OTTAWA - Health Canada says it is banning imports of some medications and drug ingredients produced in India due to concerns about quality.

The agency took the action against Apotex Pharmachem India, Apotex Research Private Ltd. and IPCA Laboratories.

It says it has "significant concerns" with the manner in which research data is collected and reported, raising serious doubts about quality and safety.

The agency says until it is satisfied that production processes at the three sites meet international standards, it will keep these products off the market.

Health Canada stresses there are "no specific safety issues" with products now on the market from those companies, nor has a recall been requested.

It adds that consumers should not make any change to their medication without first consulting with a healthcare professional.
