About a year ago, I was prescrived Diovan and the dosage was increased until about a month ago increased from 160mg to 320mg. I started experiencing a body rash to the point of not being able to sleep, I stop taking the med. and now on the 2nd week the itch continues, after few visits to the dermatologist and my general physician he switched the medication to Avapro, and for 3 days I can't sleep, the itch continues and last night I experienced itch around my lips palm of hands and bottom of my feet, fatigue and could not sleep at all, anybody have these same effects?
