1. What Difenadex is and what it is used for

This medicine is a pain reliever belonging to the group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs).

Difenadex is used in adults for the short-term symptomatic treatment of acute pain of mild to moderate intensity, such as muscle or joint pain (e.g., back pain, sprains, and acute injuries), menstrual pain, and toothache.

2. What you need to know before taking Difenadex

Do not take Difenadex

• If you are allergic to dexketoprofen or any of the other components of this medicine (listed in section 6).
• If you are allergic to acetylsalicylic acid or another non-steroidal anti-inflammatory medicine.
• If you have asthma or have suffered from asthma attacks, acute allergic rhinitis (a short period of inflammation of the nasal mucosa), nasal polyps (fleshy growths inside the nose due to allergy), urticaria (skin rash), angioedema (swelling of the face, eyes, lips, or tongue, or difficulty breathing) or wheezing in the chest after taking acetylsalicylic acid (aspirin) or other non-steroidal anti-inflammatory drugs.
• If you have suffered from photoallergic or phototoxic reactions (a special form of redness or sunburn) while taking ketoprofen (a non-steroidal anti-inflammatory drug) or fibrates (medicines used to reduce blood fat levels).
• If you have a peptic ulcer, stomach or intestinal bleeding, or if you have suffered from bleeding, ulceration, or perforation of the stomach or intestine in the past.
• If you have chronic digestive problems (e.g., indigestion, heartburn).
• If you have suffered from stomach or intestinal bleeding or perforation in the past due to the use of non-steroidal anti-inflammatory drugs (NSAIDs) for pain.

• If you have chronic inflammatory bowel disease (Crohn's disease or ulcerative colitis).
• If you have severe heart failure, moderate to severe kidney failure, or severe liver failure.
• If you have bleeding disorders or blood coagulation disorders.
• If you are severely dehydrated (have lost a lot of body fluid) due to vomiting, diarrhea, or insufficient fluid intake.
• If you are in the third trimester of pregnancy or breastfeeding.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Difenadex:

• If you are allergic or have had allergy problems in the past.
• If you have kidney, liver, or heart disease (high blood pressure and/or heart failure), or fluid retention or have suffered from any of these diseases in the past.
• If you are taking diuretics or have insufficient hydration and reduced blood volume due to excessive fluid loss (e.g., due to excessive urination, diarrhea, or vomiting).
• If you have heart problems, a history of strokes, or think you may be at risk of suffering from these disorders (e.g., you have high blood pressure, suffer from diabetes, have high cholesterol, or are a smoker) you should consult your doctor or pharmacist about this treatment. Medicines like Difenadex may be associated with a small increased risk of suffering from heart attacks ("myocardial infarctions") or strokes. Any risk is more likely to occur when high doses and prolonged treatments are used. Do not exceed the recommended dose or treatment duration.
• If you are an elderly patient, you may experience a higher incidence of side effects (see section 4). If these occur, consult your doctor immediately.
• If you are a woman with fertility problems (see section 2, "Pregnancy, breastfeeding, and fertility").
• If you have a blood disorder and blood cell production disorder.
• If you have systemic lupus erythematosus or mixed connective tissue disease (diseases of the immune system that affect connective tissue).
• If you have suffered from chronic inflammatory bowel disease (ulcerative colitis, Crohn's disease) in the past.
• If you have suffered from stomach or intestinal disorders in the past.
• If you have an infection; see the "Infections" heading below.
• If you are taking other medicines that increase the risk of peptic ulcers or bleeding, such as oral corticosteroids, some antidepressants (of the SSRI type, Selective Serotonin Reuptake Inhibitors), agents that prevent blood clot formation such as acetylsalicylic acid (aspirin) or anticoagulants like Warfarin. In these cases, consult your doctor before taking this medicine: it may be that your doctor prescribes an additional medicine to protect your stomach (e.g., misoprostol or other medicines that block the production of stomach acid).
• If you have asthma combined with chronic rhinitis or sinusitis, and/or nasal polyps, as you have a higher risk of being allergic to acetylsalicylic acid and/or NSAIDs than the rest of the population. The administration of this medicine may cause asthma attacks or bronchospasm, particularly in patients allergic to acetylsalicylic acid or NSAIDs.

