I took Zyrtec for some time, as a prescription med. 14 months ago, my blood pressure spiked, for no apparent reason and after 8 different anti-hypertensive drugs, I had no improvement. I was extremely lethargic, I gained 20 pounds, I had severe dizziness, couldn't sleep through the night the last 5 months, my heart would race, constant back ache, and I felt like a snail - no energy to even walk for 10 minutes. Last week, after 3 nights without sleep, and a blood pressure that was so high, I feared a stroke, I went to the emergency room. After a blood test, I was told I was severely anemic! The doctor immediately administered oxygen and ordered a blood transfusion. I continued taking the Zyrtec while in the hospital, and the nursing staff, and my doctor were baffled that my blood pressure would not drop, it continued to rise! All the cardiac tests they performed came back normal, so there's no problem with my heart. The chest X-ray came back clean, no problem with my lungs, I was just anemic, but that didn't explain why my blood pressure would not drop. I came home and forgot to take a dose one night. I slept through the night, but thought "that's because I'm so tired," and the next morning when I checked my blood pressure, it dropped significantly. I couldn't figure out what was going on, I was going CRAZY! That night, I took the Zyrtec, and ALL the horrible symptoms returned. Well, I was pretty sure what the problem was and began researching the next morning. I some information that stated some severe side effects were found after it went to market. The side effects included: aggressive reaction, anaphylaxis, cholestasis, convulsions, glomerulonephritis, hallucinations, hemolytic anemia, hepatitis, orofacial dyskinesia, severe hypotension, stillbirth, suicidal ideation, suicide and thrombocytopenia. That was the LAST dose I took, my blood pressure began to drop the next day and I began to improve overall. I'm scheduled for a kidney function test because that was my backache, the glomerulonephritis; which is an inflammation of the blood vessels in the kidneys. It may be temporary, but can lead to scarring and damage to the point of failure, requiring dialysis and transplant.
