Two medicines, side by side

Methadone vs oxycodone

Methadone and oxycodone are both labeled for pain. Drugs@FDA records approvals of methadone since 1947 and of oxycodone since 1998. Pharmacies paid $0.177 per methadone HCl 10 mg tablet and $0.0884 per oxycodone HCl (ir) 5 mg tablet (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. How each works, in its label's words: Methadone, “Methadone hydrochloride is a mu-agonist; a synthetic opioid with multiple actions qualitatively similar to those of morphine, the most prominent of which involves the central nervous system and …”; Oxycodone, “Oxycodone is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses.”

Check it at the source: the methadone FDA label on DailyMed (effective December 8, 2025); the oxycodone FDA label on DailyMed (effective May 6, 2026).