Infections

Difenadex may hide the signs of an infection, such as fever and pain. Consequently, this medicine may delay the appropriate treatment of the infection, which may increase the risk of complications. This has been observed in bacterial pneumonia and bacterial skin infections related to chickenpox. If you take this medicine while having an infection and the symptoms of the infection persist or worsen, consult a doctor without delay.

Avoid using this medicine if you have chickenpox.

Children and adolescents

This medicine has not been studied in children and adolescents. Therefore, safety and efficacy have not been established, and the medicine should not be used in children and adolescents.

Taking Difenadex with food, drinks, and alcohol

Generally, it is recommended to take the medicine with meals to reduce the possibility of causing stomach disorders (see also section 3, "Method of administration").

The use of NSAIDs in combination with alcohol may worsen the adverse reactions caused by the active ingredient.

Pregnancy, breastfeeding, and fertility

Do not take this medicine during the last three months of pregnancy or during breastfeeding. Difenadex may cause kidney and heart problems in your fetus. It may affect your and your baby's tendency to bleed and delay or prolong labor more than expected. You should not take Difenadex during the first six months of pregnancy unless it is clearly necessary and as indicated by your doctor. If you need treatment during this period or while trying to become pregnant, you should take the minimum dose for the shortest possible time. From the 20th week of pregnancy, Difenadex may cause kidney problems in your fetus if taken for more than a few days, which may cause low levels of amniotic fluid surrounding the baby (oligohydramnios) or constriction of a blood vessel (ductus arteriosus) in the baby's heart. If you need treatment for more than a few days, your doctor may recommend additional checks.

The use of this medicine may impair fertility, so it is not recommended to use it while trying to conceive or while investigating a fertility problem.

Driving and using machines

This medicine may slightly affect your ability to drive and use machines, as it may cause dizziness or drowsiness and visual disturbances as side effects of treatment. If you notice these effects, do not use machines or drive until these symptoms disappear. Ask your doctor for advice.

Difenadex contains saccharose, methyl parahydroxybenzoate, ethanol, and sodium

It may cause allergic reactions (possibly delayed) because it contains methyl parahydroxybenzoate.

This medicine contains saccharose. If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medicine.

This medicine contains 13.8 mg of alcohol (ethanol) in each sachet, which is equivalent to 1.4 mg/ml (0.14% p/v). The amount in 10 ml of this medicine is equivalent to less than 1 ml of beer or wine.

The small amount of alcohol in this medicine does not produce any noticeable effect.

This medicine contains less than 23 mg of sodium (1 mmol) per sachet; it is essentially "sodium-free".

3. How to take Difenadex

Follow exactly the administration instructions of this medicine contained in this leaflet or as indicated by your doctor or pharmacist. In case of doubt, ask your doctor or pharmacist.

The necessary dose of the medicine may vary depending on the type, intensity, and duration of the pain.

The lowest effective dose should be used for the shortest necessary time to relieve symptoms. If you have an infection, consult a doctor without delay if the symptoms (such as fever and pain) persist or worsen (see section 2).

Adults over 18 years

Generally, the recommended dose is 1 sachet (25 mg of dexketoprofen) every 8 hours, not exceeding 3 sachets per day (75 mg).

Elderly patients or patients with kidney or liver failure

If you are an elderly patient or suffer from mild kidney problems or mild to moderate liver problems, it is recommended to start treatment with a maximum of 2 sachets per day (50 mg of dexketoprofen).

In elderly patients, this initial dose may be increased later according to the general recommended dose (75 mg of dexketoprofen) if the medicine has been well tolerated.

You should not use dexketoprofen if you have moderate or severe kidney problems or severe liver problems. Consult your doctor or pharmacist if you are unsure.

Use in children and adolescents

This medicine should not be used in children and adolescents (under 18 years).

Method of administration

The oral solution can be taken directly from the sachet or after pouring the contents into a glass of water. Once the sachet is opened, consume the entire contents.

The medicine can be taken with or without food. Taking the medicine with food helps to reduce the risk of stomach disorders; however, if your pain is more intense and you need faster relief, take the sachet on an empty stomach (at least 15 minutes before any meal or food intake) because it will be absorbed more easily (see section 2, "Taking Difenadex with food, drinks, and alcohol").

Duration of treatment

Treatment should not exceed 4 days. If the pain persists after this period, worsens, or other symptoms appear, you should stop treatment and consult your doctor or pharmacist.

