Is 10 500 stronger than 10 500 of hydrocodone?

A Hydrocodone pill usually has mixed with it Acetaminophen (chemical name is Paracetamol outside U.S., U.S. brand name Tylenol). Hydrocodone is a strong narcotic (Schedule II in U.S.) that suppressed the entire nervous system and also acts as a cough suppressant. Acetaminophen is included as a milder pain reliever (analgesic) to provide different effects. Hydrocodone is not sold alone in the U.S.

The Hydrocodone/Acetaminphen pill (aka Hydrocodone/APAP) is described with two numbers. The first number, for example 5 mg, gives the amount (strength) of the Hydrocodone. It is followed by another number, for example 500 mg, that gives the amount of the Acetaminophen.

So your question asked if Hydrocodone pills can include more than 500 mg of Acetaminophen?

The answer is YES.

Typically the pill comes in doses of 5mg/500mg, 7.5mg/750mg, and even 10mg/1000mg. However pharmaceutical manufacturers can formulate pills in other combinations to increase the drug's effect and/or reduce health risks.
