Contraindications

Dexfenia tablets should not be administered in the following cases: - patients with hypersensitivity to the active ingredient, or other NSAIDs, or any of the excipients listed in paragraph 6.1; - patients in which active ingredients to similar action (e.g. acetylsalicylic acid, or other NSAIDs) trigger asthma, bronchospasm, acute rhinitis, or are the cause of nasal polyps, urticaria or angioneurotic edema; - photoallergic or phototoxic reactions known during treatment with ketoprofen or fibres; - patients with history of bleeding or gastrointestinal perforation in relation to previous NSAID therapy; - patients with active peptic ulcer/gastrointestinal hemorrhage or positive anamnesi for bleeding, ulceration or gastrointestinal perforation; - patients with chronic dyspepsia; - patients who have other active bleeding or clotting disorders; - patients with Crohn disease or ulcerative colitis; - patients with severe heart failure; - patients with moderate to severe renal dysfunction (creatiny cleavage ≤ 59 ml/min); - patients with severe impairment of liver function ( Child-Pugh 10-15 Score); - patients with hemorrhagic dialysis and other clotting disorders; - patients with severe dehydration (caused by vomiting, diarrhea or insufficient liquid intake). - during the third trimester of pregnancy and nursing (see paragraph 4.6).

Population

Population Adults Depending on the nature and intensity of pain, the recommended dose is usually 12.5 mg every 4-6 hours or 25 mg every 8 hours. The total daily dose should not exceed 75 mg. Undesirable effects can be minimized with the use of the lowest effective dose for the shortest possible duration of treatment needed to control symptoms (see paragraph 4.4). Dexfenia tablets is not indicated in long-term treatments and treatment should be limited to symptomatic period. Seniors In older patients it is recommended to start therapy at the lower limit of the dosage range (50 mg of total daily dose). The dosage can be increased so as to reach the recommended one for the general population only after a good general tolerance has been established. Epathetic Comprogation Patients with mild to moderate liver impairment should start treatment at reduced doses (50 mg of total daily dose) and should be subjected to strict medical control. Dexfenia tablets should not be used in patients with severe liver impairment (see paragraph 4.3). Renal Compromise In patients with mild renal impairment (cantonance of creatinine 60 - 89 ml/min), the initial dosage must be reduced to 50 mg of total daily dose (see paragraph 4.4). Dexfenia tablets should not be used in patients with mild to severe renal dysfunction (creatiny ≤ 59 ml/min) (see paragraph 4.3). Pediatric population Dexfenia was not studied in children and adolescents. Therefore, safety and effectiveness have not been established and the product should not be used in children and adolescents. Method of administration The tablet must be swallowed with a sufficient amount of liquid (e.g. a glass of water). The concomitant administration of food delays the rate of absorption of the drug (see “Property Pharmacokinetics”), therefore in case of acute pain it is recommended that the administration take place at least 30 minutes before meals.

Conservation

Store at a temperature below 30°C.

