There are two problems with Voltaren Gel, that I have seen:
- First: Many insurance companies will not pay for Voltaren Gel. It is quite expensive, depending on the state where you live, but can cost $50-100 per tube of gel. Often you can appeal to your insurance company, but this does not always work. Furthermore, they usually require that you try other standard arthritis treatments for at least several months, before they will pay for the medication.
- Second: The studies show only moderate improvement in symptoms. A recent study of patients with knee arthritis found slight differences in patients who used Voltaren Gel versus a placebo treatment. It is hard to recommend a treatment, that may cost a lot for the patient, when the expected benefit is modest at best.
