I am taking paxil, but the generic form.

I have been on a specific generic form from a specific pharmacy for about 3 months now. Due to limited money, I had to order paxil from another pharmacy and I got a different type of the generic drug.

The actual generic drug had 2 different names, one was something like parotin and the other one just said paroextine HCL (which is the scientific name for the ingredients in paxil).

Is this a health concern? Is it a bad idea to mix taking different generic drugs of the same actual drug?
