Photographed another Elvis Presley item today. Prescription antibiotics (Tetracycline) from May 8, 1974. Several of the pills have mold growing on them. A quick google search pulls up this: Tetracycline, is used to treat bacterial infections, including pneumonia and other respiratory tract infections; acne; infections of skin, genital and urinary systems; and the infection that causes stomach ulcers.
