Recent heart attack.
Current use of other NSAIDs, salicylate drugs (e.g., aspirin), or pemetrexed.
Fertility issues or ongoing fertility evaluation.
Pregnancy and Fertility Considerations:
If you are pregnant, plan to become pregnant, or become pregnant while taking this medication, inform your doctor. This drug may harm an unborn baby if taken after 20 weeks of pregnancy.
Between 20 and 30 weeks of pregnancy, only take this medication if your doctor advises you to do so.
Do not take this medication if you are more than 30 weeks pregnant.
Interactions with Other Medications and Health Conditions:
This list is not exhaustive, and it is essential to discuss all your medications (prescription, over-the-counter, natural products, and vitamins) and health conditions with your doctor and pharmacist.
Verify that it is safe to take this medication with your other medications and health conditions.
* Never start, stop, or change the dose of any medication without consulting your doctor.
Precautions & Cautions
High blood pressure is a potential side effect of this medication. Ensure that your blood pressure is checked as frequently as advised by your doctor. If you are a smoker, discuss this with your doctor, as smoking may impact your treatment. Additionally, if you have asthma, consult with your doctor, as you may be more sensitive to this medication.
Before consuming alcohol, talk to your doctor to understand any potential risks. It is vital to use this medication only on healthy skin, avoiding any areas with problems. Do not exceed the prescribed dosage, as this may lead to severe side effects. Also, do not use this medication for a longer duration than recommended by your doctor.
To minimize potential risks, avoid exposing the treated area to sunlight. It is crucial to be aware that the use of this medication may increase the risk of heart failure. If you already have heart failure, your risk of heart attack, hospitalization due to heart failure, and death may be higher. Discuss these risks with your doctor.
Furthermore, people who have had a recent heart attack may have a higher risk of heart attack and heart-related death when taking this medication. In fact, studies have shown that individuals taking this medication after a first heart attack were more likely to die within a year compared to those not taking it. If you are taking aspirin to prevent a heart attack, consult with your doctor.
Liver problems, which can be fatal, have been associated with this medication. Be vigilant for signs of liver problems, including dark urine, fatigue, decreased appetite, stomach upset or pain, pale stools, vomiting, or yellowing of the skin and eyes. If you experience any of these symptoms, contact your doctor immediately.
In case of accidental ingestion, this medication can cause harm. If swallowed, promptly call a doctor or a poison control center. This medication is not approved for use in children, so it is essential to discuss any concerns with your doctor.
If you are 60 years or older, use this medication with caution, as you may be more susceptible to side effects. It is also important to note that NSAIDs, like this medication, may affect ovulation, potentially impacting fertility. However, this effect is reversible once the medication is stopped. Discuss any concerns with your doctor.
Finally, if you are breastfeeding, consult with your doctor to weigh the potential risks to your baby.
Overdose Information
Overdose Symptoms:
- Overdose with topical diclofenac is unlikely due to minimal systemic absorption. However, if large amounts are ingested or applied to extensive areas of compromised skin, systemic NSAID overdose symptoms may occur:
- Lethargy, drowsiness
- Nausea, vomiting, epigastric pain
- Gastrointestinal bleeding
- Rarely: hypertension, acute renal failure, respiratory depression, coma
What to Do:
In case of suspected overdose, seek immediate medical attention or call a poison control center (e.g., 1-800-222-1222). Treatment is symptomatic and supportive. Gastric decontamination is generally not necessary for topical overdose.
Drug Interactions
Contraindicated Interactions
- In the setting of coronary artery bypass graft (CABG) surgery (due to systemic NSAID risk).
Major Interactions
- Anticoagulants (e.g., warfarin): Increased risk of bleeding.
- Antiplatelet agents (e.g., aspirin, clopidogrel): Increased risk of bleeding.
- Lithium: Increased lithium levels and potential for toxicity.
- Methotrexate: Increased methotrexate levels and potential for toxicity.
- Diuretics (e.g., furosemide, hydrochlorothiazide): Reduced diuretic and antihypertensive effects, potential for renal impairment.
- ACE inhibitors/ARBs: Reduced antihypertensive effect, increased risk of renal impairment and hyperkalemia.
