I believe it can be a side effect with many of these drugs. I take Cymbalta but not the others you have mentioned and I do find that my once excellent memory is not quite so good. That said I have a cocktail of other drugs so it could be one of the others or the combination. At times I have found that I have struggled a bit with remembering what I was doing and saying but it passed.

I think you need to relax about it because one thing is certain, the more you worry about it the worse it will be!! Check out the RXList website for drug info - they have both professional and patient drug information including the pre and post marketing clinical trial data, side effects and interaction stuff. you can also check out the FDA site and UK equivalent for the reported side effects.

If it doesn't pass in a timescale that you think is reasonable, I would go back and ask your doc.
