ALERT: US Boxed Warning
Serious cardiovascular thrombotic events (diclofenac 3% gel, Flector, Klofensaid II, Pennsaid, and Voltaren):

Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use.

Diclofenac is contraindicated in the setting of coronary artery bypass graft surgery.

Serious GI bleeding, ulceration, and perforation (diclofenac 3% gel, Flector, Klofensaid II, Pennsaid, and Voltaren):

NSAIDs cause an increased risk of serious GI adverse reactions, including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These reactions can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk of serious GI events.

Dosing: Adult

Dosage guidance:

Safety: Use the lowest effective dose for the shortest duration of time; however, adverse effects associated with systemic diclofenac (eg, GI bleeding, cardiovascular thrombotic events, kidney toxicity) are less likely with topical formulations due to minimal systemic absorption.

Clinical considerations: Concurrent use with systemic nonsteroidal anti-inflammatory drugs (NSAIDs) is generally not recommended as topical treatment is unlikely to provide added pain relief.

Actinic keratosis

Actinic keratosis (alternative agent):

Topical: Gel 3%: Apply to lesion area twice daily for 60 to 90 days. Normally, 0.5 g is used on each 5 cm × 5 cm lesion.

Acute pain

Acute pain (eg, musculoskeletal):

Topical: Patch 1.3%: Apply 1 patch once (Licart) or twice (Flector) daily to most painful area.

Topical: Gel 1% (OTC or Rx) (off-label use): Apply up to 4 g to each affected area up to 4 times daily; maximum dose per area: 16 g/day; maximum total body dose (all combined areas): 32 g/day. Note: Dosing is based on general recommendations from manufacturer labeling.

Topical: Gel 1.16% (Canadian OTC product): Apply up to 4 g to affected area up to 4 times daily; amount needed depends on size of the painful area; 2 to 4 g is sufficient to treat an area of ~400 to 800 cm2.

Topical: Gel 2.32% (Canadian OTC product): Apply 2 g to affected area up to twice daily.

Osteoarthritis

Osteoarthritis:

Lower extremity (eg, knee):

Topical: Gel 1% (OTC or Rx): Apply 4 g to each affected area up to 4 times daily; maximum dose per joint: 16 g/day; maximum total body dose (all combined joints): 32 g/day.

Topical: Solution 1.5%: Apply 40 drops to each affected knee up to 4 times daily. Note: Apply 10 drops at a time, rub in evenly, then apply 10 more drops until a total of 40 drops has been applied.

Topical: Solution 2%: Apply 40 mg (2 pump actuations) to each affected knee up to twice daily.

Upper extremity (eg, hand):

Topical: Gel 1% (OTC or Rx): Apply 2 g to each affected area up to 4 times daily; maximum dose per joint: 8 g/day; maximum total body dose (all combined joints): 32 g/day.

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Dosing: Kidney Impairment: Adult

The renal dosing recommendations are based upon the best available evidence and clinical expertise. Senior Editorial Team: Bruce Mueller, PharmD, FCCP, FASN, FNKF; Jason A. Roberts, PhD, BPharm (Hons), B App Sc, FSHP, FISAC; Michael Heung, MD, MS.

Altered kidney function:

eGFR ≥30 mL/minute/1.73 m2: No dosage adjustment necessary (Ref).

eGFR <30 mL/minute/1.73 m2: The manufacturer’s labeling recommends avoiding use in advanced impairment. Although topical diclofenac does have some limited absorption, the incidence of clinically significant acute kidney injury from topical nonsteroidal anti-inflammatory drugs appears to be low. No dosage adjustment necessary; monitor kidney function closely at onset of use (Ref).

Hemodialysis, intermittent (thrice weekly): Unlikely to be dialyzed (highly protein bound): No supplemental dose or dosage adjustment necessary (Ref).

Peritoneal dialysis: Unlikely to be dialyzed (highly protein bound): No dosage adjustment necessary (Ref).

Dosing: Hepatic Impairment: Adult

There are no dosage adjustments provided in the manufacturer's labeling; use with caution.

Dosing: Older Adult

Start at lower end of dosing range. Refer to adult dosing.

