4.1. Therapeutic indications

Short-term symptomatic relief of headache and migraine.

4.2. Posology and method of administration

Undesirable effects may be minimised by using the lowest effective dose for the shortest duration necessary to control symptoms. (See section 4.4).

The lowest effective dose should be used for the shortest duration necessary to relieve symptoms (see section 4.4).

Posology

Adults and adolescents ≥40 kg (12 years of age and above):

Initial dose is 1 or 2 film-coated tablets (342 mg or 684 mg of ibuprofen lysine) and then 1 or 2 film-coated tablets could be taken up to three times a day as required.

Interval between two doses should be at least six hours.

No more than 6 tablets (2052 mg of ibuprofen lysine) should be taken in any 24 hours period.

Adults:

The patient should consult a doctor if symptoms worsen, or if the product is required for more than 5 days (3 days in case of migraine).

Special patient groups

Paediatric population:

Ibuprofen Lysine 342 mg film-coated tablets is not intended for adolescents weighing less than 40 kg or children under 12 years of age.

If in adolescents this medicine is required for more than 3 days, or if symptoms worsen, a doctor should be consulted.

Elderly:

No special dose adjustment is required. Because of the possible undesirable- effect profile (see section 4.4), it is recommended to monitor the elderly particularly carefully.

Renal impairment:

No dose reduction is required in patients with mild to moderate impairment to renal function however caution should be taken (patients with severe renal insufficiency, see section 4.3).

Hepatic impairment (see section 5.2):

No dose reduction is required in patients with mild to moderate impairment to hepatic function however caution should be taken (patients with severe hepatic dysfunction, see section 4.3).

Method of administration

For oral administration and short-term use only.

The tablets should be swallowed whole and taken with a glass of water. The tablets should not be chewed.

It is recommended that patients with sensitive stomach take Ibuprofen Lysine 342 mg film-coated tablets with food.

4.3. Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Patients who have previously shown hypersensitivity reactions (e.g. asthma, rhinitis, angioedema, or urticaria) in response to aspirin (acetylsalicylic acid) or other non-steroidal anti-inflammatory drugs (NSAIDs).

Active or history of recurrent peptic ulcer/haemorrhage (two or more distinct episodes of proven ulceration or bleeding).

History of gastrointestinal bleeding or perforation, related to previous NSAIDs therapy.

Severe heart failure (NYHA Class IV), renal failure or hepatic failure (see section 4.4).

Patients with cerebrovascular or other active bleeding or with bleeding diathesis.

Patients with unclarified blood-formation disturbances.

Patients with severe dehydration (caused by vomiting, diarrhoea or insufficient fluid intake).

Last trimester of pregnancy (see section 4.6).

4.4. Special warnings and precautions for use

Undesirable effects may be minimised by using the lowest effective dose for the shortest duration necessary to control symptoms (see section 4.2 and GI and cardiovascular risks below).

In the event of undesirable effect occurrence the use of medicinal product should be discontinued and patient should contact a doctor.

Caution is required in patients:

• with Systemic lupus erythematosus and mixed connective tissue disease – increased risk of aseptic meningitis (See section 4.8).

• with mild to moderate renal or hepatic impairment

• with congenital disorder of porphyrin metabolism (e.g. acute intermittent porphyria);

• immediately after major surgery

• who have had hypersensitivity or allergic reactions to other substances, as they could be at an increased risk of hypersensitivity reactions with Ibuprofen Lysine 342 mg film-coated tablets

• who suffer from hay fever, nasal polyps or chronic obstructive respiratory disorders, as for them an increased risk of allergic reactions exists. These may present as asthma attacks (so-called analgesic asthma), Quincke's oedema or urticaria.

Elderly

The elderly have an increased frequency of adverse reactions to NSAIDs especially gastrointestinal bleeding and perforation which may be fatal.

Other NSAIDs:

The use of Ibuprofen with concomitant NSAIDs including cyclooxygenase-2 selective inhibitors should be avoided (see section 4.5).

