Two medicines, side by side

Hydromorphone vs tramadol

Hydromorphone and tramadol are both labeled for pain. Drugs@FDA records approvals of hydromorphone since 1984 and of tramadol since 1995. Pharmacies paid $0.219 per hydromorphone 4 mg tablet and $0.0248 per tramadol HCl 50 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: Hydromorphone, “Hydromorphone 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.”; Tramadol, “Tramadol hydrochloride extended-release tablet contains tramadol, an opioid agonist and an inhibitor of reuptake of norepinephrine and serotonin.”

Check it at the source: the hydromorphone FDA label on DailyMed (effective May 14, 2026); the tramadol FDA label on DailyMed (effective March 5, 2026).
