Health Minister Victor Boudreau introduced amendments Tuesday that would eliminate the requirement that would have taken effect April 1.
The Liberal government says it will also conduct a review of the provincial drug plan in an effort to ensure costs are reasonable.
Boudreau says he will create two new premiums for low-income earners in the plan.
He says the drug plan will remain voluntary until the review is completed and it's not the government intention to introduce any mandatory contributions from employers.
The amended plan would carry on as a premium and co-pay based model that varies by income.
