Two medicines, side by side

Naproxen vs morphine

Naproxen and morphine are both labeled for pain. Drugs@FDA records approvals of naproxen since 1976 and of morphine since 1984. Pharmacies paid $0.0565 per naproxen 500 mg tablet and $0.226 per morphine sulfate ir 15 mg tablet (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. In FDA's classes, naproxen is a nonsteroidal anti-inflammatory drug and morphine an opioid agonist.

Check it at the source: the naproxen FDA label on DailyMed (effective March 12, 2026); the morphine FDA label on DailyMed (effective July 13, 2026).

Pharmacologic classNonsteroidal Anti-inflammatory DrugOpioid Agonist
How it works (label)n/aMorphine is a full opioid agonist is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of morphine is analgesia.
Half-life (label)n/aExcretion The elimination of morphine occurs primarily as renal excretion of M3G and its effective half-life after intravenous administration is normally 2 to 4 hours.
