The Australian Medical Association (AMA) says there needs to be closer analysis of the use of an ADHD drug that has been linked to an increased risk of suicide.

The October update from the Therapeutic Goods Administration (TGA) says up to July this year, there have been 74 reports of psychiatric disorders associated with the drug Strattera.

The TGA also received reports of two attempted suicides in children and adolescents, while one child did commit suicide.

The AMA's president Steve Hambleton says he is concerned that 3-5 per cent of the population has been prescribed the drug.

"There's certainly variations between the prescription rates, and there's a lot of prescribing in NSW, and we do need to analyse that more," he said.

"Does that mean we should be prescribing more in other states, or does it mean we should be looking at alternative methods in NSW?

"It's always worth looking at that variation they're describing so we can get a better outcome."
