Those remaining medicines which are at risk of withdrawal will be covered by the new schemes, allowing them to be supplied from Great Britain.
Northern Ireland Agriculture Minister Andrew Muir said he was “disappointed” that concerns he had raised with the government had not been addressed.
“I’m worried that the UK government are overselling this and I’ll be seeking another meeting with the UK government about this,” he added.
“I’m glad to see the problem is much reduced compared to what we were seeing last year.
“But it’s important when we’re bringing forward proposals that we don’t oversell them.”
In a statement, the government said that out of about 3,000 products licensed for supply in Northern Ireland, its “current expectation is that there will be very limited disruption, with fewer than 20 products due to face discontinuation that we consider are likely to result in significant adverse impacts if not addressed”.
The main measure to address those impacts is the Veterinary Medicine Internal Market Scheme under which vets can order medicines from GB if it is impractical to get them from the EU.
Vets can also hold stocks of products made available under that scheme rather than having to order them for each patient.
