The management's warning comes after the company began withdrawing monoguet syringes due to concerns about incompatibility between its parts.

Monogekt syringes are used to enter or withdraw fluid from the body, while patient-controlled pain management pumps are used to treat different types of pain by intravenous drug transfer.

In June, the company began selling new monoject syringes that have different dimensions compared to the company's previous versions known as Covidien.

The administration said today that Covidin syringes could be used and that it would work with the company to further assess the problem that emerged in the new syringes.
