The Swiss Agency for Therapeutic Products (Swissmedic) said that counterfeit Harvoni that was discovered in Israel had been shipped through an importer in Switzerland. The regulator is now working with other European authorities to figure out if the fake Harvoni packs also went to other countries. Swissmedic said the plastic bottles contained pills which were white coated, instead of the "genuine yellow film-coated tablets." It said it was aware the consumers had been buying the drug abroad because it is so expensive and in limited quantities in Switzerland but warned consumers there is no way to be sure what they are getting online is authentic.
