Two medicines, side by side
Levorphanol vs oxycodone
Levorphanol and oxycodone are both labeled for pain. Drugs@FDA records approvals of levorphanol since 1953 and of oxycodone since 1998. Pharmacies paid $10.65 per levorphanol 2 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.
