What is Voltaren? The Drug Diclofenac
Yes, Voltaren is a drug. It is the brand name for diclofenac sodium, a nonsteroidal anti-inflammatory drug (NSAID). Diclofenac belongs to the same class of drugs as ibuprofen and naproxen. It is used to treat pain and inflammation caused by various conditions. While a 1% topical gel for osteoarthritis pain is available over-the-counter (OTC), other formulations require a prescription.
How Voltaren Works to Relieve Pain
Voltaren's active ingredient, diclofenac, reduces pain and inflammation by blocking cyclooxygenase (COX) enzymes, particularly COX-1 and COX-2. These enzymes produce prostaglandins, chemicals that cause pain and inflammation. By inhibiting these enzymes, diclofenac decreases prostaglandin production, thus reducing pain, swelling, and tenderness.
Its action differs based on the form:
- Topical Gel: Applied to the skin, the gel allows diclofenac to target local tissues and inflamed joints with less systemic absorption than oral forms.
- Oral Tablets: Taken by mouth, diclofenac is absorbed into the bloodstream for broader, systemic pain and inflammation relief.
The Different Forms of Voltaren
Voltaren is available in several forms containing diclofenac:
- Voltaren Arthritis Pain Gel (1%): OTC for osteoarthritis joint pain.
- Prescription Gels and Solutions: Stronger topical options, like the 3% gel, are prescription only.
- Oral Tablets: Prescription-only for systemic relief.
- Ophthalmic Eye Drops: Used for certain eye conditions.

Important Safety Information and Warnings
Voltaren, like other NSAIDs, carries an FDA boxed warning due to potential serious risks, though the risk is lower with the topical gel. These risks include increased chances of heart attack and stroke, especially with long-term use or high doses. There's also a risk of severe gastrointestinal issues like bleeding or ulcers. Voltaren should not be used before or after heart bypass surgery, and combining it with other NSAIDs is generally not advised due to increased side effect risk. Allergic reactions are possible, especially for those sensitive to aspirin or other NSAIDs. Consult the official FDA guidance for comprehensive information.
Conclusion
Voltaren is a drug, specifically an NSAID containing diclofenac, used to treat pain and inflammation. While the 1% topical gel is available OTC for osteoarthritis pain, prescription forms are also available. Understanding its mechanism, different forms, and potential side effects, including the boxed warnings for cardiovascular and gastrointestinal risks, is vital for safe use. Always consult a healthcare provider to determine if Voltaren is appropriate for your condition.
