Celecoxib vs Dutasteride: side-by-side comparison
Celecoxib (COX-2 selective NSAID) and Dutasteride (Dual 5α-reductase inhibitor (type 1 and type 2)) belong to different therapeutic classes and are rarely substitutes for each other. The comparison is useful when a single patient is weighing both options for adjacent or overlapping needs.

What they share
Celecoxib and Dutasteride share the common regulatory framework for prescription active ingredients, bioequivalence standards for generics, and pharmacist oversight. Beyond that, points in common are limited.
Key differences
Celecoxib acts by a different mechanism than Dutasteride, with indications that barely overlap. Comparing the two is useful when a clinician has mentioned both in the same context or the patient wants to understand why one was prescribed instead of the other.
Mechanisms compared
Celecoxib: Celecoxib selectively inhibits cyclooxygenase-2 (COX-2), the enzyme isoform induced at sites of inflammation, which produces the prostaglandins responsible for pain, fever and inflammation. Dutasteride: Dutasteride irreversibly inhibits both isoenzymes of 5α-reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT).
Indications compared
Celecoxib: Celecoxib is approved in adults for the treatment of osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, acute pain in adults and primary dysmenorrhoea. Dutasteride: Dutasteride is approved for symptomatic benign prostatic hyperplasia, alone or in combination with tamsulosin (Combodart/Jalyn) for greater symptom relief.
Safety profile
Celecoxib: Common adverse effects include gastrointestinal symptoms (less frequent than with traditional NSAIDs), peripheral oedema, hypertension and headache. Dutasteride: Common adverse effects include sexual side effects (decreased libido, erectile dysfunction, ejaculatory disorders), gynaecomastia and breast tenderness.
Frequently asked questions
Is Celecoxib better than Dutasteride? ▾
Celecoxib and Dutasteride are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Celecoxib and Dutasteride be combined? ▾
Whether they can be combined depends on the indications and the interaction profile of each. If both are in a single prescription, the prescriber has weighed it; in self-medication they should never be combined.
Do they have the same side-effect profile? ▾
No — they belong to different classes and have distinct side-effect profiles. Each has its own prescribing information.
