Voltaren Joint Pain Extra Strength (ES) is a topical nonsteroidal anti-inflammatory drug (NSAID) gel that contains diclofenac diethylamine. It helps relieve inflammation and pain from common joint and muscle injuries. In the U.S., the most common marketed form is Voltaren Arthritis Pain Gel (diclofenac sodium topical gel, 1%).
1% strength is approved over the counter (OTC) for temporary relief of arthritis-related joint pain. Voltaren Joint Pain ES 2.32% is a higher-strength topical diclofenac gel marketed in Canada and other countries. Its prescription status varies by country (e.g., it’s prescription-only in Canada), but in the U.S., the commonly sold Voltaren topical gel for joint pain relief is OTC and does not require a prescription. Consult your doctor or pharmacist before using Voltaren gel for knee pain or joint pain.

Voltaren Joint Pain Extra Strength is formulated to relieve pain from acute, localized, minor muscle or joint injuries. It may help with:
Voltaren Joint Pain ES works directly where the pain occurs. Its active NSAID ingredient, diclofenac diethylamine, penetrates through the skin to the inflamed tissues. Voltaren diclofenac gel temporarily blocks the production of pain-signaling chemicals (prostaglandins) that contribute to joint pain and swelling. Since it’s applied to the skin, much less of the drug enters the bloodstream than with oral NSAIDs, which may lessen systemic risks for some people.
According to the PubMed review “Effectiveness and safety of topical vs. oral NSAIDs,” topical NSAIDs such as Voltaren Joint Pain ES may be as effective as oral NSAIDs for many joint and muscle conditions. Topical and oral NSAIDs may provide similar localized pain relief for certain musculoskeletal conditions, with lower systemic risk, but evidence varies by condition. Additionally, their safety profiles differ because of how much medication enters the bloodstream.

|---|---|---|
| Pain relief | Works about as well as oral NSAIDs for localized joint and muscle pain | Works well for pain and inflammation |
| Where it works | Mainly at the spot where you apply it | Works throughout the whole body |
| Amount absorbed into the blood | Very low | Much higher |
| Stomach side effects | Much lower risk | Higher risk of stomach upset, ulcers, or bleeding |
| Heart and kidney risk | Lower overall risk | Higher risk, especially with long-term use |
| Skin reactions | More likely (redness, itching at the site) | Rare |
| Best choice for | Pain in one or two joints (knee, hand, ankle) | Pain affecting many joints or the whole body |