Renal effects:

Renal impairment as renal function may further deteriorate (see sections 4.3 and 4.8).

Particularly in dehydrated adolescents there is a risk of renal dysfunction.

In general, habitual intake of painkillers, particularly a combination of several analgesic substances, may lead to permanent renal damage with the risk of renal failure (analgesic nephropathy). This risk may be increased under physical strain associated with loss of salt and dehydration.

Renal tubular acidosis and hypokalaemia may occur following acute overdose and in patients taking ibuprofen products over long periods at high doses (typically greater than 4 weeks), including doses exceeding the recommended daily dose.

Hepatic effects:

Hepatic dysfunction (see sections 4.3 and 4.8).

Cardiovascular and cerebrovascular effects:

Caution (consultation with doctor or pharmacist) is required prior to starting treatment in patients with a history of hypertension and/or heart failure as fluid retention, hypertension and oedema have been reported in association with NSAID therapy.

Clinical studies suggest that use of ibuprofen, particularly at a high dose (2400 mg/day) may be associated with a small increased risk of arterial thrombotic events (for example myocardial infarction or stroke). Overall, epidemiological studies do not suggest that low dose ibuprofen (e.g. ≤1200 mg/day) is associated with an increased risk of arterial thrombotic events.

Patients with uncontrolled hypertension, congestive heart failure (NYHA II- III), established ischaemic heart disease, peripheral arterial disease, and/or cerebrovascular disease should only be treated with ibuprofen after careful consideration and high doses (2400 mg/day) should be avoided.

Careful consideration should also be exercised before initiating long-term treatment of patients with risk factors for cardiovascular events (e.g. hypertension, hyperlipidaemia, diabetes mellitus, smoking), particularly if high doses of ibuprofen (2400 mg/day) are required.

Cases of Kounis syndrome have been reported in patients treated with ibuprofen lysine. Kounis syndrome has been defined as cardiovascular symptoms secondary to an allergic or hypersensitive reaction associated with constriction of coronary arteries and potentially leading to myocardial infarction.

Gastrointestinal:

NSAIDs should be given with care to patients with a history of gastrointestinal disease (ulcerative colitis, Crohn's disease) as these conditions may be exacerbated (see section 4.8).

GI bleeding, ulceration or perforation, which can be fatal has been reported with all NSAIDs at any time during treatment, with or without warning symptoms or a previous history of GI events.

The risk of GI bleeding, ulceration or perforation is higher with increasing NSAID doses, in patients with a history of ulcer, particularly if complicated with haemorrhage or perforation (see section 4.3), and in the elderly. These patients should commence treatment on the lowest dose available.

Combination therapy with protective agents (e.g. misoprostol or proton pump inhibitors) should be considered for these patients, and also for patients requiring concomitant low dose of aspirin (acetylsalicylic acid), or other active substances likely to increase gastrointestinal risk (see below and section 4.5).

Patients with a history of GI toxicity, particularly the elderly, should report any unusual abdominal symptoms (especially GI bleeding) particularly in the initial stages of treatment.

Caution should be advised in patients receiving concomitant medications which could increase the risk of ulceration or bleeding, such as oral corticosteroids, anticoagulants such as warfarin, selective serotonin-reuptake inhibitors or anti-platelet agents such as aspirin (acetylsalicylic acid) (see section 4.5).

When GI bleeding or ulceration occurs in patients receiving ibuprofen, the treatment should be withdrawn.

Respiratory disorders:

Bronchospasm may be precipitated in patients suffering from, or with a previous history of bronchial asthma or allergic disease.

Severe cutaneous adverse reactions (SCARs):

Severe cutaneous adverse reactions (SCARs), including exfoliative dermatitis, erythema multiforme, Stevens-Johnson syndrome (SJS), Toxic Epidermal Necrolysis (TEN), Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS syndrome), and acute generalized exanthematous pustulosis (AGEP), which can be life-threatening or fatal, have been reported in association with the use of ibuprofen lysine (see section 4.8). Most of these reactions occurred within the first month.

