A single package of counterfeit Plavix, a widely used medication to thin the blood of patients after heart attacks, has been caught by the Health Ministry after being smuggled from the Palestinian Authority. The ministry did not know how it arrived in Israel and how many others there are, but it is concerned that others may have reached Israeli pharmacies. The fake Plavix is in an international package, batch number 1476, production date 1.05 and expiry date 1.08. After investigation in the ministry's lab, it was found that the pills lack the active ingredient found in Plavix. It called on pharmacists and patients to take note.
