... white tablet with the logo LU H13 to a much smaller tablet with the logo L 32. We took both pills to the pharmacist, who said it was the same thing. However, I now have a measles-looking red rash which my PCP says is an allergy related to skin treatments like lotions, etc. I am wondering if the inactive ingredients in the new generic amlodipine have changed to something I am allergic to. I have been unable to learn what the inactive ingredients are. I am now taking prednisone, which is having no effect on the rash. Is this a common problem?
