How it works

From the US prescribing label for the same active substance (Acetaminophen). It describes the substance, not this exact product.

The precise mechanism of the analgesic and antipyretic properties of acetaminophen is not established but is thought to primarily involve central actions.

Peak level after15 min
How the body breaks it down

With therapeutic doses, NAPQI undergoes rapid conjugation with glutathione and is then further metabolized to form cysteine and mercapturic acid conjugates.

How it leaves the body

Acetaminophen metabolites are mainly excreted in the urine.
