The U.S. Food and Drug Administration on Tuesday announced that millions of needles have been voluntarily recalled. These needles are used in ports implanted under the skin of chronically ill patients.

Manufactured by Nipro Medical Corp. in Japan and distributed by Exelint International Corp., headquartered in Los Angeles, California, about two million Huber needles are affected.

Huber needles are used by clinics or at home to draw blood or to inject medicine. Exelint's needles cored or cut slivers of silicone, raises the chances of silicone entering the veins, that results in damaging the port itself or harming the surrounding tissue.

The FDA said that there have been reports of leakage. FDA said that everyone who is using the products should put a stop immediately and return any unused needles to Exelint.

Exelint was  not available for any immediate public comment.
