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) ].

Warnings

Important safety information

Hepatotoxicity : Inform patients of warning signs and symptoms of hepatotoxicity. Discontinue if abnormal liver tests persist or worsen or if clinical signs and symptoms of liver disease develop ( 5.3 ) Hypertension : Patients taking some antihypertensive medications may have impaired response to these therapies when taking NSAIDs. Monitor blood pressure ( 5.4 , 7 ) Heart Failure and Edema: Avoid use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% in patients with severe heart failure unless benefits are expected to outweigh risk of worsening heart failure ( 5.5 ) Renal Toxicity: Monitor renal function in patients with renal or hepatic impairment, heart failure, dehydration, or hypovolemia. Avoid use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% in patients with advanced renal disease unless benefits are expected to outweigh risk of worsening renal function ( 5.6 ) Anaphylactic Reactions : Seek emergency help if an anaphylactic reaction occurs ( 5.7 ) Exacerbation of Asthma Related to Aspirin Sensitivity : DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% is contraindicated in patients with aspirin-sensitive asthma. Monitor patients with preexisting asthma (without aspirin sensitivity) ( 5.8 ) Serious Skin Reactions: Discontinue DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% at first appearance of skin rash or other signs of hypersensitivity ( 5.9 ) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS ): Discontinue and evaluate clinically ( 5.10 ). Fetal Toxicity : Limit use of NSAIDs, including DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3%, between about 20 to 30 weeks in pregnancy due to the risk of oligohydramnios/fetal renal dysfunction. Avoid use of NSAIDs in women at about 30 weeks gestation and later in pregnancy due to the risks of oligohydramnios/fetal renal dysfunction and premature closure of the fetal ductus arteriosus ( 5.11 , 8.1 ). Hematologic Toxicity : Monitor hemoglobin or hematocrit in patients with any signs or symptoms of anemia ( 5.12 , 7 ) 5.1 Cardiovascular 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. 5.2 Gastrointestinal 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 bleed compared to patients without these risk factors. Other factors that increase the risk of GI bleeding in patients treated with NSAIDs include longer duration of NSAID therapy; concomitant use of oral corticosteroids, aspirin, anticoagulants, or selective serotonin reuptake inhibitors (SSRIs); smoking; use of alcohol; older age; and poor general health status. Most postmarketing reports of fatal GI events occurred in elderly or debilitated patients. Additionally, patients with advanced liver disease and/or coagulopathy are at increased risk for GI bleeding. Strategies to Minimize the GI Risks in NSAID-Treated Patients: Use the lowest effective dosage for the shortest possible duration. Avoid administration of more than one NSAID at a time. Avoid use in patients at higher risk unless benefits are expected to outweigh the increased risk of bleeding. For such patients, as well as those with active GI bleeding, consider alternate therapies other than NSAIDs. Remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy. If a serious GI adverse event is suspected, promptly initiate evaluation and treatment, and discontinue DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% until a serious GI adverse event is ruled out. In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, monitor patients more closely for evidence of GI bleeding [ see Drug Interactions (7) ]. 5.3 Hepatotoxicity In clinical trials of oral diclofenac containing products, meaningful elevations (i.e., more than 3 times the ULN) of AST (SGOT) were observed in about 2% of approximately 5,700 patients at some time during diclofenac treatment (ALT was not measured in all studies). In a large open-label, controlled trial of 3,700 patients treated with oral diclofenac sodium for 2-6 months, patients were monitored first at 8 weeks and 1,200 patients were monitored again at 24 weeks. Meaningful elevations of ALT and/or AST occurred in about 4% of the 3,700 patients and included marked elevations (greater than 8 times…

Who should not take Flector

DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% is contraindicated in the following patients: Known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to diclofenac or any components of the drug product [ see Warnings and Precautions (5.7 , 5.9 ) ] History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. Severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients [ see Warnings and Precautions (5.7 , 5.8 ) ] In the setting of coronary artery bypass graft (CABG) surgery [ see Warnings and Precautions (5.1) ] DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% is contraindicated for use on non-intact or damaged skin resulting from any etiology, including exudative dermatitis, eczema, infection lesions, burns or wounds. Known hypersensitivity to diclofenac or any components of the drug product ( 4 ) History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs ( 4 ) In the setting of CABG surgery ( 4 ) For use on non-intact or damaged skin ( 4 )

Overdose — what happens if you take too much

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).

