A pharmaceutical company in northeast China has been ordered to recall some of its products that were improperly labelled, the State Food and Drug Administration (SFDA) announced Thursday.

The Harbin Yida Pharmaceutical Co.,Ltd in Heilongjiang Province was told to recall arsenious acid and sodium chloride injection produced since the beginning of 2009.

The SFDA did not detail the quantities of the injection to be recalled.

The provincial drug watchdog on Wednesday found that the volume of the injection was not in line with the label on some samples.

"The use of any drug must fully comply with requirements," a senior official of the SFDA said. "Safety cannot be guaranteed if the marked specification doesn't match the actual amount."

The injection is mainly used to treat promyelocytic leukemia and malign lymphomas and is conducive to enhancing the effectiveness of radiotherapy.

No cases of adverse reactions to the injection had been reported, said the official.
