Phenacetin is a pain-relieving and fever-reducing drug, widely used from its introduction in 1887 until banned in the US by the FDA in 1983. Its use has declined because of its adverse effects, which include increased risk of certain cancers and kidney damage.
It is metabolized into paracetamol, which replaced it in some over-the-counter medications following the ban on phenacetin.
Phenacetin was widely used until the third quarter of the twentieth century, often in the form of an "A.P.C." or aspirin-phenacetin-caffeine compound analgesic, as a remedy for fever and pain. An early formulation (1919) was Vincent's APC in Australia. However the U.S.
Food and Drug Administration ordered the withdrawal of drugs containing phenacetin in November 1983, owing to its carcinogenic and kidney-damaging properties (Federal Register of October 5, 1983 (48 FR 45466)

The antipyretic effect is stronger than the analgesic effect. The effect of intensity is slow and long lasting, as aspirin, with low toxicity. research shows:
This product and its metabolites have antipyretic effects on acetaminophen. Because enzyme inhibitors do not convert phenylacetic acetate into paracetamol, there is still a significant antipyretic effect, so the antipyretic effect of the post-production line does not translate into paracetamol.
Mild phenacetin acetate analgesia usually lasts 3 to 4 hours; and synergistic, co-administration can improve the analgesic effect.