If signs and symptoms suggestive of these reactions appear ibuprofen should be withdrawn immediately and an alternative treatment considered (as appropriate).

Exceptionally, varicella can be at the origin of serious cutaneous and soft tissues infectious complications. To date, the contributing role of NSAIDs in the worsening of these infections cannot be ruled out. Thus, it may be advisable to avoid use of Ibuprofen Lysine 342 mg film-coated tablets in case of varicella.

Other information:

Severe acute hypersensitivity reactions (for example anaphylactic shock) are observed very rarely. At the first signs of hypersensitivity reaction after taking Ibuprofen Lysine 342 mg film-coated tablets, therapy must be stopped.

Medically required measures, in line with the symptoms, must be initiated by competent persons.

Ibuprofen, the active substance of Ibuprofen Lysine 342 mg film-coated tablets may temporarily inhibit the blood-platelet function (thrombocyte aggregation). Therefore, it is recommended to monitor patients with coagulation disturbances carefully.

In prolonged administration of Ibuprofen Lysine 342 mg film-coated tablets regular control of liver function tests, the kidney function, as well as of the blood count is required.

Prolonged use of any type of painkiller for headaches can make them worse. If this situation is experienced or suspected, medical advice should be obtained and treatment should be discontinued. The diagnosis of medication overuse headache (MOH) should be suspected in patients who have frequent or daily headaches despite (or because of) the regular use of headache medications.

NSAIDs may mask symptoms of infection and fever.

NSAIDs may cause visual disorders. If this happens patients should discontinue the use of the medicinal product and undergo ophthalmic examination.

Concomitant use of NSAIDs and alcohol may increase the occurrence of undesirable effects associated with the medicinal product, particularly those that concern the gastrointestinal tract or the central nervous system.

Masking of symptoms of underlying infections

Ibuprofen lysine can mask symptoms of infection, which may lead to delayed initiation of appropriate treatment and thereby worsening the outcome of the infection. This has been observed in bacterial community acquired pneumonia and bacterial complications to varicella. When Ibuprofen lysine is administered for fever or pain relief in relation to infection, monitoring of infection is advised. In nonhospital settings, the patient should consult a doctor if symptoms persist or worsen.

4.5. Interaction with other medicinal products and other forms of interaction

Ibuprofen should be avoided in combination with:

Aspirin (Acetylsalicylic acid): Concomitant administration of ibuprofen and aspirin (acetylsalicylic acid) is not generally recommended because of the potential of increased adverse effects, unless low-dose aspirin (not above 75mg daily)has been advised by a doctor (see section 4.4).

Experimental data suggest that ibuprofen may competitively inhibit the effect of low dose aspirin (acetylsalicylic acid) on platelet aggregation when they are dosed concomitantly. Although there are uncertainties regarding extrapolation of these data to the clinical situation, the possibility that regular, long-term use of ibuprofen may reduce the cardioprotective effect of low-dose acetylsalicylic acid cannot be excluded. No clinically relevant effect is considered to be likely for occasional ibuprofen use (see section 5.1).

Other NSAIDs including cyclooxygenase-2 selective inhibitors: Concomitant use of two or more NSAIDs should be avoided as this may increase the risk of adverse effects (see section 4.4).

Ibuprofen should be used with caution in combination with:

Corticosteroids: as these may increase the risk of gastrointestinal ulceration or bleeding (see Section 4.4).

Diuretics, ACE inhibitors, beta-receptor-blockers and angiotensin-II antagonists: NSAIDs may reduce the effect of diuretics and other antihypertensive medicinal products. In some patients with compromised renal function (e.g. dehydrated patients or elderly patients with compromised renal function) the co-administration of an ACE inhibitor, beta-receptor- blocker or angiotensin-II antagonist and active substances that inhibit cyclo- oxygenase may result in further deterioration of renal function, including possible acute renal failure, which is usually reversible. The above mentioned interactions should be considered in patients using COX-2 selective inhibitors in combination with ACE inhibitors or angiotensin-II receptor antagonists. Therefore, the combination should be administered with caution, especially in the elderly. Patients should be adequately hydrated and consideration should be given to monitoring of renal function after initiation of concomitant therapy, and periodically thereafter. The concomitant administration of Ibuprofen Lysine 342 mg film-coated tablets and potassium-sparing diuretics may lead to hyperkalaemia.

