Pharmaceutical giant Johnson & Johnson will be forced to issue graphic warnings about the health risks associated with its pelvic mesh products, as the Federal Court cracks down on the company and its affiliates following a multimillion-dollar class action.

On Friday, Justice Anna Katzmann read out a detailed warning that the company and its affiliates in Switzerland and America, Ethicon Sarl and Ethicon Inc, must provide in patient information leaflets and promotional material if it wishes to continue selling a number of "prolene" polypropylene pelvic mesh products in Australia after March 20.

It follows her decision on Tuesday awarding $2.6 million in damages to three women at the centre of a class action against the companies, in the first wave of compensation.

The mesh products were designed to be used in cases of stress urinary incontinence or pelvic organ prolapse but the court heard the devices had caused a range of serious complications including chronic pain, infections and damage to surrounding organs.
