Johnson and Johnson‘s McNeil Healthcare Unit, manufacturers of Tylenol are in trouble again after consumers began complaining that their bottles of adult Tylenol smelt musty. The musty smell is chemical preservative called 2,4,6-tribromoanisole used in crates of wooden pellets that the medication is packed in during transit.

Johnson and Johnson are already facing investigation by the FDA for breaches in health and safety and their factory at Fort Washington, Pa, is closed while the investigation is carried out.

The medicine tastes and smells foul, but the manufacturers say they don’t think there is a risk of harm. They have recalled the offending bottles as a precaution.

Just a few months ago they recalled lots of Tylenol for arthritis pain for the same reason. That product had caused stomach pain, nausea, vomiting, and diarrhea in consumers who took it. The company say that these effects are only temporary and not serious but no one has ever studied the effects of ingesting the chemical.

If you have bought or taken the affected products, you can telephone Tylenol’s customer care team on:

1-888-222-6036

Concentrated Tylenol Infant’s Drops (grapes, cherry flavor and hospital only variety, various sizes).