Diuretics can increase the risk of nephrotoxicity of NSAIDs.

Anticoagulants. Based on limited clinical data NSAIDs may enhance the effects of anti-coagulants, such as warfarin (See section 4.4). Therefore, close monitoring of haematological parameters is recommended during the concomitant therapy.

Anti-platelet agents and selective serotonin reuptake inhibitors (SSRIs): increased risk of gastrointestinal bleeding (see section 4.4).

Cardiac glycosides: NSAIDs may exacerbate cardiac failure, reduce GFR and increase plasma glycoside levels.

Digoxin, phenytoin, lithium: The concomitant use of Ibuprofen Lysine 342 mg film-coated tablets with digoxin, phenytoin or lithium preparations may increase serum levels of these drugs. A check of serum-lithium, serum- digoxin and serum-phenytoin levels is not as a rule required on correct use (maximum over 3 days).

Methotrexate: The administration of Ibuprofen Lysine 342 mg film-coated tablets within 24 hours before or after administration of methotrexate may lead to elevated concentrations of methotrexate and an increase in its toxic effect; monitoring of serum methotrexate is recommended.

Probenecid and sulfinpyrazone: Medicinal products that contain probenecid or sulfinpyrazone may delay the excretion of ibuprofen.

Sulphonylureas: Clinical investigations have shown interactions between NSAIDs and antidiabetics (sulphonylureas). Rare cases of hypoglycemia were reported in patients with concomitant use of sulfonylurea and ibuprofen. A check of blood-glucose values is recommended as a precaution on concomitant intake.

Ciclosporin: Increased risk of nephrotoxicity.

Mifepristone: NSAIDs should not be used for 8-12 days after mifepristone administration as NSAIDs can reduce the effect of mifepristone.

Tacrolimus: Possible increased risk of nephrotoxicity when NSAIDs are given with tacrolimus.

Zidovudine: Increased risk of haematological toxicity and prolonged bleeding time when NSAIDs are given with zidovudine.

There is evidence of an increased risk of haemarthrosis and haematoma in HIV (+) haemophiliacs receiving concurrent treatment with zidovudine and ibuprofen.

Quinolone antibiotics: Animal data indicate that NSAIDs can increase the risk of convulsions associated with quinolone antibiotics. Patients taking NSAIDs and quinolones may have an increased risk of developing convulsions.

Herbal extracts: Ginkgo biloba may potentiate the risk of bleeding with NSAIDs.

CYP2C9 inhibitors: Concomitant administration of ibuprofen with CYP2C9 inhibitors may increase the exposure to ibuprofen (CYP2C9 substrate). In a study with voriconazole and fluconazole (CYP2C9 inhibitors), an increased S(+)-ibuprofen exposure by approximately 80 to 100% has been shown.

Reduction of the ibuprofen dose should be considered when potent CYP2C9 inhibitors are administered concomitantly, particularly when high-dose ibuprofen is administered with either voriconazole or fluconazole.

4.6. Fertility, pregnancy and lactation

No specific studies have been conducted with ibuprofen lysine.

Pregnancy:

Inhibition of prostaglandin synthesis may adversely affect the pregnancy and/or the embryo/foetal development.

Data from epidemiological studies suggest an increased risk of miscarriage and of cardiac malformation and gastroschisis after use of a prostaglandin synthesis inhibitor in early pregnancy. The absolute risk for cardiovascular malformation was increased from less than 1%, up to approximately 1.5%. The risk is believed to increase with dose and duration of therapy.