Dosing: Pediatric

(For additional information see "Diclofenac (topical): Pediatric drug information")

Acute pain

Acute pain (strains, sprains, contusions): Topical: Note: Use the lowest effective dose for the shortest duration of time, consistent with individual patient treatment goals.

Patch (Flector): Children ≥6 years and Adolescents: Apply 1 patch 2 times daily to most painful area for up to 14 days; Note: Coadministration with oral NSAIDs is not recommended.

Gel (Voltaren Emulgel 1.16% [Canadian product]): Adolescents ≥16 years: Apply to skin of affected area(s) 3 or 4 times daily for up to 7 days; Note: 2 to 4 g should be adequate to treat an area 400 to 800 cm2 (1 g is ~2 cm long strip of gel).

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Dosing: Kidney Impairment: Pediatric

There are no dosage adjustments provided in the manufacturer's labeling; avoid use in patients with advanced renal disease.

Warnings/Precautions

Concerns related to adverse effects:

• Anaphylactoid reactions: Even in patients without prior exposure, anaphylactoid reactions may occur; patients with "aspirin triad" (bronchial asthma, aspirin intolerance, rhinitis) may be at increased risk. Contraindicated in patients who experience bronchospasm, asthma, rhinitis, or urticaria with NSAID or aspirin therapy (excluding 3% gel).

• Cardiovascular events: [US Boxed Warning]: NSAIDs cause an increased risk of serious (and potentially fatal) adverse cardiovascular thrombotic events, including MI and stroke. Risk may occur early during treatment and may increase with duration of use. Relative risk appears to be similar in those with and without known cardiovascular disease or risk factors for cardiovascular disease; however, absolute incidence of serious cardiovascular thrombotic events (which may occur early during treatment) was higher in patients with known cardiovascular disease or risk factors. New-onset hypertension or exacerbation of hypertension may occur (NSAIDs may also impair response to ACE inhibitors, thiazide diuretics, or loop diuretics); may contribute to cardiovascular events; monitor blood pressure; use with caution in patients with hypertension. May cause sodium and fluid retention, use with caution in patients with edema. Avoid use in patients with heart failure (FDA 2015). Avoid use in patients with recent MI unless benefits outweigh risk of cardiovascular thrombotic events. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of cardiovascular events; alternate therapies should be considered for patients at high risk.

• Drug reaction with eosinophilia and systemic symptoms: Potentially serious, sometimes fatal, drug reaction with eosinophilia and systemic symptoms (DRESS), also known as multiorgan hypersensitivity reactions, has been reported with NSAIDs. Monitor for signs and symptoms (eg, fever, rash, lymphadenopathy, eosinophilia) in association with other organ system involvement (eg, hepatitis, nephritis, hematological abnormalities, myocarditis, myositis). Early symptoms of hypersensitivity reaction (eg, lymphadenopathy, fever) may occur without rash; discontinue therapy and further evaluate if DRESS is suspected.

• Gastrointestinal events: [US Boxed Warning]: NSAIDs cause an increased risk of serious gastrointestinal inflammation, ulceration, bleeding, and perforation (may be fatal); elderly patients and patients with history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events. These events may occur at any time during therapy and without warning. Avoid use in patients with active GI bleeding. Use caution with a history of GI ulcers, concurrent therapy known to increase the risk of GI bleeding (eg, aspirin, anticoagulants and/or corticosteroids, selective serotonin reuptake inhibitors), advanced hepatic disease, coagulopathy, smoking, use of alcohol, or in elderly or debilitated patients. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of GI adverse events; alternate therapies should be considered for patients at high risk. When used concomitantly with aspirin, a substantial increase in the risk of gastrointestinal complications (eg, ulcer) occurs; concomitant gastroprotective therapy (eg, proton pump inhibitors) is recommended (Bhatt 2008).

• Hematologic effects: Platelet adhesion and aggregation may be decreased; may prolong bleeding time; patients with coagulation disorders or who are receiving anticoagulants should be monitored closely. Anemia may occur; patients on long-term NSAID therapy should be monitored for anemia. Rarely, NSAID use has been associated with potentially severe blood dyscrasias (eg, agranulocytosis, thrombocytopenia, aplastic anemia).