Warnings

Use with precaution in patients with history of allergic conditions. Concurrent use of Dexfenia and other NSAIDs, including selective cycloxygenase 2 inhibitors must be avoided. Undesirable effects can be minimized with the use of the lowest effective dose for the shortest possible duration of treatment needed to control symptoms (see paragraph 4.2, and the paragraphs below on gastrointestinal and cardiovascular risks). Gastrointestinal safety Blood, ulceration or gastrointestinal perforation, which can be fatal, have been reported with all NSAIDs in various stages of treatment, with or without warning symptoms or previous history of serious gastrointestinal events. In case of appearance of bleeding or gastrointestinal ulceration in patients in treatment with Dexfenia, treatment must be stopped. The risk of bleeding, ulceration or gastrointestinal perforation increases with the increase of doses of NSAIDs, in patients with history of ulcer, especially if complicated by hemorrhage or perforation (see paragraph 4.3) and in the elderly. Seniors The elderly have a greater frequency of undesirable reactions to the NSAIDs, especially bleeding and gastrointestinal perforation, which can be fatal (see paragraph 4.2). These patients must begin treatment with the lowest possible dose. As with all NSAIDs, before starting treatment with dexketoprofene, you must investigate previous stories of esophagitis, gastritis and/or peptic ulcer and make sure of their total healing. Patients with gastrointestinal symptoms or history of gastrointestinal disorders must be carefully monitored for the appearance of digestive disorders, especially gastrointestinal bleeding. NSAIDs should be given with caution to patients with history of gastrointestinal diseases ( ulcerative colitis, Crohn's disease) as their conditions may be exacerbated (see paragraph 4.8). A therapy combined with protective agents (e.g. misoprostol or protonic pump inhibitors) must be taken into account for these patients, and also for patients taking a low dose acetylsalicylic acid or other drugs that may increase gastrointestinal risk (see below and paragraph 4.5). Patients with history of gastrointestinal toxicity, especially if elderly, must report any unusual abdominal symptoms (especially gastrointestinal bleeding) in particular in the early stages of treatment. Caution is recommended in patients who receive concomitant treatments that may increase the risk of ulceration or bleeding, such as oral corticosteroids, anticoagulants such as warfarin, selective serotonin reuptake inhibitors or anti-aggregating agents such as acetylsalicylic acid (see paragraph 4.5). Renal safety To be used with caution in patients with impairment of kidney function. In these patients, the use of NSAIDs can cause a worsening of kidney function, fluid retention and edema. Caution is also required in patients under diuretic therapy or in patients who may develop hypovolemia, due to an increased risk of nephrotoxicity. During treatment an adequate supply of liquids must be ensured to prevent dehydration and an associated increase in kidney toxicity. Like all NSAIDs, this medicine can cause an increase in azotemia and creatininemia. As with other prostaglandin synthesis inhibitors, it can be associated with adverse effects to the kidney that can lead to glomerular nephritis, interstitial nephritis, kidney papillar necrosis, nephrosic syndrome and acute kidney failure. Older patients tend more easily to have reduced kidney function (see paragraph 4.2). Epathetic safety To be used with caution in patients with impairment of liver function. Like other NSAIDs, the drug may cause slight transient increases in certain hepatic parameters and also significant increases in AST and ALT. In the event of a significant increase in these parameters, the treatment must be stopped. Older patients tend more easily to suffer from reduced liver function (see paragraph 4.2). Cardiovascular and cerebrovascular safety Adequate monitoring and instructions are necessary in patients with history of hypertension and/or mild to moderate heart failure. Special caution is required in patients with history of heart disease, especially those with previous episodes of heart failure. In these patients, there has been an increase in the risk of triggering heart failure, as retention of fluids and edema have been found in association with the NSAIDs. Clinical studies and epidemiological data suggest that the use of some NSAIDs (especially high doses and long-term treatments) may be associated with a modest increase in the risk of arterial thrombotic events (e.g. myocardial infarction or stroke). There is no sufficient data to exclude a similar risk for dexketoprofene. Consequently, patients with uncontrolled hypertension, congestive heart failure, established ischemic cardiopathy, peripheral arterial disease and/or cerebrovascular disease should be treated with dexketoprofen only after careful evaluation. Analogue considerations must be made before starting a long-term treatment in patients with risk factors for cardiovascular diseases (e.g. hypertension, hyperlipidemia, diabetes mellitus, smoking). All non-selective NSAIDs are able to inhibit piastrinic aggregation and prolong bleeding time by inhibiting prostaglandin synthesis. Therefore, the use of dexketoprofen in patients receiving other treatments that interfere with hemostasis, such as warfarin or other cumarinics or eparine is not recommended (see paragraph 4.5). Older patients tend more easily to suffer from reduced cardiovascular function (see paragraph 4.2). Skin reactions Severe skin reactions, some of them fatal, including exfoliative dermatitis, StevensJohnson's syndrome and toxic epidermal necrolysis were reported very rarely in association with the use of NSAIDs. Patients seem to be more at risk of such reactions at the beginning of therapy, as the appearance of reactions occurs in most cases within the first month of treatment. Treatment with Dexfenia must be interrupted by the first appearance of skin rashes, mucosal lesions or any other sign of hypersensitivity. Other information Particular caution is required in patients: - with congenital disorder of porphyrinic metabolism (e.g. intermittent acute porphyria) ; - with dehydration; - immediately after a major surgery. If the doctor considers long-term dexketoprofen therapy necessary, hepatic and kidney function and blood count should be regularly checked. Severe acute reactions of hypersensitivity (anaphylactic shock, for example) have been observed very rarely. The treatment must be stopped at the first signs of severe hypersensitivity following the intake of Dexfenia. Any necessary medical procedure must be initiated by health professionals based on symptoms. Patients with asthma associated with chronic rhinitis, chronic sinusitis, and/or nasal polypoxes have a higher risk of allergy to acetyllic acid and/or NSAIDs than the rest of the population. The administration of this medicinal product may result in asthma or bronchospasm attacks, particularly in allergic to acetylsalicylic acid or NSAIDs (see paragraph 4.3). Exceptionally, chickenpox can be the origin of severe skin infections and light infectious complications of tissues. To date, the contribution of NSAIDs in the worsening of these infections cannot be excluded. Therefore, it is recommended to avoid using Dexfenia in case of chickenpox. Dexfenia should be administered with caution in patients with hematopoietic disorders, systemic lupus erythematous or in the presence of connective tissue pathologies. Masking the symptoms of underlying infections Dexketoprofen can mask the symptoms of infections, which can lead to a delay in the beginning of an appropriate treatment and therefore to a worsening of the infection. This has been observed in bacterial pneumonia acquires in communities and bacterial complications of chickenpox. When dexketoprofen is administered for relief from fever or pain in relation to infection, it is recommended to monitor the infection. In a non-hospital environment, the patient should consult the doctor if symptoms persist or worsen. Pediatric population Safety of use in children and adolescents has not been established. Sodium This medicine contains less than 1 mmol (23 mg) of sodium per tablet coated with film, i.e. essentially ‘without sodium’.

