The Drug Administration of Vietnam on May 4 asked all city and provincial health departments to recall four US manufactured drugs for children, including Tylenol, Motrin, Zyrtec and Benadryl in Vietnam’s market.

The withdrawal was made after the United States and Canada’a Food and Drug administrations reported that the products might not meet required quality standards.

A representative from the administration said that the four drugs were not granted licences in the local market./.
