1, packaging is different: Roche Tamiflu genuine packaging should have Roche logo and drug name, and the words on the packaging box and instructions should be clear and unambiguous, free of typos and grammatical errors. Fake goods will appear unclear, vague, typos and grammatical errors.
2, different barcodes: Roche Tamiflu authentic barcodes should be independent of each other, there is no duplication. When scanning bar codes, genuine products should be able to identify accurately. The barcodes of fakes are all the same, there is no difference.
