FILES: This undated file photo shows Viagra pills made by Pfizer. Pfizer has dropped its bid to market its potency pill Viagra over the counter in Europe, the US pharmaceutical giant announced on November 20, 2008. Pfizer "has withdrawn its application to switch the legal status of the 50 mg tablet strength of Viagra from 'prescription only' to 'non-prescription' in the European Union (EU)," a statement said. Prizer said it had decided to withdraw the application "to fully consider" comments from the European Medicines Agency's Committee for Medicinal Products for Human Use, "recognizing that there were some concerns regarding the proposed supply of Viagra 50 mg tablets without a prescription," the statement said.