• Hepatic effects: Transaminase elevations have been observed with oral chronic use; closely monitor patients with any abnormal LFT. Rare (sometimes fatal) severe hepatic reactions (eg, fulminant hepatitis, hepatic necrosis, hepatic failure) have occurred with NSAID use; discontinue immediately if signs or symptoms of hepatic disease develop or if systemic manifestations occur.

• Hyperkalemia: NSAID use may increase the risk of hyperkalemia, particularly in the elderly, diabetics, renal disease, and with concomitant use of other agents capable of inducing hyperkalemia (eg, ACE inhibitors). Monitor potassium closely.

• Renal effects: NSAID use may compromise existing renal function; dose-dependent decreases in prostaglandin synthesis may result from NSAID use, reducing renal blood flow, which may cause renal decompensation (usually reversible). Patients with impaired renal function, dehydration, hypovolemia, heart failure, hepatic impairment, those taking diuretics and ACE inhibitors, and the elderly are at greater risk of renal toxicity. Long-term NSAID use may result in renal papillary necrosis and other renal injury/toxicity.

• Skin reactions: May cause potentially fatal serious skin adverse events, including exfoliative dermatitis, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN); may occur without warning; discontinue use at first sign of skin rash (or any other hypersensitivity). Do not apply topical products to open skin wounds, infected areas, inflammations, or exfoliative dermatitis.

Disease-related concerns:

• Asthma: Contraindicated in patients with aspirin-sensitive asthma (excluding 3% gel); severe and potentially fatal bronchospasm may occur. Use caution in patients with other forms of asthma.

• Coronary artery bypass graft surgery: [US Boxed Warning]: Use is contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Risk of MI and stroke may be increased with use following CABG surgery.

• Hepatic impairment: Use with caution in patients with hepatic impairment; patients with advanced hepatic disease are at an increased risk of GI bleeding with NSAIDs.

• Renal impairment: Avoid use in advanced renal disease.

Special populations:

• Older adult: Elderly patients are at greater risk for serious GI, cardiovascular and/or renal adverse events; use with caution.

Dosage form specific issues:

• Appropriate use: Avoid contact with eyes and mucous membranes.

• Benzoyl alcohol and derivatives: Some dosage forms may contain benzoyl alcohol; large amounts of benzoyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity ("gasping syndrome") in neonates; the "gasping syndrome" consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension and cardiovascular collapse (AAP ["Inactive" 1997]; CDC, 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzoyl alcohol with caution in neonates. See manufacturer's labeling.

• Gel: Avoid occlusive dressings and/or heat application to treated area.

• Patch: Contains conducting metal (eg, aluminum); remove patch prior to MRI.

• Gel, patch, solution: Combination use with oral NSAIDs is not recommended due to increased risk of adverse reactions (eg, rectal hemorrhage; more frequent abnormal creatinine, urea, hemoglobin); do not use concomitantly unless benefit outweighs risks, and monitor patient with periodic laboratory evaluations.

Other warnings/precautions:

• Self-medication (OTC use): Prior to self-medication, patients should contact health care provider if they have had recurring stomach pain; ulcers; bleeding problems; high blood pressure; asthma; heart, liver, or kidney disease; other serious medical problems; are currently taking a diuretic, aspirin, or anticoagulant; or are ≥60 years of age. Discontinue use and contact health care provider if pain gets worse or lasts >21 days; redness or swelling occurs in affected area; fever or skin irritation occurs; signs of GI bleeding, heart disease, or stroke occur. Onset of pain relief may take up to 7 days after starting therapy; discontinue use if no pain relief after 7 days.

Warnings: Additional Pediatric Considerations

Children and adolescents may experience a higher frequency of certain adverse effects than adults, particularly headache (9% vs 1%) and dyspepsia (3% to 1%).