In animals, administration of a prostaglandin synthesis inhibitor has been shown to result in increased pre- and post-implantation loss and embryofoetal lethality. In addition, increased incidences of various malformations, including cardiovascular, have been reported in animals given a prostaglandin synthesis inhibitor during the organogenetic period.

From the 20th week of pregnancy onward, ibuprofen lysine use may cause oligohydramnios resulting from foetal renal dysfunction. This may occur shortly after treatment initiation and is usually reversible upon discontinuation. In addition, there have been reports of ductus arteriosus constriction following treatment in the second trimester, most of which resolved after treatment cessation. Therefore, during the first and second trimester of pregnancy, Ibuprofen Lysine should not be given unless clearly necessary. If Ibuprofen Lysine is used by a woman attempting to conceive, or during the first and second trimester of pregnancy, the dose should be kept as low and duration of treatment as short as possible. Antenatal monitoring for oligohydramnios and ductus arteriosus constriction should be considered after exposure to ibuprofen lysine for several days from gestational week 20 onward. ibuprofen lysine should be discontinued if oligohydramnios or ductus arteriosus constriction are found.

During the third trimester of pregnancy, all prostaglandin synthesis inhibitors may expose the foetus to:

• cardiopulmonary toxicity (premature constriction/closure of the ductus arteriosus and pulmonary hypertension);

• renal dysfunction (see above); which may progress to renal failure with oligohydroamniosis;

the mother and the neonate, at the end of the pregnancy, to:

• possible prolongation of bleeding time, an anti-aggregating effect which may occur even at very low doses;

• inhibition of uterine contractions resulting in delayed or prolonged labour.

Consequently, Ibuprofen Lysine is contraindicated during the third trimester of pregnancy (see sections 4.3 and 5.3).

Breast-feeding:

In limited studies ibuprofen and its metabolites appear in breast milk in very low concentrations. Since no harmful effects to infants are known to date, it is usually not necessary to interrupt breast- feeding during short-term use of Ibuprofen Lysine at the recommended doses. In case of high doses or prolonged treatment with the medicinal product, consideration should be given to discontinue breastfeeding.

Fertility:

There is some evidence that drugs which inhibit cyclo-oxygenase / prostaglandin synthesis may cause impairment of female fertility by an effect on ovulation. This is reversible on withdrawal of treatment.

4.7. Effects on ability to drive and use machines

Ibuprofen generally has no or negligible influence on the ability to drive and use machines. However as central nervous undesirable effects such as tiredness and dizziness may occur on use of Ibuprofen Lysine 342 mg film-coated tablets at higher dosage, the ability to react and the ability to take part actively in road traffic and to operate machines may be impaired in isolated cases. This applies to a greater extent in combination with alcohol.

4.8. Undesirable effects

The list of the following undesirable effects comprises all undesirable effects that have become known under treatment with ibuprofen, also those under high-dose long-term therapy in rheumatism patients. The stated frequencies, which extend beyond very rare reports, refer to the short-term use of daily doses up to a maximum of 1200 mg ibuprofen for oral dosage forms.

It should be taken into account that the following undesirable effects are predominantly dose-dependent and vary inter-individually.

The most commonly observed undesirable effects are gastrointestinal in nature. Peptic ulcers, perforation or GI bleeding, sometimes fatal, particularly in the elderly may occur (see section 4.4). Nausea, vomiting, diarrhoea, flatulence, constipation, dyspepsia, abdominal pain, melaena, haematemesis, ulcerative stomatitis, exacerbation of colitis and Crohn's disease (see section 4.4) have been reported following administration. Less frequently, gastritis has been observed. In particular the risk of gastrointestinal bleeding is dependent on the dose range and the duration of treatment.

Oedema, hypertension and cardiac failure have been reported in association with NSAID treatment.

Clinical studies suggest that use of ibuprofen, particularly at a high dose (2400 mg/day) may be associated with a small increased risk of arterial thrombotic events (for example myocardial infarction or stroke) (see section 4.4).