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 minimum lithium concentration increased 15%, and the renal clearance decreased by approximately 20%. This effect has been attributed to NSAID inhibition of renal prostaglandin synthesis. Intervention: During concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and lithium, monitor patients for signs of lithium toxicity. Methotrexate Clinical Impact: Concomitant use of NSAIDs and methotrexate may increase the risk for methotrexate toxicity (e.g., neutropenia, thrombocytopenia, renal dysfunction). Intervention: During concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and methotrexate, monitor patients for methotrexate toxicity. Cyclosporine Clinical Impact: Concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and cyclosporine may increase cyclosporine's nephrotoxicity. Intervention: During concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and cyclosporine, monitor patients for signs of worsening renal function. NSAIDs and Salicylates Clinical Impact: Concomitant use of diclofenac with other NSAIDs or salicylates (e.g., diflunisal, salsalate) increases the risk of GI toxicity, with little or no increase in efficacy [ see Warnings and Precautions (5.2) ] . Intervention: The concomitant use of diclofenac with other NSAIDs or salicylates is not recommended. Pemetrexed Clinical Impact: Concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and pemetrexed may increase the risk of pemetrexed-associated myelosuppression, renal, and GI toxicity (see the pemetrexed prescribing information). Intervention: During concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and pemetrexed, in patients with renal impairment whose creatinine clearance ranges from 45 to 79 mL/min, monitor for myelosuppression, renal and GI toxicity. NSAIDs with short elimination half-lives (e.g., diclofenac, indomethacin) should be avoided for a period of two days before, the day of, and two days following administration of pemetrexed. In the absence of data regarding potential interaction between pemetrexed and NSAIDs with longer half-lives (e.g., meloxicam, nabumetone), patients taking these NSAIDs should interrupt dosing for at least five days before, the day of, and two days following pemetrexed administration. Drugs that Interfere with Hemostasis (e.g. warfarin, aspirin, SSRIs/SNRIs): Monitor patients for bleeding who are concomitantly using DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% with drugs that interfere with hemostasis. Concomitant use of DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% and analgesic doses of aspirin is not generally recommended ( 7 ) ACE Inhibitors, Angiotensin Receptor Blockers (ARB), or Beta-Blockers: Concomitant use with DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% may diminish the antihypertensive effect of these drugs. Monitor blood pressure ( 7 ) ACE Inhibitors and ARBs : Concomitant use with DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% in elderly, volume depleted, or those with renal impairment may result in deterioration of renal function. In such high risk patients, monitor for signs of worsening renal function ( 7 ) Diuretics : NSAIDs can reduce natriuretic effect of furosemide and thiazide diuretics. Monitor patients to assure diuretic efficacy including antihypertensive effects ( 7 ) Digoxin : Concomitant use with DICLOFENAC EPOLAMINE TOPICAL SYSTEM 1.3% may increase serum concentration and prolong half-life of digoxin. Monitor serum digoxin levels ( 7 )

How long does Diclofenac Epolamine stay in your body?

The elimination half-life of diclofenac epolamine is about 2 hours (terminal/elimination half-life; the label's table gives a mean of 2.3 hours in healthy adults, with wide variation between people — 48% coefficient of variation) — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. This is the terminal (elimination) half-life of unchanged diclofenac, as the label labels it — "Terminal Half-life (hr) 2.3" in the PK table, and in the text "the terminal half-life of unchanged diclofenac is approximately 2 hours." Diclofenac is not a prodrug, and it has no active metabolite that outlasts it: the label names five metabolites and says the major one, 4'-hydroxy-diclofenac, has "very weak pharmacologic activity," so the parent's ~2-hour half-life is what governs. (The related diclofenac/misoprostol label notes one additional urinary metabolite with an 80-hour half-life, but it accounts for only ~1.4% of the dose.) Populations the label names: kidney impairment — no dose adjustment for mild-to-moderate impairment; in subjects with inulin clearance 60-90, 30-60 and <30 mL/min, AUC and elimination rate were comparable to healthy subjects. Liver impairment — hepatic metabolism accounts for almost 100% of diclofenac elimination, so patients with liver disease may need reduced doses; the label does not give a revised half-life number. This label reports no pharmacokinetic study in older adults or in children; the diclofenac/misoprostol label found no PK differences in subjects aged 66-81 versus younger adults. Half-life describes how the drug leaves plasma. It is not a detection window (metabolites are detectable far longer) and not dosing guidance.

This is general information, not medical advice. It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.

Frequently asked questions

What does Flector treat?
Flector (Diclofenac Epolamine) may be used to treat juvenile arthritis, rheumatoid arthritis, dysmenorrhea, inflammation, keratosis, osteoarthritis, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
How does Flector work?
Flector is a nonsteroidal anti-inflammatory drug. NSAIDs block cyclooxygenase (COX) enzymes that your body uses to make prostaglandins, the chemicals behind pain, swelling, and fever. Lowering prostaglandins eases pain and inflammation and brings down a high temperature.
How is Flector rated?
pharmaranks gives Flector a composite score of 3.6 out of 5, currently based on 1 weighted source (FDA regulatory recall-safety data weighted highest). See our methodology at /how-we-rate.
How much does Flector cost?
Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $146.33 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
Is there a coupon or discount for Flector?
pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Flector. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
