Zinc Cold Remedy Can Cause Smell Loss

Wednesday, 21 Jul 2010 08:40 AM


A popular zinc-based homeopathic remedy for the common cold that is sold over the counter is not only ineffective in preventing or reducing the duration of the common cold, but can cause users to lose their sense of smell, a study in Archives of Otolaryngology warned.

The authors of the study sounded the warning about zinc nasal cold remedies after evaluating 25 patients and analyzing reports of clinical, biological, and experimental data.

Only one of the studies analyzed showed that zinc therapies reduce the severity of a cold — but it was funded by the makers of the medicine used in the study.

"In addition to concerns regarding the efficacy of intranasal zinc therapy, increasing evidence indicates that this medication may be linked to severe, potentially permanent hyposmia (reduced sense of smell) and anosmia (loss of smell)," the study says.

In the light of their findings, the authors urged the U.S. Food and Drug Administration (FDA) to more strictly regulate zinc cold therapies and other homeopathic remedies.

"Only homeopathic drugs offered for treatment of 'serious disease conditions' must be dispensed by a licensed practitioner," the study said.

Homeopathic products that treat less serious illness, such as the common cold, can be sold over the counter and are exempt from "the rigorous premarket approval process that allopathic medications must go through before entering the market," the authors of the study said.
