Shane Warne has admitted the banned diuretic which earned him a 12-month ban was not the first time he had taken a fluid tablet.

Warne said he had taken another fluid tablet given to him by his mother Brigitte in early December - before his shoulder injury and more than a month before taking the banned diuretic which threatens to end his career.

The leg-spinner said a previous drug test had shown up small traces of similar substances to those which had emerged in the January 22 sample, for which he was called before an anti-doping panel last Saturday.

Warne said the earlier fluid tablet was taken for the sake of appearance and before his shoulder injury, proving he was not a drug cheat who had taken diuretics to mask other drugs to speed his recovery.

"I was (drug) tested on December 12 which was negative. This was before the injury - I was injured on the 15th," Warne told Channel Nine's A Current Affair.

"It has since came up at the hearing that there were small traces of the same ingredients that I was tested positive for in January.

"I admitted to the hearing that I had taken a tablet in early December.

"I was doing a lot of wine promotions. I'd had a couple too many bottles of wine and had a few late nights.

"I took a fluid tablet then - that was the first time she (Mum) gave it to me. It was to get rid of a double chin.

"The December 12 test showed small traces of the same thing. That was before my operation - that proves I didn't take the fluid tablet to mask anything."
