birth control
"I had been taking the name-brand of this contraceptive for probably 18 years.  Then my insurance decided it would only pay for generic.  I started this one in October.  By Thanksgiving I had a raging allergic rash on most of my body.  ER dr wrongly diagnosed me, and after 2 other dr visits and a biopsy, they discovered it was an allergy to this drug.  It is now mid-February, and after 3 rounds of steroids, I STILL have some of the rash.  Torture for sure!"
