i have taking this med(3 caps. of 75mg ) for about 2yr. the side effects are blurred vision, constipation and a few others that are minor to manageable. the rash however started a few days ago in an area about 4-5 sq inches,and seems to spread a little outside the main area. the itch is intense. the rash seems to be an insignificant side affect in the big picture of things. your input would be welcome.
