More drug stores are pulling a popular heartburn medication over cancer concerns.

Major pharmacy chains like CVS, Walgreens and Rite Aid have decided to pull Zantac from its shelves.

It comes after a FDA report filed last month found Zantac, and its generic form Ranitidine, contain a "probable human carcinogen" known as NDMA.

The concern centers on the tablet version of the drug, and doctors say that comes as a relief to many parents, whose children may be using the liquid form.

Dr. John Zaso says adults who have been prescribed Zantac should consult their doctor, and those who purchased it over the counter and only use it from time to time should consider trying another brand.
