What they share
Meloxicam and Loratadine 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
Meloxicam acts by a different mechanism than Loratadine, 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
Meloxicam: Meloxicam inhibits cyclooxygenase enzymes with a preference for COX-2 at low therapeutic doses. Loratadine: Loratadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine released during allergic reactions.
Indications compared
Meloxicam: Meloxicam is approved in adults for the symptomatic treatment of osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. Loratadine: Loratadine is approved in adults and children for the treatment of allergic rhinitis, including seasonal and perennial forms, and chronic idiopathic urticaria.
Safety profile
Meloxicam: Common adverse effects include gastrointestinal symptoms, peripheral oedema, hypertension and headache. Loratadine: Loratadine is generally very well tolerated.
Frequently asked questions
Is Meloxicam better than Loratadine? ▾
Meloxicam and Loratadine are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Meloxicam and Loratadine 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.
