However, in a letter to the European Medicines Agency (EMEA), Pfizer said that it has decided to withdraw the application in order to fully consider comments from the EMEA’s Committee for Medicinal Products for Human Use (CHMP), recognizing that there were some concerns regarding the proposed supply of Viagra 50 mg tablets without a prescription in the EU.

"[25] A careful review of pooled data from clinical trials containing well documented information about the dose and duration of exposure to the drug for a large number of patients, yields no evidence for an increased risk of non-arteritic anterior ischemic optic neuropathy or other adverse ocular events associated with PDE5 inhibitor use. Rare but serious adverse effects found through postmarketing surveillance include prolonged erections, severe low blood pressure, myocardial infarction (heart attack), ventricular arrhythmias, stroke, increased intraocular pressure, and sudden hearing loss.
