I began taking Zyrtec for seasonal allergies. I had taken OTC benadryl but it makes me very drowsy so dr. recommended Zyrtec. Took it every day for a week and noticed shortly (within an hour) after taking, I developed a pronounced rash on my hands and feet. Red circular bumps that itched. I did not immediately associate the rash with taking Zyrtec. I had recently purchased new hand soap so I attributed this change to the rash. I stopped taking the Zyrtec and eliminated using the soap at the same. 3 days of no bumpy rash. This morning, took a Zyrtec after a particular rough sneezy morning. Within an hour, the rash is back! The Zyrtec is the ONLY THING that can be causing this reaction as it is the only variable present at the same time the rash is! I started doing research online and am shocked at the reactions people have to Zyrtec. I have never been one to take medicines as I don't trust the pharmaceutical companies and this justifies my position!
