Meloxicam vs. Diclofenac
See how Meloxicam and Diclofenac compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Both meloxicam and diclofenac are NSAIDs with boxed warnings for cardiovascular and gastrointestinal risks, so neither is a lower-risk default choice.
Meloxicam's once-daily dosing may be easier to stick with than diclofenac's two-to-three-times-daily schedule.
Diclofenac covers more FDA-approved uses out of the box, including acute pain and menstrual cramps, while meloxicam is only approved for arthritis conditions.
Meloxicam vs. Diclofenac Drug Summary
Meloxicam
Meloxicam is an NSAID used to relieve pain and inflammation from osteoarthritis, rheumatoid arthritis, and juvenile rheumatoid arthritis. It's taken as a tablet, capsule, or liquid, typically once a day. An IV form is also available for short-term pain management in hospitals.
Diclofenac
Diclofenac is an NSAID used to relieve pain and inflammation from osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute pain like menstrual cramps. It's taken as a delayed-release tablet, usually two to three times a day. A topical gel version is also available over the counter for localized pain.

Meloxicam vs. Diclofenac Indications
Meloxicam
Meloxicam is FDA-approved for osteoarthritis, rheumatoid arthritis, and juvenile rheumatoid arthritis in children 2 and older. It's also used off-label for ankylosing spondylitis and general musculoskeletal pain, though these aren't FDA-approved uses.
Osteoarthritis in adults
Rheumatoid arthritis in adults
Juvenile rheumatoid arthritis in children 2+
Ankylosing spondylitis (off-label)
General musculoskeletal pain (off-label)
Diclofenac
Diclofenac is FDA-approved for osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, acute pain, and primary dysmenorrhea. It covers a broader range of approved conditions than meloxicam, including acute pain relief and menstrual cramps.

Rheumatoid arthritis
Ankylosing spondylitis
Mild to moderate acute pain

Meloxicam vs. Diclofenac Pros and Cons
Meloxicam
Meloxicam carries the same boxed warnings for cardiovascular and GI risk as most NSAIDs, but its once-daily dosing and pediatric approval set it apart. It's not approved for acute pain or dysmenorrhea, so it's mainly used for ongoing arthritis management.
Pros
Once-daily dosing for most adults
Approved for children 2+ with juvenile RA
Available in tablet, ODT, capsule, IV, and liquid forms
Lower reported GI side effect rates on label
Cons
Not approved for acute pain or menstrual cramps
No over-the-counter topical formulation
Newer to market (approved in 2000)
Diclofenac
Diclofenac shares NSAID class risks but is approved for a wider set of acute and chronic pain conditions than meloxicam. Its multiple daily dosing and higher reported GI symptom rate are tradeoffs for that broader approval.
Pros
Approved for acute pain and menstrual cramps
Longer market history (approved since 1988)
Available as OTC topical gel for localized pain
Available in ophthalmic and injectable forms too
Cons
Requires dosing two to three times daily
Higher reported GI symptom rate (about 20%)
Not approved for pediatric use
