Summary. If you visit the Vicks product page for their Vapoinhaler, you’ll find that product warnings are conspicuously absent other than the advice to call a poison control center if the contents are swallowed.
If you consult greater medical authorities on healthcare such as the WebMD page on this product, you’ll find a product warning is missing from there as well. The only information provided is, “Consult your pharmacist.”
Only the Walgreens Pharmacy product page for the Vicks VapoInhaler contains the essential product warnings that consumers should be informed about:
