🚨 Boxed Warning ▾
BOXED WARNING WARNING: RISK OF SERIOUS CARDIOVASCULAR and GASTROINTESTINAL EVENTS Cardiovascular Thrombotic Events 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 [ see Warnings and Precautions (5.1)]. DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% is contraindicated in the setting of coronary artery bypass graft (CABG) surgery [ see Contraindications (4) and Warnings and Precautions (5.1)] .
Gastrointestinal Bleeding, Ulceration, and Perforation NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events 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 for serious GI events [ see Warnings and Precautions (5.2)].
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% is indicated for the topical treatment of acute pain due to minor strains, sprains, and contusions in adults and pediatric patients 6 years and older.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION
2.1General Dosing Instructions Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [ see Warnings and Precautions (5)]. The recommended dose of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% is one (1) topical system to the most painful area twice a day both in adults and pediatric patients 6 years of age and older.
2.2Special Precautions Inform patients that, if DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% begins to peel-off, the edges of the topical system may be taped down. If problems with adhesion persist, patients may overlay the topical system with a mesh netting sleeve, where appropriate (e.g. to secure topical systems applied to ankles, knees, or elbows). The mesh netting sleeve (e.g.
Curad® Hold Tite™, Surgilast® Tubular Elastic Dressing) must allow air to pass through and not be occlusive (non-breathable). Do not apply DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% to non-intact or damaged skin resulting from any etiology e.g. exudative dermatitis, eczema, infected lesion, burns or wounds. Do not wear a DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% when bathing or showering.
Wash your hands after applying, handling or removing the topical system. Avoid eye contact. Do not use combination therapy with DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and an oral NSAID unless the benefit outweighs the risk and conduct periodic laboratory evaluations.
💊 Dosage Forms and Strengths ▾

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS
5.1Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, including myocardial infarction (MI) and stroke, which can be fatal. Based on available data, it is unclear that the risk for CV thrombotic events is similar for all NSAIDs. The relative increase in serious CV thrombotic events over baseline conferred by NSAID use appears to be similar in those with and without known CV disease or risk factors for CV disease.
However, patients with known CV disease or risk factors had a higher absolute incidence of excess serious CV thrombotic events, due to their increased baseline rate. Some observational studies found that this increased risk of serious CV thrombotic events began as early as the first weeks of treatment. The increase in CV thrombotic risk has been observed most consistently at higher doses.
To minimize the potential risk for an adverse CV event in NSAID-treated patients, use the lowest effective dose for the shortest duration possible. Physicians and patients should remain alert for the development of such events, throughout the entire treatment course, even in the absence of previous CV symptoms. Patients should be informed about the symptoms of serious CV events and the steps to take if they occur.
There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID, such as diclofenac, increases the risk of serious gastrointestinal (GI) events [ see Warnings and Precautions (5.2)]. Status Post Coronary Artery Bypass Graft (CABG) Surgery Two large, controlled clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10–14 days following CABG surgery found an increased incidence of myocardial infarction and stroke.
NSAIDs are contraindicated in the setting of CABG [ see Contraindications (4)]. Post-MI Patients Observational studies conducted in the Danish National Registry have demonstrated that patients treated with NSAIDs in the post-MI period were at increased risk of reinfarction, CV-related death, and all-cause mortality beginning in the first week of treatment. In this same cohort, the incidence of death in the first year post-MI was 20 per 100 person years in NSAID-treated patients compared to 12 per 100 person years in non-NSAID exposed patients.
Although the absolute rate of death declined somewhat after the first year post-MI, the increased relative risk of death in NSAID users persisted over at least the next four years of follow-up. Avoid the use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% in patients with a recent MI unless the benefits are expected to outweigh the risk of recurrent CV thrombotic events. If DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% is used in patients with a recent MI, monitor patients for signs of cardiac ischemia.
5.2Gastrointestinal Bleeding, Ulceration, and Perforation NSAIDs, including diclofenac, cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients who develop a serious upper GI adverse event on NSAID therapy is symptomatic.
Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occurred in approximately 1% of patients treated for 3-6 months, and in about 2%-4% of patients treated for one year. However, even short-term NSAID therapy is not without risk. Risk Factors for GI Bleeding, Ulceration, and Perforation Patients with a prior history of peptic ulcer disease and/or GI bleeding who used NSAIDs had a greater than 10-fold increased risk for developing a GI blee…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Cardiovascular Thrombotic Events [ see Warnings and Precautions (5.1)] GI Bleeding, Ulceration and Perforation [ see Warnings and Precautions (5.2)] Hepatotoxicity [ see Warnings and Precautions (5.3)] Hypertension [ see Warnings and Precautions (5.4)] Heart Failure and Edema [ see Warnings and Precautions (5.5)] Renal Toxicity and Hyperkalemia [ see Warnings and Precautions (5.6)] Anaphylactic Reactions [ see Warnings and Precautions (5.7)] Serious Skin Reactions [ see Warnings and Precautions (5.9)] Hematologic Toxicity [ see Warnings and Precautions (5.12)]
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adult Clinical Trials Experience In controlled trials during the premarketing development of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3%, approximately 600 patients with minor sprains, strains, and contusions were treated with DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% for up to two weeks.
Adverse Events Leading to Discontinuation of Treatment In the controlled trials, 3% of patients in both the DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and placebo groups discontinued treatment due to an adverse event. The most common adverse events leading to discontinuation were application site reactions, occurring in 2% of both the DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and placebo groups. Application site reactions leading to dropout included pruritus, dermatitis, and burning.
Common Adverse Events Overall, the most common adverse events associated with DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% treatment were skin reactions at the site of treatment. Table 1 lists all adverse events, regardless of causality, occurring in ≥ 1% of patients in controlled trials of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3%. A majority of patients treated with DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% had adverse events with a maximum intensity of "mild" or "moderate." Foreign labeling describes that dermal allergic reactions may occur with DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% treatment.
Additionally, the treated area may become irritated or develop itching, erythema, edema, vesicles, or abnormal sensation. Pediatric Clinical Trials Experience In one open-label trial, 104 male and female pediatric patients 6 years and older presenting with minor strains, sprains, and contusions received DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3 % twice a day for as many as 16 days. The most commonly reported adverse events (incidence ≥ 2%) were headache (9%), application site pruritus (7%), nausea (3%), and dyspepsia (3%).
No adverse events led to discontinuation of treatment.
6.2Postmarketing Experience The following adverse reactions have been identified during post-approval use of diclofenac. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Skin and Appendages: Exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), and fixed drug eruption (FDE). adverse reactions
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS See Table 2 for clinically significant drug interactions with diclofenac. Table 2: Clinically Significant Drug Interactions with Diclofenac Drugs That Interfere with Hemostasis Clinical Impact: Diclofenac and anticoagulants such as warfarin have a synergistic effect on bleeding. The concomitant use of diclofenac and anticoagulants have an increased risk of serious bleeding compared to the use of either drug alone.
Serotonin release by platelets plays an important role in hemostasis. Case-control and cohort epidemiological studies showed that concomitant use of drugs that interfere with serotonin reuptake and an NSAID may potentiate the risk of bleeding more than an NSAID alone. Intervention: Monitor patients with concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% with anticoagulants (e.g., warfarin), antiplatelet agents (e.g., aspirin), selective serotonin reuptake inhibitors (SSRIs), and serotonin norepinephrine reuptake inhibitors (SNRIs) for signs of bleeding [ see Warnings and Precautions (5.12)].
Aspirin Clinical Impact: Controlled clinical studies showed that the concomitant use of NSAIDs and analgesic doses of aspirin does not produce any greater therapeutic effect than the use of NSAIDs alone. In a clinical study, the concomitant use of an NSAID and aspirin was associated with a significantly increased incidence of GI adverse reactions as compared to use of the NSAID alone [ see Warnings and Precautions (5.2)]. Intervention: Concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and analgesic doses of aspirin is not generally recommended because of the increased risk of bleeding [ see Warnings and Precautions (5.12)].
DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% is not a substitute for low dose aspirin for cardiovascular protection. ACE Inhibitors, Angiotensin Receptor Blockers, and Beta-Blockers Clinical Impact: NSAIDs may diminish the antihypertensive effect of angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), or beta-blockers (including propranolol). In patients who are elderly, volume-depleted (including those on diuretic therapy), or have renal impairment, co-administration of an NSAID with ACE inhibitors or ARBs may result in deterioration of renal function, including possible acute renal failure.
These effects are usually reversible. Intervention: During concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and ACE-inhibitors, ARBs, or beta-blockers, monitor blood pressure to ensure that the desired blood pressure is obtained. During concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and ACE-inhibitors or ARBs in patients who are elderly, volume-depleted, or have impaired renal function, monitor for signs of worsening renal function [ see Warnings and Precautions (5.6)] .
When these drugs are administered concomitantly, patients should be adequately hydrated. Assess renal function at the beginning of the concomitant treatment and periodically thereafter. Diuretics Clinical Impact: Clinical studies, as well as post-marketing observations, showed that NSAIDs reduced the natriuretic effect of loop diuretics (e.g., furosemide) and thiazide diuretics in some patients.
This effect has been attributed to the NSAID inhibition of renal prostaglandin synthesis. Intervention: During concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% with diuretics, observe patients for signs of worsening renal function, in addition to assuring diuretic efficacy including antihypertensive effects [ see Warnings and Precautions (5.6)]. Digoxin Clinical Impact: The concomitant use of diclofenac with digoxin has been reported to increase the serum concentration and prolong the half-life of digoxin.
Intervention: During concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and digoxin, monitor serum digoxin levels. Lithium Clinical Impact: NSAIDs have produced elevations in plasma lithium levels and reductions in renal lithium clearance . The mean mi…
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Use of NSAIDs, including DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3%, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. Because of these risks, limit dose and duration of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% use between about 20 and 30 weeks of gestation, and avoid DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% use at about 30 weeks of gestation and later in pregnancy ( see Clinical Considerations, Data).
Premature Closure of Fetal Ductus Arteriosus Use of NSAIDs, including DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3%, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Oligohydramnios/Neonatal Renal Impairment Use of NSAIDs at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. Data from observational studies regarding other potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive.
In animal reproduction studies, diclofenac epolamine administered orally to pregnant rats and rabbits during the period of organogenesis produced embryotoxicity at approximately 3 and 7 times, respectively, the topical exposure from the maximum recommended human dose (MRHD) of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3%. In rats, increased incidences of skeletal anomalies and maternal toxicity were also observed at this dose. Diclofenac epolamine administered orally to both male and female rats prior to mating and throughout the mating period, and during gestation and lactation in females produced embryotoxicity at doses approximately 3 and 7 times, respectively, the topical exposure from the MRHD (see Data) .
Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. In animal studies, administration of prostaglandin synthesis inhibitors such as diclofenac, resulted in increased pre- and post-implantation loss. Prostaglandins also have been shown to have an important role in fetal kidney development.
In published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Premature Closure of Fetal Ductus Arteriosus: Avoid use of NSAIDs in women at about 30 weeks gestation and later in pregnancy, because NSAIDs, including DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3%, can cause premature closure of the fetal ductus arteriosus ( see Data). Oligohydramnios/Neonatal Renal Impairment: If an NSAID is necessary at about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective dose and shortest duration possible.
If DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. If oligohydramnios occurs, discontinue DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and follow up according to clinical practice ( see Data). Data Human Data Premature Closure of Fetal Ductus Arteriosus: Published literature reports that the use of NSAIDs at about 30 weeks of gestation and later in pregnancy may cause premature closure of the fetal ductus arteriosus.
Oligohydramnios/Neonatal Renal Impairment: Published studies and postmarketing reports describe maternal NSAID use at…
🆘 Overdosage ▾
10 OVERDOSAGE Symptoms following acute NSAID overdosages have been typically limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain, which have been generally reversible with supportive care. Gastrointestinal bleeding has occurred. Hypertension, acute renal failure, respiratory depression, and coma have occurred, but were rare [ see Warnings and Precautions (5.1, 5.2, 5.4, 5.6) ].
Manage patients with symptomatic and supportive care following an NSAID overdosage. There are no specific antidotes. Forced diuresis, alkalinization of urine, hemodialysis, or hemoperfusion may not be useful due to high protein binding.
For additional information about overdosage treatment contact a poison control center (1-800-222-1222).
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Diclofenac has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of diclofenac, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Diclofenac is a potent inhibitor of prostaglandin synthesis in vitro.
Diclofenac concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation.
Because diclofenac is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues.
12.2Pharmacodynamics DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% applied to intact skin provides local analgesia by releasing diclofenac epolamine from the topical system into the skin.
12.3Pharmacokinetics Absorption - Adults Following a single application of the DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% on the upper inner arm, peak plasma concentrations of diclofenac (range 0.7 – 6 ng/mL) were noted between 10 – 20 hours of application. Plasma concentrations of diclofenac in the range of 1.3 – 8.8 ng/mL were noted after five days with twice-a-day DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% application. Systemic exposure (AUC) and maximum plasma concentrations of diclofenac, after repeated dosing for four days with DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3%, were lower (<1%) than after a single oral 50-mg diclofenac sodium tablet.
The pharmacokinetics of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% has been tested in healthy volunteers at rest or undergoing moderate exercise (cycling 20 min/h for 12 h at a mean HR of 100.3 bpm). No clinically relevant differences in systemic absorption were observed, with peak plasma concentrations in the range of 2.2 – 8.1 ng/mL while resting, and 2.7 – 7.2 ng/mL during exercise. Absorption – Pediatrics Diclofenac plasma concentration was assessed in pediatric patients 6 years and older at a fixed time point 24-hours after the initial application and at the final visit (Day 3 – 15).
The resulting average concentrations were 1.65 ng/mL and 1.80 ng/mL, respectively, both of which are similar to the values observed in adults. Distribution Diclofenac has a very high affinity (>99%) for human serum albumin. Diclofenac diffuses into and out of the synovial fluid.
Diffusion into the joint occurs when plasma levels are higher than those in the synovial fluid, after which the process reverses, and synovial fluid levels are higher than plasma levels. It is not known whether diffusion into the joint plays a role in the effectiveness of diclofenac. Elimination Metabolism Five diclofenac metabolites have been identified in human plasma and urine.
The metabolites include 4'-hydroxy-, 5-hydroxy-, 3'-hydroxy-, 4',5-dihydroxy- and 3'-hydroxy-4'-methoxy diclofenac. The major diclofenac metabolite, 4'hydroxy-diclofenac, has very weak pharmacologic activity. The formation of 4'-hydroxy diclofenac is primarily mediated by CPY2C9.
Both diclofenac and its oxidative metabolites undergo glucuronidation or sulfation followed by biliary excretion. Acylglucuronidation mediated by UGT2B7 and oxidation mediated by CPY2C8 may also play a role in diclofenac metabolism. CYP3A4 is responsible for the formation of minor metabolites, 5-hydroxy and 3'-hydroxy- diclofenac.
Excretion The plasma elimination half-life of diclofenac after application of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% is approximately 12 hours. Diclofenac is eliminated through metabolism and subsequent urinary and biliary excretion of the glucuronide and the sulfate conjugates of the metabolites. Little or no free unchanged diclofenac is excreted in the urine.
Approximately 65% of the dose is excreted in the urine and approximately 35% in the bile as conjugates of unchanged diclofenac plus metabolites. Specific Populations The pharmacokinetics…
