The latest recall includes more than 34,000 bottles of Tylenol 8-Hour Extended Release Caplets.
The odor is thought to be caused by a chemical used to treat wooden pallets on which the bottles are stored and shipped.
Consumers who purchased products from the latest recalled lot should stop using them.
The company also expanded a Jan. 14 recall of various Tylenol, Benadryl, Sudafed and Rolaids packages distributed to wholesalers across the U.S. The latest action adds an additional 717,000 packets to the 47 million recalled in January.
