Can diclofenac (Voltaren) gel be used concurrently with topical muscle rubs?

From the Guidelines

It's generally not recommended to use diclofenac gel at the same time as muscle rub on the same area of skin. These products can interact with each other and potentially increase the risk of skin irritation or other side effects. Diclofenac gel is a prescription nonsteroidal anti-inflammatory drug (NSAID) that reduces pain and inflammation, while muscle rubs typically contain ingredients like menthol, camphor, or methyl salicylate that create warming or cooling sensations. Using both simultaneously could enhance absorption of the medications through the skin, potentially increasing systemic exposure and side effects. Additionally, the combination might cause excessive skin irritation, redness, or burning.

Some key points to consider:

• High-certainty evidence showed that topical NSAIDs were among the most effective interventions for treatment satisfaction 1.
• Moderate-certainty evidence showed that acetaminophen plus oral diclofenac, oral NSAIDs, and topical NSAIDs were among the most effective interventions for symptom relief 1.
• Dermatologic adverse events did not differ significantly between any intervention and placebo, but GI adverse events were increased with oral NSAIDs 1.
• If you need pain relief, choose one product and follow its specific instructions. If one product doesn't provide adequate relief, wait until it has been completely removed from the skin (usually by washing the area thoroughly) before applying the other product.
• Always consult with your healthcare provider or pharmacist before combining topical medications to ensure safe use.

In terms of specific guidance, the evidence suggests that:

• Topical NSAIDs, such as diclofenac gel, can be effective for pain relief and have a relatively low risk of adverse events 1.
• Muscle rubs, which typically contain ingredients like menthol or camphor, can also provide pain relief, but may have a higher risk of skin irritation or other adverse events 1.
• Combining topical NSAIDs with muscle rubs may increase the risk of adverse events, but the evidence is limited and more research is needed to fully understand the potential risks and benefits 1.

From the Research

Diclofenac Gel and Muscle Rub Usage

• There is no direct evidence in the provided studies that addresses the simultaneous use of diclofenac gel and muscle rub.
• However, the studies suggest that topical diclofenac is effective in treating acute and chronic musculoskeletal pain, with minimal adverse events 2, 3.
• The efficacy of topical diclofenac is influenced by its formulation, with gel formulations showing better results than other formulations 2, 3.
• Muscle rubs often contain ingredients like menthol, capsaicin, or methyl salicylate, which can provide pain relief through different mechanisms than diclofenac.
• While there is no direct evidence on the combined use of diclofenac gel and muscle rub, it is possible that using both products together could provide additive pain relief effects.
• However, it is essential to consider the potential for increased skin irritation or other adverse events when using multiple topical products simultaneously 2, 3.

Safety and Efficacy Considerations

• Topical diclofenac has been shown to be effective and safe for treating musculoskeletal pain, with minimal systemic adverse events 2, 3, 4.
• The use of topical diclofenac can be considered a first-line treatment option for knee and hand osteoarthritis, especially for older patients or those with comorbid conditions 4.
• Paracetamol, often used as a first-line analgesic, has been questioned for its therapeutic value and safety, and its use should be carefully considered, especially in elderly or frail patients 5, 6.
• When using any topical pain relief products, it is crucial to follow the recommended dosage and application instructions to minimize the risk of adverse events.