Please note that within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

Very common (≥1/10)

Common (≥1/100 to <1/10)

Frequency

Adverse Events

Infections and infestations

Very rare

Exacerbation of infection-related inflammations (e.g. development of necrotising fasciitis) coinciding with the use of non-steroidal anti-inflammatory drugs has been described. This is possibly associated with the mechanism of action of the non- steroidal anti-inflammatory drugs. If signs of an infection occur or get worse during use of Ibuprofen Lysine 342 mg film- coated tablets, the patient is recommended to go to a doctor without delay. It is to be investigated whether there is an indication for an anti-infective/antibiotic therapy.

Blood and lymphatic system disorders

2 Following use of ibuprofen hypersensitivity reactions have been reported and these may consist of: (a) non-specific allergic reaction and anaphylaxis, (b) respiratory tract disorders including asthma, aggravated asthma, bronchospasm and dyspnoea, or (c) various skin disorders, including rashes of various types, pruritus, urticaria, purpura, angioedema and, more rarely, exfoliative and bullous dermatoses (including toxic epidermal necrolysis, Stevens- Johnson syndrome and erythema multiforme).

3 The pathogenic mechanism of drug-induced aseptic meningitis is not fully understood. However, the available data on NSAID-related aseptic meningitis indicate immune reactions (due to a temporal relationship with drug intake, and disappearance of symptoms after drug discontinuation). The symptoms of aseptic meningitis with neck stiffness, headache, nausea, vomiting, fever or consciousness clouding have been observed under ibuprofen. Patients with autoimmune disorders (SLE, mixed connective-tissue disease) during treatment with ibuprofen (see section 4.4).

4 The most commonly observed adverse events are gastrointestinal in nature

5 sometimes fatal, especially in the elderly.

6 See section 4.4.

7 Especially in long term use, associated with increased serum urea. It also includes papillary necrosis.

8Renal tubular acidosis and hypokalaemia have been reported in the post-marketing setting typically following prolonged use of the ibuprofen component at higher than recommended doses.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store. By reporting side effects you can help provide more information on the safety of this medicine.

4.9. Overdose

Symptoms are unlikely at doses below 100 mg/kg. In children, a single dose of over 400 mg/kg can cause symptoms of overdose. In adults the exact dose that could cause these symptoms has not been established. The half-life of overdose ranges from 1.5 to 3 hours.

Symptoms

Most patients who have ingested clinically important amounts of NSAIDs will develop no more than nausea, vomiting, epigastric pain, or more rarely diarrhoea. Tinnitus, headache, dizziness and gastrointestinal bleeding are also possible. In more serious poisoning, toxicity is seen in the central nervous system, manifesting as drowsiness, occasionally excitation and disorientation or coma. Occasionally patients develop convulsions. In serious poisoning metabolic acidosis may occur and the prothrombin time/INR may be prolonged, probably due to interference with the actions of circulating clotting factors. In serious poisoning hyperkalaemia may occur. Acute renal failure, and liver damage may occur, hypotension, respiratory depression, cyanosis and liver damage may occur. Exacerbation of asthma is possible in asthmatics.

In serious poisoning metabolic acidosis may occur and the prothrombin time/INR may be prolonged, probably due to interference with the actions of circulating clotting factors. Acute renal failure and liver damage may occur. Prolonged use at higher than recommended doses or overdose may result in hypokalaemia and renal tubular acidosis. Symptoms may include reduced level of consciousness and generalised weakness (see section 4.4 and section 4.8).

Management

A specific antidote does not exist. Management should be symptomatic and supportive (restoration of electrolyte balance in blood serum, if necessary) and include the maintenance of a clear airway and monitoring of cardiac and vital signs until stable. Consider oral administration of activated charcoal if the patient presents within 1 hour of ingestion of a potentially toxic amount. If frequent or prolonged, convulsions should be treated with intravenous diazepam or lorazepam. Give ronchodilators should be given to patients with asthma.
