If I got a "repackaged parallel import drug" at the pharmacy, could it mean that it is a fake?

You probably received a drug from parallel imports (from another country) - this is a completely safe, legal and standard procedure that allows m.in to sell medicines at more favorable prices. I will quote an excerpt from our article: "It happens that the same drug, produced by the same manufacturer, may have a different price in different countries. It happens that it is much cheaper abroad than in Poland. This may result from different logistics or production costs, competition existing in a given market or other local conditions. In such cases - even after taking into account additional costs - it may turn out that bringing it to the needs of Polish patients will be profitable, because in the end the price of the product on our market will be lower. That is why sometimes a drug bought at a pharmacy may look different than usual. We call this procedure for importing medicines from abroad parallel importation." "In other countries, the same drug may or may not be distributed under a different trade name. In order for the Polish patient to receive a properly labeled and described product, the entity involved in importing performs a certain procedure. The interference consists in repacking the drug in a new carton."
