That's a 16 per cent decrease on 2019.
There were nearly 7,800 reports of people having adverse reactions to medicines last year.
137 patients died afterwards - but many had underlying illnesses.
Eoghan Murphy reports:
"The Health Products Regulatory Authority got 7,752 reports of suspected adverse reactions, linked to human medicines, last year.
That's a 16 per cent decrease on 2019.
Over 3,400 were associated with drugs that are used to treat cancer.
Dr Martin Daly, a former president of the Irish Medical Organisation, says there's an obvious reason for this.
Of the other adverse reactions reported, 578 were linked to psychiatric drugs that are used to calm people down, while 427 were related to vaccines.
137 people died after having suspected bad reactions to medicines last year.
Many of the patients had underlying illnesses, which may have also have contributed to their deaths.
There were 17 reports of people having serious adverse reactions and events linked to organ donation or transplants. "
