From the Guidelines
Alternatives to 3% diclofenac include 5-fluorouracil and imiquimod, which are recommended as field treatments for actinic keratosis with moderate to strong evidence 1. These medications have been shown to be effective in treating actinic keratosis, with 5-fluorouracil demonstrating a complete clearance rate of 77% in individual AKs 1. Imiquimod, on the other hand, has been shown to have a complete clearance rate of 50% in a meta-analysis of five RCTs 1. Other alternatives may include cryosurgery, photodynamic therapy, and ingenol mebutate, which have been conditionally recommended for the treatment of actinic keratosis 1. Some key points to consider when choosing an alternative to 3% diclofenac include:
- The strength of evidence supporting the use of each alternative, with 5-fluorouracil and imiquimod having moderate to strong evidence 1
- The potential side effects and risks associated with each alternative, such as the cardiovascular and gastrointestinal risks associated with NSAIDs 1
- The individual patient's medical history and comorbidities, which may affect the choice of alternative treatment
- The need for careful counseling and monitoring of patients to anticipate and manage potential side effects, particularly with imiquimod 1. It is essential to consult with a healthcare provider before changing medications, especially for patients with cardiovascular, renal, or gastrointestinal conditions, as NSAIDs carry different risk profiles depending on the specific drug and medical history 1.

From the Research
Alternatives to 3% Diclofenac
Alternatives to 3% diclofenac for the treatment of actinic keratosis include:
- Topical 5-fluorouracil (5-FU) 2, 3, 4, 5, 6
- Imiquimod 2, 3, 4, 5, 6
- Photodynamic therapy (PDT) 2, 3, 4, 6
- Cryotherapy 3, 5, 6
- Ingenol mebutate (IMB) 3
- Trichloroacetic acid (TCA) 3
- Ablative fractional laser (AFXL) 3
- Nicotinamide and acitretin for chemoprevention 4
- Tirbanibulin ointment, which has shown promising aesthetic outcomes, including skin lightening and a reduction in mottled pigmentation 2
Efficacy Comparison
The efficacy of these alternatives compared to 3% diclofenac varies:
- 5-FU is regarded as the most effective therapy for actinic keratosis 4
- PDT has emerged as a highly effective treatment, demonstrating improved collagen synthesis, skin texture, and pigmentation 2
- Imiquimod has been shown to enhance dermal fibroplasia and reduce solar elastosis 2
- Cryotherapy is recommended for treating single AK lesions 5
- Diclofenac has been found to be less efficacious than 5% 5-FU, 3.75-5% imiquimod, and photodynamic light therapy, despite its favorable side effect profile 4
