Thomas said there was “increasing peril” in the sector that he has worked in for 40 years.
He said it feels like Wales is “heading off a cliff” unless serious changes are made.
“We’re having to buy drugs at a higher cost than we will actually be reimbursed for from the drug tariff,” he said.
“That gives us little or no margin to pay your staff or to or to pay for deliveries.”
He said pharmacies are also becoming busier because GPs and surgeries are directing patients their way to ease pressure on the health service.
“It is a great initiative, but it means we’re busier all the time, which means we’re more staff intensive, and we’re not able to make the money,” he added.
“We want to do the services and we want to look after our patients.
“But the current structure of how we’re reimbursed has not changed.”
Thomas admits he is simply trying to “keep the show on the road” at the moment but says this “cannot go on”.
“Last September, I took out a short term loan of £70,000 just to to get us through the month,” he said.
“I’ve run this place for more than 20 years and I owe the bank more than double what I paid for the original pharmacy.”
