Half of the $4 billion in fraudulent health care claims recouped by the government last year came from big pharma. An HHS report cites fraud by drug and device makers, with Allergan's $600 million fine and settlement for off-label Botox marketing topping the list. Allergan is followed by Novartis Pharmaceuticals, with $422.5 million in fines; AstraZeneca, $520 million; Forest Laboratories and Forest Pharmaceuticals, $313 million; and Teva, $100 million.
