The Australian Medical Association has shown its concerns over the issue that some patients may attempt to get a popular weight loss drug over the internet even after restrictions were placed on the product in Australia.
The Therapeutic Goods Administration has warned doctors against prescribing Reductil as it could be potentially fatal to patients with heart disease or hypertension.
Dr Brian Morton from the AMA says people should be careful purchasing the product online.
"The World Health Organisation estimated 30 per cent of medication bought online is counterfeit, so you don't know what's in there", experts feel.
Reductil has become Australia's most popular weight-loss pill, replacing the now-prohibited Ponderax and the restricted Duromine as the most prescribed medicine by the doctors.
Reductil has been proved to cause strokes, high blood pressure, thyroid problems, anxiety and is responsible for least one death in Australia. In addition, the circular has cautioned people that the fat-busting drug could harm the very people it was aimed at - the overweight.
