Consumers are being warned to stop using Tylenol Arthritis Pain Caplets if the bottle has a big red easy-to-open cap. The manufacturer, Johnson and Johnson has expanded a recall that started in November. Some lots have an unusual moldy or mildewy smell. Some people report nausea, vomiting, stomachache and diarrhea after taking these pills. The FDA suspects that the odor originates in the wooden pallets used to ship packaging materials.
