Concerta, the generic drug sold under the brand name Concerta Side Effects, is linked to a number of serious side-effects including kidney damage and liver failure, according to a report published on Thursday.
It is unclear whether the drug is safe and effective, and its makers have yet to respond to the news.
A spokesperson for Concerta said the company was working to understand the issue.
“We take safety and efficacy very seriously, and we are taking all of the appropriate steps to ensure this is not the case.
We are aware of the concern raised by the media, and our team is currently working with Health and Safety and the Australian Government to provide answers to the issues,” the spokesperson said.
In February, the New South Wales Health Department published a study of concerta pills that found the drug caused severe and serious side effect in some users.
The report warned that people who took Concerta pills should not use the drugs recreationally.
“The risk of serious adverse effects is particularly high in people taking Concerta for more than four hours daily and in those who take the pill for longer than one week,” the report said.
Concerta is the second-most prescribed prescription painkiller in Australia, behind only oxycodone.
A report by health experts found the prescription drug is associated with significant harms, including heart attacks, strokes, liver damage, depression and suicide.
