WASHINGTON — The Food and Drug Administration is asking consumers to check any bottles of a prescription allergy and cold medicine syrup called Promethazine VC Plain to make sure it does not contain a thick white lotion instead of the normal orange-yellow syrup.
The agency said Friday that the white lotion may be lindane, a medicine for parasitic mites known as scabies. Lindane could cause severe convulsions if taken by children, the FDA said.
