From the Guidelines
Voltaren gel (diclofenac sodium 1%) should be applied to the affected area 4 times daily in amounts of 2-4 grams per application, not exceeding 16 grams total per day. When considering the treatment of degenerative arthritis, the North of England Non-Steroidal Anti-Inflammatory Drug Guideline Development Group recommends alternative drugs such as diclofenac if initial treatments fail 1. Although the provided study does not specify the dose and frequency of Voltaren gel, based on general medical knowledge and clinical practice guidelines, the recommended application is typically 2-4 grams per application, 4 times daily. For most joints, a 2-gram dose (about the size of a quarter) is sufficient to cover a 4x4 inch area, while larger joints like the knee may require a 4-gram dose. It is essential to gently rub the gel into the skin until it disappears and wash hands thoroughly after application, unless treating the hands. Treatment duration should generally not exceed 7 days for sprains or 14 days for arthritis without medical supervision. The topical formulation of Voltaren allows the medication to penetrate directly to the affected area, minimizing systemic absorption and resulting in fewer side effects compared to oral NSAIDs. Key considerations include avoiding application to broken or irritated skin and not covering treated areas with bandages or wraps that don't breathe. In clinical practice, it is crucial to weigh the benefits and risks of using Voltaren gel, considering the potential for side effects and interactions with other medications. Given the lack of specific dosing information in the provided study, the recommended dose and frequency are based on general clinical guidelines and the properties of the medication itself. The goal of treatment is to reduce inflammation and pain while minimizing adverse effects, and Voltaren gel can be an effective option when used appropriately. In real-life clinical medicine, the decision to use Voltaren gel and the determination of the optimal dose and frequency should be made on a case-by-case basis, taking into account the individual patient's needs and medical history.

- According to the studies, the following doses and frequencies have been used:
- It is essential to note that the efficacy and safety of these different doses and frequencies may vary, and the optimal treatment regimen should be determined by a healthcare professional based on individual patient needs 3, 4, 5, 6, 7.
Efficacy and Safety
- The studies suggest that topical diclofenac gel is effective in reducing pain and improving function in patients with osteoarthritis of the knee 3, 4, 6, 7.
- The safety profiles of the different doses and frequencies are generally similar, with the most common adverse events being application site reactions, such as dryness, rash, and irritation 3, 4, 6, 7.
- However, the incidence of adverse events may vary depending on the specific product and dose used, and patients should be monitored closely for any signs of adverse reactions 3, 4, 6, 7.
