recently I came across this list of international drug manufacturers.

Many of our generics today in USA come from abroad. It will be very hard
to find data from them. Click on the blue links...to find their webpages.

For what it is worth, I had my Caremark send me LEK brand blood pressure
tablets for my first RX. LEK is in Kosovo. Hardly available for us to call.

I did have good experience with Perrigo..in Michigan. They make most of the
generic OTC products sold in grocery stores and drug stores. They had
extensive gluten information when I called them a while back.

Good luck!
