Topical Treatments for Localized Pain and Inflammation

First-Line Treatment Options

The American Geriatrics Society recommends topical lidocaine as a first-line option for localized neuropathic pain, with moderate quality evidence and a strong recommendation 1
The American Geriatrics Society suggests topical NSAIDs, particularly diclofenac, as a first-line option for localized musculoskeletal pain, with moderate quality evidence and a weak recommendation 1
The European League Against Rheumatism recommends topical diclofenac gel as the first line of treatment for wrist and hand pain, providing significant improvement in pain and function after 8 weeks of use 2
Consider topical diclofenac as first-line therapy before oral NSAIDs, especially in elderly patients, patients with gastrointestinal risk factors, and those with cardiovascular or renal comorbidities 2, 3

Capsaicin is considered an alternative option for peripheral neuropathic pain, with moderate quality evidence and a weak recommendation, and a single 30-minute application of 8% capsaicin patch can provide pain relief for up to 12 weeks, as suggested by the Clinical Infectious Diseases guidelines 4
Capsaicin or lidocaine may be more suitable for significant neuropathic pain components 5, 6

The American Society of Anesthesiologists and American Society of Regional Anesthesia and Pain Medicine do not specifically mention CBD in their recommendations for topical agents, indicating a lack of evidence for its use 7
The American Diabetes Association recommends lidocaine patches/gel for pain with neuropathic components 8
The American College of Rheumatology conditionally recommends both topical diclofenac and oral acetaminophen for osteoarthritis pain management 9

Patients with localized neuropathic pain may be candidates for topical lidocaine, according to the American Geriatrics Society 1
Patients ≥75 years old, topical NSAIDs are strongly preferred over oral NSAIDs due to reduced systemic effects 9
Patients with known hypersensitivity to diclofenac, history of asthma, urticaria, or allergic reactions after taking aspirin or other NSAIDs should avoid diclofenac gel 10
Absolute contraindications for diclofenac gel include a history of previous severe cutaneous adverse reactions to any NSAID 10

Topical diclofenac gel has demonstrated small but significant improvements in pain and function after 8 weeks compared to placebo in high-quality studies 2
Topical NSAIDs, including diclofenac, have:
Topical NSAIDs can provide pain relief similar to oral NSAIDs 2
Topical NSAIDs have a favorable safety profile compared to oral analgesics, with:

Acetaminophen should be taken at recommended doses (typically 325-650 mg every 4-6 hours, not exceeding 3,000-4,000 mg daily) 12
The recommended application frequency for topical analgesics, such as diclofenac gel, is 3-4 times daily, with a thin layer applied to the affected area 2, 5
Monitor for liver toxicity with acetaminophen, especially with chronic use or doses exceeding 3,000 mg daily 12
Be cautious about hidden sources of acetaminophen in over-the-counter products to prevent accidental overdose 12
It is essential to wash hands thoroughly before and after application, unless treating hands, to minimize systemic absorption 5
Application should be avoided on broken or irritated skin, and not used in combination with heat patches (which increases absorption) 6
Treatment should continue for at least 4 weeks to assess efficacy, with applications 3-4 times daily for best results 5
Patients should be monitored for skin reactions, such as mild redness and irritation, which are the most common adverse effects of topical analgesics 6
Treatment response should be assessed after 2 weeks of consistent use, and alternative topical agents or oral medications should be considered if there is an inadequate response after 4 weeks 13, 6
