What is Acetaminophen and Hydrocodone

Acetaminophen and hydrocodone are used together to treat moderate to severe pain due to cancer, dental procedures, headache, back pain, and arthralgias and myalgias.

Acetaminophen is a non-salicylate analgesic with similar analgesic potency to NSAIDs, and hydrocodone is an oral semisynthetic opiate agonist derived from the opioid alkaloid, thebaine.

The combination of acetaminophen and hydrocodone produces additive analgesia as compared to the same doses of either agent alone. Combinations containing higher doses of one or both components give progressively increasing analgesia.

However, dosage escalation of this combination is limited by the maximum dose and ‘ceiling effect’ of acetaminophen. The combination of acetaminophen and opioid analgesics may achieve a ‘dose-sparing’ effect such that lower doses of the both agents produce pain relief with fewer side effects.

In a comparison of emergency room patients treated with either hydrocodone or codeine both in combination with acetaminophen, the hydrocodone combination resulted in less treatment failures and fewer central nervous system side effects than the codeine combination.

Acetaminophen and hydrocodone combinations are available as tablets, capsules, and liquid dosage forms.
