Frequently asked questions
Is diclofenac stronger than ibuprofen?
It is a potent NSAID often used for more severe inflammatory pain, but stronger effect can mean higher risk. Your doctor weighs benefit against your heart and stomach risk.
Can I use diclofenac gel instead of tablets?
For localised joint or muscle pain, the gel gives relief with far less effect on the stomach and is often preferred.
