⚠️Safety advisory – Safety concerns over imported counterfeit melatonin products⚠️
We are issuing an updated safety advisory regarding imported counterfeit unregistered melatonin products.
Laboratory testing of several imported unregistered melatonin products has confirmed they are counterfeit under the Therapeutic Goods Act 1989.
The results indicate significant discrepancies in the actual melatonin content compared to the labelled amounts. One product contained more than 400% of the labelled content and another containing no melatonin at all.
This variability in melatonin content raises serious safety concerns for consumers, including the risk of accidental overdose and hospitalisation, especially in children.
Melatonin is a prescription-only medicine in Australia, except in specific circumstances for adults.
Parents are strongly encouraged to consult their child’s treating medical practitioner regarding the use of melatonin, especially for children with seizure disorders as it may increase seizure frequency.
Melatonin products taken without appropriate medical oversight can cause serious side effects including accidental overdose and hospitalisation, especially in children.
