Who might it suit?

Not for: People with NSAID contraindications; not a first-line treatment for a deep hip joint.

Limits and important cautions
A deep hip joint is less suited to topical treatment. Skin reactions and NSAID contraindications still matter; check other medicines with your clinician.