Interactions

The following interactions are characteristics of non-steroidal anti-inflammatory drugs (NSAID) in general: Non-advisable associations: - Other NSAIDs (including selective cycloxygenase-2 inhibitors) and high doses of salicylates (≥ 3 g/die): simultaneous administration of several NSAIDs can increase the risk of gastrointestinal ulcers and bleeding due to a synergistic effect. - Antiagulants: NSAIDs can enhance the effects of anticoagulants such as warfarin (see paragraph 4.4) due to the high bond to plasma proteins of dexketoprofene and the inhibition of pyastrinic function and damage to gastroduodeal mucosa. If the association cannot be avoided, careful clinical observation and monitoring of laboratory parameters must be carried out. Eparine: increased risk of hemorrhage (due to the inhibition of the pyasternic function and the damage to gastroduodenal mucosa). If the association cannot be avoided, careful clinical observation and monitoring of laboratory parameters must be carried out. - Corticosteroids: increased risk of gastrointestinal ulceration or bleeding (see paragraph 4.4). - Lithium (described with several NSAIDs): NSAIDs increase the blood levels of lithium that can reach toxic values (decreate renal excretion of lithium). This parameter therefore requires careful monitoring during the start, adjustment and termination of treatment with dexketoprofene. - Metotrexate, used at high doses such as 15 mg/week or more: increased hematological toxicity of metotrexate due to a decrease in its kidney clearance, caused by anti-inflammatory drugs in general. - Idantoins and sulfonamides: the toxic effects of these substances can be enhanced. Associations requiring caution: - Diuretics, ACE inhibitors, aminoglycosidic antibiotics and antagonists of angiotensin receptor II: dexketoprofen can reduce the effect of diuretics and other antihypertensive drugs. In some patients with reduced kidney function (e.g. dehydrated patients or elderly patients with impaired kidney function), the concomitant administration of agents that inhibit cycloxygenase and ACEinibitors, antagonists of angiotensin receptor II or aminoglycoside antibiotics may cause further deterioration of kidney function, which is usually reversible. In case of combined prescription of dexketoprofen with a diuretic, it is essential to ensure that the patient is properly hydrated and monitor the kidney function at the beginning of the treatment (see paragraph 4.4 Special warnings and precautions). - Metotrexate, used at doses less than 15 mg/week: increased hematological toxicity of metotrexate due to a decrease in its kidney clearance caused by anti-inflammatory drugs generally. It counts weekly blood in the first weeks of the association. Increased surveillance, as well as in the elderly patient, in case of even mild kidney failure. - Pentoxyphylline: increased risk of hemorrhage. Increase clinical monitoring and control bleeding time more frequently. - Zidovudina: risk of increased toxicity on the erythrocyte line due to action on reticulocytes, with occurrence of severe anemia a week after the start of treatment with NSAIDs. Check the complete hemochrome and count of reticulocytes every one or two weeks during treatment with NSAIDs. - Sulphonluree: NSAIDs can increase the hypoglycemic effect of sulphonluree by spying on plasma protein binding sites. Combinations to be considered: - Beta-blockers: treatment with NSAIDs can decrease their antihypertensive effect due to the inhibition of prostaglandin synthesis. - Ciclosporine and tacrolimus: NSAIDs can enhance nephrotoxicity due to the effects mediated by kidney prostaglandins. During association therapy, renal function must be kept under control. - Trombolitics: increased risk of hemorrhage. - Serotonin reuptake selective agents and inhibitors (SSRIs): increased risk of gastrointestinal bleeding (see paragraph 4.4). - Probenecid: it can increase the plasma concentrations of dexketoprofen; this interaction can be due to an inhibitory mechanism at the level of the secretion of the renal tubule and glucuronoconjugation and requires a adjustment of the dose of dexketoprofene. - Cardioactive glycosides: NSAIDs can increase plasma concentrations of glycosides. - Mifepristone: there is the theoretical risk that prostaglandinsintetase inhibitors may alter the effectiveness of mifepristone. Limited evidence suggests that the concomitant administration of NSAIDs on the same day of prostaglandine administration does not adversely affect the effects of mifepristone or prostaglandins on cervical maturation or uterine contractility and does not reduce the clinical effectiveness of the medical interruption of pregnancy. - Chinolonic antibiotics: animal studies indicate that high doses of chinolone in combination with NSAIDs can increase the risk of convulsion occurrence. - Tenofovir: Concurrent use with NSAIDs can increase atathemia and creatinine, so the kidney function must be monitored to control a possible synergistic influence on the kidney function. - Deferasirox: Concurrent use with NSAIDs can increase the risk of gastrointestinal toxicity. When administering deferasirox with these substances it is necessary to carry out rigorous clinical monitoring. - Pemetrexed: Concurrent use with NSAIDs can reduce the elimination of pemetrexed, therefore it is necessary to exercise caution in administering higher doses of NSAIDs; in patients with mild to moderate renal failure (clearance of creatinine between 45 and 79 ml/min), the concomitant administration of pemetrexed with NSAID should be avoided for 2 days before and 2 days after administration.