If salicylates and topical NSAIDs are coadministered, ensure the benefits outweigh the risks and monitor for increased NSAID toxicities. Risk D: Consider therapy modification

Selective Serotonin Reuptake Inhibitors: Nonsteroidal Anti-Inflammatory Agents (Topical) may enhance the antiplatelet effect of Selective Serotonin Reuptake Inhibitors. Risk C: Monitor therapy

Serotonin/Norepinephrine Reuptake Inhibitors: May enhance the antiplatelet effect of Nonsteroidal Anti-Inflammatory Agents (Topical). Risk C: Monitor therapy

Tacrolimus (Systemic): Nonsteroidal Anti-Inflammatory Agents (Topical) may enhance the nephrotoxic effect of Tacrolimus (Systemic). Risk C: Monitor therapy

Tenofovir Products: Nonsteroidal Anti-Inflammatory Agents (Topical) may enhance the nephrotoxic effect of Tenofovir Products. Risk C: Monitor therapy

Thiazide and Thiazide-Like Diuretics: Nonsteroidal Anti-Inflammatory Agents (Topical) may diminish the therapeutic effect of Thiazide and Thiazide-Like Diuretics. Risk C: Monitor therapy

Voriconazole: May increase the serum concentration of Diclofenac (Topical). Risk C: Monitor therapy

Reproductive Considerations

Nonsteroidal anti-inflammatory drugs (NSAIDs) may delay or prevent rupture of ovarian follicles. This may be associated with infertility that is reversible upon discontinuation of the medication. Consider discontinuing use in patients having difficulty conceiving or those undergoing investigation of fertility.

Based on available information, NSAIDs can be continued in patients with rheumatic and musculoskeletal diseases who are planning to father a child (ACR [Sammaritano 2020]).

Pregnancy Considerations

Diclofenac crosses the placenta following systemic administration.

The amount of diclofenac available systemically following topical application is less in comparison to oral doses.

Birth defects have been observed following in utero nonsteroidal anti-inflammatory drug (NSAID) exposure in some studies; however, data are conflicting (Bloor 2013). Nonteratogenic effects, including prenatal constriction of the ductus arteriosus, persistent pulmonary hypertension of the newborn, oligohydramnios, necrotizing enterocolitis, renal dysfunction or failure, and intracranial hemorrhage, have been observed in the fetus/neonate following in utero NSAID exposure (Bermas 2014; Bloor 2013). Maternal NSAID use may cause fetal renal dysfunction leading to oligohydramnios. Although rare, this may occur as early as 20 weeks' gestation and is more likely to occur with prolonged maternal use. Oligohydramnios may be reversible following discontinuation of the NSAID (Dathe 2019). In addition, nonclosure of the ductus arteriosus postnatally may occur and be resistant to medical management (Bermas 2014; Bloor 2013).

Maternal use of NSAIDs should be avoided beginning at 20 weeks' gestation. If NSAID use is necessary between 20 and 30 weeks' gestation, limit use to the lowest effective dose and shortest duration possible; consider ultrasound monitoring of amniotic fluid if treatment extends beyond 48 hours and discontinue the NSAID if oligohydramnios is found. Reversible constriction of the ductus arteriosus in utero has been observed following topical application of diclofenac (Torloni 2006). Because NSAIDs may cause premature closure of the ductus arteriosus, product labeling for diclofenac specifically states use should be avoided starting at 30 weeks' gestation.

Based on available information, NSAIDs can be continued during the first 2 trimesters of pregnancy in patients with rheumatic and musculoskeletal diseases; use in the third trimester is not recommended (ACR [Sammaritano 2020]).

Breastfeeding Considerations

Diclofenac is present in breast milk following oral administration. It is not known if diclofenac can be detected in breast milk following topical application.

The amount of diclofenac available systemically following topical application is less in comparison to oral doses. Nonsteroidal anti-inflammatory drugs are considered compatible for use in patients with rheumatic and musculoskeletal diseases who are breastfeeding; agents with a short half-life and established safety data in infants may be preferred (ACR [Sammaritano 2020]). According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and benefits of treatment to the mother.

Monitoring Parameters

CBC, liver enzymes (periodically during chronic therapy starting 4 to 8 weeks after initiation), BUN/serum creatinine; potassium; monitor urine output; occult blood loss; blood pressure (baseline and during treatment)

Mechanism of Action

Reversibly inhibits cyclooxygenase-1 and 2 (COX-1 and 2) enzymes, which results in decreased formation of prostaglandin precursors; has antipyretic, analgesic, and anti-inflammatory properties

Other proposed mechanisms not fully elucidated (and possibly contributing to the anti-inflammatory effect to varying degrees), include inhibiting chemotaxis, altering lymphocyte activity, inhibiting neutrophil aggregation/activation, and decreasing proinflammatory cytokine levels.
