Just had a stent operation in Suzhou, and the doctor said he would take a medicine called Polivik. A box of 147 yuan can only be taken for one week. It's too expensive. Where can I find something cheaper? Plavix is imported, and the ingredient is clopidogrel. 75mg per tablet, 7 tablets per box, price 1.40 yuan. There is a kind of clopidogrel called Taijia in China, and the content of each tablet is 25mg, so I want to take three tablets at a time. I can't remember the price. It's cheaper than Polivi.
