Wales is marking 18 years since becoming the first UK nation to abolish prescription charges.
Since 2007, Welsh pharmacies have dispensed more than one billion items.
The charges were abolished as costs were preventing a third of people from getting their prescribed medication. People with chronic conditions had reported cutting back on food and bills to afford medication, leading to worsening health, increased GP visits and hospital admissions.
The data shows that more than 313,000 items are prescribed by GPs and dispensed by pharmacies free of charge every working day.
Cabinet secretary for health and social care, Jeremy Miles said: "Free prescriptions are one of Wales' greatest healthcare achievements to date.
"I'm proud that we led the UK in taking this bold step, ensuring everyone, regardless of their financial circumstances, can get the medication they need.
"Over 18 years, this policy has transformed so many people’s lives, helped thousands manage their conditions effectively, and prevented unnecessary hospital admissions. Healthcare should be based on clinical need, and this is what free prescriptions are about.
"As we look to the future, we are committed to this principle, it’s served the people of Wales so well."
