found out that I was not the only one who had this reaction. Never again. Thats what generics do to you God help us all Sheba3878

I'm on the phone getting my Effexor XR prescription renewed, and I was offered the generic. I agreed to it until I saw the posts above. It seems that perhaps it's better to wait and see how others respond before switching. I'm interested in hearing about anyone else's experiences, good or bad.

I have been taking the generic form of the extended release for about 1 month. No difference from the brand name. Make sure that if you're on XR you get the extended release generic. Otherwise you're in for side effects because it doesn't last in your system like extended release. When taking an immediate release version the doses need to be broken up so the desired amount in your blood stream stays continuous. Hope this helps!

Thank you to all who have answered to the posted question. Yesterday I called my pharmacy to ask about differences between the 150mg ER Venlafaxine tablet versus the 150mg ER capsule. I have never had an issue going between brand name Effexor xr 150mg and the venlafaxine ER tablets, but this switch from tablet to capsule has been grueling. I feel light-headed, sick to my stomach, and have had headaches.
I have been on the drug for 10+ years, and because of insurance changes have had to switch back and forth. Now the pharmacy gave me the new ER capsule. This sucks!

If you were on Effexor XR 75mg you must be given the newly approved generic version by Teva - Venlafaxine HCl - extended release capsule 75mg.
This is the only generic version that is interchangeable with Effexor XR.
Check with your pharmacist that you have been given the correct generic.

Mine is the worst scenario... Starting with the generic up to 225mg, feeling much better by the fourth week and after that my doc switched me to the brand name 225mg, and three weeks right now I'm going crazy. I paid 300 for the brand name for nothing... I feel like I'm starting a new med directly on 225mg... my anxiety is terrible and insomnia (I didn't have any of those with the generic, which I started slowly). I hate psychiatrists...

I don't like generic pain medications (I have been through five kinds) I would say from my experience every person's body is different what might not be a problem for you might make me really have problems, now I am not trying to scare you if this continues please contact you prescriber and tell him what has happened far better if this does not work then maybe he can intervene my best wishes and prayers
