Cost is the major difference.
I generally use Naproxen sodium for cost reasons. Na Shouldn't interfere. I have been noticeably moodier also. The reaction included hives, swelling in various areas of my body, loss of appetite and a general very sick feeling. I have been taking Naproxen for about 8 months and previous to this with no ill effect.