If you take more Difenadex than you should

Consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone 91 562 04 20, indicating the medicine and the amount taken. It is recommended to take the package and leaflet of the medicine to the healthcare professional.

If you forget to take Difenadex

Do not take a double dose to make up for forgotten doses. Take the next dose when scheduled (according to section 3, "How to take Difenadex").

If you have doubts about the use of this medicine, consult your doctor or pharmacist.

4. Possible Adverse Effects

Like all medicines, this medicine can cause adverse effects, although not all people suffer from them.

Possible adverse effects are detailed below according to their frequency.

Since the list is based in part on adverse effects observed with the oral use of tablets, and the oral solution in sachets is absorbed more quickly than tablets, it is possible that the actual frequency of adverse effects (gastrointestinal) may be higher in the oral solution in sachets.

Frequent Adverse Effects(may affect up to 1 in 10 people)

Nausea and/or vomiting, mainly pain in the upper abdominal quadrant, diarrhea, digestive disorders (dyspepsia).

Uncommon Adverse Effects(may affect up to 1 in 100 people)

Rotatory sensation (vertigo), dizziness, drowsiness, sleep disorders, nervousness, headache, palpitations, hot flashes, inflammation of the stomach wall (gastritis), constipation, dry mouth, flatulence, skin rash, fatigue, pain, febrile sensation, and chills, general malaise.

Rare Adverse Effects (may affect up to 1 in 1,000 people)

Peptic ulcer, perforation of peptic ulcer or bleeding (which may manifest with vomiting of blood or black stools), fainting, high blood pressure, slow breathing, fluid retention, and peripheral edema (e.g., swelling of ankles), laryngeal edema, loss of appetite (anorexia), abnormal sensation, pruritic rash, acne, increased sweating, lower back pain, frequent urination, menstrual disorders, prostate disorders, abnormal liver function tests (blood tests), liver cell damage (hepatitis), acute kidney failure.

Very Rare Adverse Effects (may affect up to 1 in 10,000 people)

Anaphylactic reaction (hypersensitivity reaction that can also lead to collapse), ulcers on the skin, mouth, eyes, and genital areas (Stevens-Johnson syndrome and Lyell syndrome), swelling of the face or swelling of the lips and throat (angioedema), difficulty breathing due to narrowing of the airways (bronchospasm), shortness of breath, tachycardia, low blood pressure, pancreatitis, blurred vision, ringing in the ears (tinnitus), sensitive skin, sensitivity to light, itching, kidney problems. Decrease in the number of white blood cells (neutropenia), decrease in the number of platelets (thrombocytopenia).

Inform your doctor immediately if you notice any adverse effect of a gastrointestinal type at the start of treatment (e.g., stomach pain or burning or bleeding), if you have previously suffered from any of these adverse effects due to prolonged treatment with non-steroidal anti-inflammatory drugs, and especially if you are an elderly patient.

Stop taking this medicine immediately if you notice the appearance of a skin rash or any lesion inside the mouth or on the genitals, or any other sign of allergy.

During treatment with non-steroidal anti-inflammatory drugs, cases of fluid retention and swelling (especially in ankles and legs), increased blood pressure, and heart failure have been reported.

Medicines like Difenadex may be associated with a small increased risk of suffering a heart attack ("myocardial infarction") or stroke ("stroke").

In patients with immune system disorders that affect connective tissue (systemic lupus erythematosus or mixed connective tissue disease), non-steroidal anti-inflammatory drugs can rarely cause fever, headache, and neck stiffness.

The most commonly observed adverse effects are of a gastrointestinal type. Peptic ulcers, perforation, or gastrointestinal bleeding may occur, sometimes fatal, especially in elderly patients.

After administration, nausea, vomiting, diarrhea, flatulence, constipation, dyspepsia, abdominal pain, melena, hematemesis, ulcerative stomatitis, worsening of colitis, and Crohn's disease have been reported. Less frequently, inflammation of the stomach wall (gastritis) has been observed.

As with other non-steroidal anti-inflammatory drugs, aseptic meningitis may occur, which can occur predominantly in patients with systemic lupus erythematosus or mixed connective tissue disease, and hematological reactions (purpura, aplastic anemia, and hemolytic anemia, and, more rarely, agranulocytosis and bone marrow hypoplasia).

Reporting of Adverse Effects
