On Monday, Britain's Medicines and Healthcare products Regulatory Agency (MHRA), said Avandia should be pulled from the UK market because of concerns that the drug could increase the risk of heart attacks.
They said an independent panel of experts had advised that the risks of the product outweighed its benefits, and that the drug should no longer be sold in Britain.
The body said it had sent a letter to doctors in July advising them to consider alternative treatments.
Avandia, made by pharmaceutical company Glaxo Smith Kline (GSK), was approved by the EMA in 2000 to help lower blood sugar levels in patients with Type 2 diabetes.
GSK has maintained that its extensive research involving over 50,000 patients has shown that Avandia does not increase the overall risk of heart attack, stroke or death compared to other diabetes drugs.
"We continue to believe that Avandia is safe and effective when it is prescribed appropriately," the company said in a statement.
But the British Medical Journal was critical of both GSK's research methods and the European approval process, outlining what were described as multiple problems associated with Avandia's safety in a report published on Monday.
In the US, the Food and Drug Administration (FDA) has placed Avandia under scrutiny since 2007, when a study suggested that patients taking the drug were 43 per cent more likely to experience a heart attack than those taking other diabetes drugs or no diabetes medication at all.
