She then did a biopsy and found I had a drug reaction. The only meds I take are Benicar HCT
and potassium. I immediately went of the Benicar and started taking a variety of other BP meds. At first they though I was allergic to the HCT, but then realized it was the Benicar. I am now on Bystolic, but still have the rash. I also take 80mg of Lasix per day. I still have the rash... but was told by the dermatologist it may take up to 6 months for the meds to get out of my system.
