Generic brands- What is the one that's worked best for you?

Hi all!

I've done some research and have heard that different generic brands of medications such as Lexapro, Zoloft, Xanax, Prozac, Paxil etc. have worked best that others. Or upon switching generic brand from one pharmacy to another there are adverse reactions even if they are for the same dosage and medication.

I would like to hear what brands have worked best or have not been great. I think this would help others a lot!

I take brand name Effexor, but when I was taking the generic, the only manufacturer I could take was Teva.

I also take generic zoloft and my pharmacy orders me in Greenstone...couldn't take the Cipla Maufacturer.

Sylkn question for you! Which pharmacy is ordering the greenstone for you? I called my pharmacy and they said they didn't do that which I think isn't right. I filled with Walgreens but have been on the search for greenstone.
