Diclofenac topical gel is commonly used to treat actinic keratosis, a skin condition caused by prolonged sun exposure. While it can be effective, there are risks associated with its use:

  • Skin Irritation: Some people may experience redness, itching, or irritation at the application site.
  • Allergic Reactions: Rarely, diclofenac gel can cause allergic reactions, leading to symptoms such as rash, hives, swelling, or difficulty breathing.
  • Systemic Absorption: Although topical application minimizes systemic absorption, some diclofenac can still enter the bloodstream, potentially leading to systemic side effects like stomach ulcers, kidney problems, or cardiovascular issues.
  • Photosensitivity: Diclofenac can make your skin more sensitive to sunlight, increasing the risk of sunburn or other sun-related skin damage.
  • Drug Interactions: It’s essential to consult a healthcare professional before using diclofenac gel, especially if you’re taking other medications, as it can interact with certain drugs.
  • Pregnancy and Breastfeeding: Pregnant or breastfeeding women should use diclofenac gel cautiously, as its safety in these populations is not well established.

Always follow your healthcare provider’s instructions carefully and discuss any concerns or potential risks before starting treatment with diclofenac gel.

Why is this medication prescribed?

Diclofenac topical gel is prescribed for the treatment of actinic keratosis, a skin condition characterized by rough, scaly patches caused by prolonged exposure to sunlight. Actinic keratosis lesions are precancerous and can potentially develop into skin cancer if left untreated.

How should this medicine be used?

When used topically, diclofenac gel works by reducing inflammation and cell proliferation, helping to eliminate or reduce the appearance of actinic keratosis lesions.

Here’s how diclofenac topical gel is typically used:

  • Preparation: Before applying the gel, clean and dry the affected area thoroughly.
  • Application: Apply a thin layer of diclofenac gel to the affected skin area(s) and gently rub it in until absorbed. It’s important to use enough gel to cover the entire area but avoid using excessive amounts.
  • Frequency: Diclofenac gel is usually applied twice daily, in the morning and evening, for a specified treatment duration as prescribed by your healthcare provider. Treatment courses typically range from several weeks to a few months.
  • Sun Exposure: While using diclofenac gel, it’s essential to minimize sun exposure and protect treated areas from sunlight by wearing protective clothing and using sunscreen.
  • Regular Monitoring: During treatment, your healthcare provider may schedule regular follow-up appointments to monitor the progress of your condition and adjust treatment if necessary.
  • Complete Course: To achieve the best results, it’s important to complete the full course of treatment as prescribed, even if the symptoms improve before the treatment period ends.

Always follow your healthcare provider’s instructions and recommendations regarding the use of diclofenac topical gel for actinic keratosis. If you have any questions or concerns about its use, consult your healthcare provider for guidance.

Other uses for this medicine

As for other uses, diclofenac topical gel may also be used to relieve pain and inflammation caused by conditions such as arthritis or sports injuries. However, for these conditions, diclofenac is more commonly available in oral or injectable forms.

What special precautions should I follow?

Special precautions should be taken when using diclofenac topical gel for actinic keratosis or any other condition. Here are some important considerations:

  • Allergies: Inform your healthcare provider if you have a known allergy to diclofenac or other nonsteroidal anti-inflammatory drugs (NSAIDs) before using the gel.
  • Skin Sensitivity: If you have sensitive skin or a history of skin reactions, use diclofenac gel with caution and monitor for any signs of irritation or allergic reaction.
  • Avoid Contact with Eyes and Mucous Membranes: Diclofenac gel is for external use only. Avoid contact with eyes, mouth, nose, or other mucous membranes. If accidental contact occurs, rinse thoroughly with water.
  • Sun Exposure: As diclofenac gel can increase sensitivity to sunlight, take measures to protect treated skin areas from direct sunlight, including wearing protective clothing and using sunscreen.
  • Pregnancy and Breastfeeding: If you are pregnant, planning to become pregnant, or breastfeeding, discuss the risks and benefits of using diclofenac gel with your healthcare provider before starting treatment.
  • Drug Interactions: Inform your healthcare provider about all medications, supplements, and herbal products you are taking, as diclofenac gel may interact with certain medications.
  • Medical Conditions: Inform your healthcare provider about any medical conditions you have, especially if you have a history of stomach ulcers, kidney problems, or cardiovascular disease.

Always follow your healthcare provider’s instructions and recommendations when using diclofenac topical gel, and consult them if you have any questions or concerns about its use or potential side effects.

What special dietary instructions should I follow?

Regarding dietary instructions, there are no specific dietary restrictions associated with diclofenac topical gel for actinic keratosis. However, maintaining a healthy and balanced diet can support overall skin health and may complement the treatment process.

What should I do if I forget a dose?

If you forget to apply a dose of diclofenac topical gel, apply it as soon as you remember. However, if it’s almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not apply extra gel to make up for the missed dose. If you have any concerns or questions about missed doses, consult your healthcare provider or pharmacist for guidance.

What side effects can this medication cause?

Diclofenac topical gel, used for treating actinic keratosis, may cause some side effects. Common side effects may include:

  • Skin Irritation: This can manifest as redness, itching, burning sensation, or dryness at the application site.
  • Skin Reactions: Some individuals may experience allergic reactions, such as rash, hives, or swelling of the face, lips, tongue, or throat.
  • Photosensitivity: Diclofenac gel can make the skin more sensitive to sunlight, increasing the risk of sunburn or other sun-related skin damage.
  • Peeling or Blistering: In some cases, the skin may peel or develop blisters at the application site.
  • Stinging or Tingling Sensation: Some people may feel stinging or tingling upon applying the gel.
  • Dry Skin: Prolonged use of diclofenac gel may lead to dryness of the skin at the application site.
  • Contact Dermatitis: Rarely, individuals may develop contact dermatitis, characterized by redness, swelling, or irritation at the site of contact with the gel.
  • Systemic Side Effects: While less common with topical application, diclofenac can still be absorbed into the bloodstream, potentially leading to systemic side effects such as stomach ulcers, kidney problems, or cardiovascular issues. However, the risk of systemic side effects is lower with topical use compared to oral administration.

If you experience any severe or persistent side effects while using diclofenac gel, it’s essential to discontinue use and consult your healthcare provider for further evaluation and guidance. They may recommend adjusting the dosage, discontinuing the medication, or exploring alternative treatment options.
