Went to the doc's with a bad deep cough had for about a week. I was prescribed an antibiotic, eye drop, and an antihistamine. Went to local drug store found out insurance would not pay for antihistamine because it was the same thing as OTC Zyrtec and that the drug store had a generic brand which was cheaper. Started taking it on a fri. night all went well until the following Thur. night at work. Arrived at work normal time then roughly one hour into my shift I notice sweating, dizzy, and not aware of my surroundings, when suddenly I found myself passed out on a hard concrete floor flopping like a fish out of water. Taken to ER were they performed CAT scan, MRI, and very painful spinal tap. All came back clear. After a stay in the hospital fri I was looking forward to being discharged sat morning when all of sudden it happen once again. In fact it happen three times sat. What was it you ask? My heart had STOPPED first time 5 seconds, second time 11 seconds, and the third time with my Wife watching my heart stopped for a full 18 seconds. Awoke to the sights of several Nurse's with difb in hand ready to shock me back. Rushed to ICU my heart than began racing to 170 – 180 beats a min. had to get med’s. to slow it down. Was schd for a pace maker. Final diagnosis ZYRTEC! The hospital Doc., Cardiologist as well as my PCP agreed.