- Other NSAIDs (systemic or topical): Increased risk of adverse effects (GI, renal).
Moderate Interactions
- Digoxin: Increased digoxin levels.
- Cyclosporine: Increased risk of nephrotoxicity.
- Tacrolimus: Increased risk of nephrotoxicity.
- SSRIs/SNRIs: Increased risk of GI bleeding.
Minor Interactions
- Not many specific minor interactions for topical diclofenac due to low systemic absorption. However, general caution with drugs metabolized by CYP2C9/2C19.
Monitoring
Baseline Monitoring
Rationale: To ensure gel is not applied to open wounds or infected areas, which could increase systemic absorption or local irritation.
Timing: Prior to initiation of treatment.
Routine Monitoring
Frequency: Daily, or at each application.
Target: Minimal to no irritation.
Action Threshold: Severe or persistent irritation, blistering, or signs of allergic reaction (e.g., urticaria, angioedema) warrant discontinuation and medical evaluation.
Frequency: Monthly, or at follow-up visits.
Target: Reduction in size, number, or severity of lesions.
Action Threshold: Lack of improvement after 60-90 days, or worsening of lesions.
Symptom Monitoring
- Skin irritation (redness, itching, burning, dryness, rash, scaling)
- Photosensitivity (sunburn-like reaction)
- Signs of systemic NSAID effects (rare with topical use but possible with extensive application or compromised skin):
- Gastrointestinal symptoms (e.g., abdominal pain, indigestion, black/tarry stools, vomiting blood)
- Cardiovascular symptoms (e.g., chest pain, shortness of breath, swelling of ankles/feet)
- Renal symptoms (e.g., decreased urine output, swelling)
- Unusual bleeding or bruising
- Allergic reactions (e.g., hives, swelling of face/lips/tongue/throat, difficulty breathing)
Special Patient Groups
Pregnancy
Diclofenac, like other NSAIDs, should be avoided in the third trimester of pregnancy due to the risk of premature closure of the fetal ductus arteriosus. Use in the first and second trimesters should only occur if the potential benefit justifies the potential risk to the fetus, and at the lowest effective dose for the shortest duration possible. The FDA's Pregnancy and Lactation Labeling Rule (PLLR) advises against NSAID use after 20 weeks gestation due to risk of fetal renal dysfunction and oligohydramnios.
Trimester-Specific Risks:
Lactation
Diclofenac is excreted in human milk in small amounts after systemic administration. While systemic absorption from topical application is minimal, caution should be exercised when diclofenac gel is administered to a nursing woman. Consider the developmental and health benefits of breastfeeding along with the motherβs clinical need for diclofenac and any potential adverse effects on the breastfed infant from diclofenac or from the underlying maternal condition.
Pediatric Use
Safety and effectiveness of diclofenac 3% gel for actinic keratosis have not been established in pediatric patients.
Geriatric Use
No specific dose adjustment is required for elderly patients. However, elderly patients may be more susceptible to the adverse effects of NSAIDs, particularly gastrointestinal bleeding and renal impairment, if significant systemic absorption occurs. Use with caution and monitor for adverse reactions.
Clinical Information
Clinical Pearls
- Diclofenac 3% gel (Solaraze) is specifically indicated for the topical treatment of actinic keratosis, not for general pain relief.
- Treatment typically requires 60 to 90 days for optimal results, and complete healing may not be evident until 30 days after stopping therapy.
- Patients should be advised to protect treated areas from sun exposure and artificial UV light due to potential photosensitivity.
- Wash hands thoroughly after applying the gel to avoid accidental transfer to eyes or other sensitive areas.
- While systemic absorption is low, patients should be monitored for signs of systemic NSAID adverse effects, especially if large areas are treated or skin integrity is compromised.
Alternative Therapies
- 5-Fluorouracil topical (e.g., Efudex, Carac)
- Imiquimod topical (e.g., Aldara, Zyclara)
- Ingenol mebutate topical (e.g., Picato - Note: Picato was voluntarily withdrawn from market due to safety concerns)
- Photodynamic therapy (PDT) with aminolevulinic acid (e.g., Levulan Kerastick)
- Cryosurgery (liquid nitrogen)
- Curettage and electrodessication
- Excisional surgery
