Oxford University researchers suggest that selling paracetamol and other painkillers in smaller pack sizes has slashed suicide rates, which has been reported in the British Medical Journal.
Almost 25% fewer people took fatal aspirin and paracetamol overdoses in the three years after 1998 than before.
Sue Simkin, senior researcher at the Centre for Suicide Research at the University of Oxford, said: "Legislation restricting pack sizes of analgesics in the United Kingdom has been beneficial.
"A further reduction in pack sizes could prevent more deaths”.
