Urticaria
"I took these pills for an attack of hives and anxiety.  I am female and aged 78.  After three days I began to feel nauseous.  I was OK before I went on a long car journey.  After half an hour with my husband driving I began to feel extremely ill.  He managed to stop the car as I was near to fainting and I vomited at the roadside.  I felt as if I was losing consciousness for about 15 mins and felt extremely sick, but could not vomit.   I felt my BP was extremely low.  Finally I felt able to return to our home.  

The doctor who gave me the pills was one I was not known to.  I was a visitor to the town.  I have a history of tachycardia and arrhythmia and was diagnosed with M.E. 8 years ago.  I told the doctor of my medical history."
