What is a white oblong pill with AZ 328 inscribed on one side?

Not Medical Advice: The pill imprint "AZ 328" belongs to a generic form of Tylenol (Extra Strength Pain Relief, Acetaminophen 500 mg).

Acetaminophen is used to treat many conditions such as headache, muscle aches, arthritis, backache, toothaches, colds, and fevers. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines as well.

The FDA patent for acetaminophen was issued in 1951, but it was not until two years later that the Sterling-Winthrop company began selling this drug. In 1955, the brand Tylenol was release by McNeil Laboratories.

In drug news, a federal judge this past week reversed a contentious Food and Drug Administration ruling and ordered the agency to make the "morning-after pill" available without a prescription to all females of reproductive age, including those younger than age 17.
