Some natural iron supplements are under recall because the bottle may contain a completely different substance and cause serious side effects.

The Food and Drug Administration says the recall involves rugby natural iron supplement ferrous sulfate.

But instead of ferrous sulfate, which is a type of iron, the bottles may actually contain meclizine.

Meclizine is a drug used to treat nausea, vomiting and dizziness, and is commonly used to prevent motion sickness.

Here’s a look at the dangerous side effects it can cause:
Taking Meclizine HCl 25 mg as Ferrous Sulfate 325 mg may cause serious side effects to those who consume alcohol or other sedatives, those with a pre-existing CNS disorder, those with imprinted kidney or liver function, the elderly, nursing infants of lactating mothers who received the drug and newborns of mothers who received the drug immediately before childbirth.
