My skin would itch bad meaning I had to take Piriton. When I came off Clopidogrel after a year, the
half life is around 8 hours. My dosage was 75mg daily, meaning after 48 hours I would still have around a mg in my body. The itching continued for about 2 weeks after. I was also put onto ace inhibitors (Ramipril), and they didn't cause any problems the first time. I stopped them under the Doctors orders for about a year, but then needed them again before having more stents.
