A third of people with long term health conditions have not collected a prescription due to the cost, it has been warned.
Labour's Tonia Antoniazzi warned that fears over the price of medication - at £9.35 per item - are leading to many either skipping or reducing their doses.
The findings come from research from the Prescription Charges Coalition, a group of 50 organisations calling on the government to scrap the prescription charges for people with long term conditions in England.
