Adeeva Nutritionals is recalling one lot of its digestive aid Flora Essentials due to possible contamination with an antibiotic that may pose serious health risks, Health Canada said today.

Chloramphenicol is associated with a rare risk of aplastic anemia, a serious blood disorder that can be fatal. The reaction is unpredictable and not related to a specific dose of the antibiotic, Health Canada said.

Affected products

Flora Essentials (NPN 80039819) Lot #10342

Side-effects linked to the antibiotic, which is available through prescription and should be used only under medical supervision in adults and children, include allergic reactions in those with a sensitivity to the medication and effects on the bone marrow leading to decreased blood cells.

The drug should not be taken by pregnant or lactating women.

Adeeva, of Woodbridge, Ont., is recalling Lot 10342 of Flora Essentials, and says consumers who have used the natural health product should immediately consult their health-care practitioner.

The Adeeva website lists the product as "temporarily out of stock."

Neither the company nor Health Canada has received reports of adverse reactions associated with the product.

To return the product, consumers should call Adeeva Nutritionals at 1-888-251-1010, ext. 1014.
