I was taking the brand name Wellbutrin L and due to insurance limitations was given the generic brand. I felt horrible. I was irratable beyond anything I had ever experienced, I felt bad physically, forgetfullness, etc. So I purchased a one week supply of the brand name just to be sure and there is definately a difference. My problem is I can't afford the brand name and the generic I was taking had adverse affects. Is there a difference in the quality by manufacturers?
There isn't a difference in the medication or manufacturing of the medication but they each contain different inactive ingredients (the ingredients that hold the pill together) and you could be having a reaction to one of those. You body may be sensitive or tolerant of the inactive ingredient and that's why it feels like it's working differently. There are strict guildlines given by the FDA on manufacturing generic drugs, so don't be alarmed that you haven't been given a "good" drug.
GlaxoSmithKline offers a patient assistance program, you can contact them at 866-728-4368 and see if you are eligible and they may help you with the cost of the brand name.
i took generic wellbutrin to quit smoking and had to stop because of severe insomnia, horrible itchy rash and increased hostility. i've been off it for 3 weeks and the insomnia and rash are still present - in spite of my taking benadryl like crazy. pharmacist said it could be due to the "fillers" i.e. dye, etc they use in generics. nonetheless, neither the pharmacist or my dr think this is related to the bupropion. i know it is.
Generics are not identical to brand name, the FDA standards only require that a generic function the same for the majority of patients. (I've seen numbers between 66% and 80% minimum.) Also the inactive ingredients can be different so allergic reactions are possible. Ask your pharmacist to order a different brand when you refill. The pill identifier link here is good for finding out which one you are on now.
I also was taking the brand name Wellbutrin and had to switch to generic because I no onger have insurance. The pill is a large lt. purple and I even checked to see if it might be the wrong medicine because I started feeling awful as soon as I started taking it. There seems to definately be a difference. It is by the manufacturer Sandoz and I would not recommend it.