The most common side effects are gastrointestinal. Peptic ulcers, perforation or gastrointestinal bleeding may be manifested, sometimes fatal, especially in the elderly (see paragraph 4.4). As a result of the administration, nausea, vomiting, diarrhea, flatulence, constipation, dyspepsia, abdominal pain, melena, ematemesis, ulcerative stomatitis, exacerbation of colitis and Crohn's disease (see paragraph 4.4Special warnings and precautions). Less frequently gastritis was observed. In association with NSAID therapy, edema, hypertension and heart failure were reported. As with other NSAIDs, the following side effects may appear: aseptic meningitis, which can occur mainly in patients with systemic erythematous lupus or pathologies dependent on connective tissue; hematological reactions (porpora, aplastic anemia and hemolytics, and rarely agranulocytosis and midollar hypoplasia). Bollose reactions, including Stevens Johnson syndrome and toxic epidermal necrolysis (very rare). Clinical studies and epidemiological data suggest that the use of some NSAIDs (especially high doses and long-term treatments) may be associated with a modest increase in the risk of arterial thrombotic events (e.g. myocardial infarction or stroke) (see paragraph 4.4). Reporting of suspicious adverse reactions The reporting of suspicious adverse reactions that occur after the authorization of the medicinal product is important, as it allows continuous monitoring of the benefit/risk ratio of the medicinal product. Healthcare workers are required to report any suspected adverse reaction via the national reporting system at: https://www.aifa.gov.it/content/segnalazionireazioni-avverse.

Overdosing

Syntomatology following overdose is not known. Similar drugs have produced gastrointestinal disorders (vomite, anorexia, abdominal pain) and neurological disorders (somnolence, dizziness, disorientation, headaches). In case of accidental or excessive intake, immediately take appropriate symptomatic therapy according to the patient’s clinical conditions. Within an hour it is necessary to administer activated charcoal if more than 5 mg/kg were ingested by an adult or child. Dexketoprofene tromethylamolo can be eliminated by dialysis.

- Dexfenia tablets is contraindicated during the third trimester of pregnancy and during lactation. (see paragraph 4.3).

Pregnancy

Inhibition of prostaglandin synthesis can negatively affect pregnancy and/or embryo/fetal development. Results of epidemiological studies suggest an increased risk of abortion and cardiac malformation and gastroschisis after the use of an inhibitor of prostaglandin synthesis in the early stages of pregnancy. The absolute risk of heart failure is increased from less than 1% to about 1.5%. It is believed that the risk increases with dose and duration of therapy. In animals, the administration of prostaglandin synthesis inhibitors showed an increase in pre- and post-system loss and embryo-fetal mortality. In addition, an increase in the incidence of various malformations, including cardiovascular disease, was reported in animals that had been given inhibitors of prostaglandin synthesis during the organogenetic period. However, studies on animals with dexketoprofen did not indicate reproductive toxicity (see paragraph 5.3). During the first and second trimester of pregnancy, dexketoprofen should not be administered if not in strictly necessary cases. If dexketoprofene is used by a woman waiting for conception, or during the first and second trimester of pregnancy, the dose and duration of treatment must be kept as low as possible. During the third trimester of pregnancy, all prostaglandin synthesis inhibitors can expose the fetus to: - cardiopulmonary toxicity (with premature closure of arterial duct and pulmonary hypertension); - kidney dysfunction, which can progress in kidney failure with oligoidramnios; the mother and the newborn, at the end of pregnancy, to: - possible prolongation of bleeding time, an anti-aggregating effect that can occur even at very low doses; - inhibition of uterine contractions resulting in delay or extension of labor.

Food

It is not known whether dexketoprofene is excreted in breast milk. Dexfenia is contraindicated during lactation (see paragraph 4.3).

Fertility

As with other NSAIDs, the use of Dexfenia can reduce female fertility and is not recommended in women who intend to conceive. It is necessary to consider the interruption of treatment with dexketoprofen in women who have difficulties in conception or subject to infertility investigations.
