Diclofenac is available as both a generic medication and under various brand names.
What brand names is diclofenac sold under?
Diclofenac is marketed under several brand names, including Voltaren, Cataflam, Cambia, Zorvolex, and others [1][2]. These brand names often indicate specific formulations or strengths of diclofenac.
Is diclofenac a prescription drug or over-the-counter?

Lower-strength topical formulations are frequently available OTC for minor pain relief, while higher-strength oral versions typically require a prescription.

Diclofenac potassium, found in brands like Cataflam, is designed for faster absorption compared to diclofenac sodium, which is common in many other diclofenac products [4].
