Side effects may be minimised by using the lowest effective dose for the shortest duration necessary to control symptoms (see section 4.2).
Allergic reactions, including anaphylactic/anaphylactoid reactions, can also occur without previous exposure to MOTIFINE. MOTIFINE may mask the signs and symptoms of infection due to its pharmacodynamic properties.
The use of MOTIFINE with concomitant NSAIDs including cyclo-oxygenase-2 selective inhibitors should be avoided due to the absence of any evidence demonstrating synergistic benefits and the potential for additive undesirable effects (see section 4.5).
Close medical surveillance is required when prescribing MOTIFINE to patients with impaired hepatic function, as their condition may be exacerbated. Treatment with MOTIFINE can be associated with a rise in liver enzymes. During prolonged treatment with MOTIFINE, regular monitoring of hepatic function is indicated as a precautionary measure. If abnormal liver function tests persist or worsen, or if clinical signs or symptoms consistent with liver disease develop, or if other manifestations occur (e.g. eosinophilia, rash), MOTIFINE should be discontinued. Hepatitis may occur without prodromal symptoms. Caution is called for in patients with hepatic porphyria, since it may trigger an attack.
Appropriate monitoring and caution are required in patients with a history of hypertension and/or heart failure as fluid retention and oedema have been reported in association with MOTIFINE therapy. In view of MOTIFINE’s inherent potential to cause fluid retention, heart failure may be precipitated in some compromised patients.
Particular caution is called for in patients with impaired cardiac or renal function, the elderly, patients receiving concomitant treatment with diuretics or medicinal products that can significantly impact renal function, and in those patients with substantial extracellular volume depletion from any cause, e.g. before or after major surgery (see section 4.3). Monitoring of renal function is recommended as a precautionary measure when using MOTIFINE in such cases. Discontinuation of therapy is usually followed by recovery to the pre-treatment state.
The administration of MOTIFINE may cause a dose dependent reduction in prostaglandin formation and precipitate renal failure. Patients at greatest risk of this reaction are those with impaired renal function, cardiac impairment, liver dysfunction, those taking diuretics and the elderly. Renal function should be monitored in these patients (see section 4.3).
Clinical trial and epidemiological data suggest that use of diclofenac, particularly at high dose (150 mg daily) and in long term treatment may be associated with a small increased risk of arterial thrombotic events (for example myocardial infarction or stroke).
Diclofenac treatment for patients with uncontrolled hypertension should be given only after careful consideration.
Caution is required in patients with significant risk factors for cardiovascular events (e.g. hypertension, hyperlipidaemia, diabetes mellitus, smoking) and should only be treated with diclofenac after careful consideration.
As the cardiovascular risks of diclofenac may increase with dose and duration of exposure, the shortest duration possible and the lowest effective daily dose should be used. The patient’s need for symptomatic relief and response to therapy should be re-evaluated periodically.
Elderly patients have an increased frequency of adverse reactions to NSAIDs including MOTIFINE, especially gastrointestinal bleeding and perforation (PUBs) which may be fatal. A reduction in dosage may be required in the elderly, especially the very frail or those with a low body mass
The risk of gastrointestinal perforation, ulceration or bleeding (PUBs) is higher with increasing doses of MOTIFINE, in patients with a history of ulcers, and the elderly.
When gastrointestinal bleeding or ulceration occurs in patients receiving MOTIFINE, treatment with MOTIFINE should be stopped.
MOTIFINE should be given with caution to patients with a history of gastrointestinal disease (e.g. ulcerative colitis, Crohn’s disease, hiatus hernia, gastro-oesophageal reflux disease, angiodysplasia) as the condition may be exacerbated. Strict accuracy of diagnosis and close medical surveillance are imperative in these patients.
Serious skin reactions, some of them fatal, including exfoliative dermatitis, Stevens-Johnson syndrome, and toxic epidermal necrolysis have been reported. MOTIFINE should be discontinued at the first appearance of skin rash, mucosal lesions and any other sign of hypersensitivity.
In patients with asthma, seasonal allergic rhinitis, swelling of the nasal mucosa (i.e. nasal polyps), chronic obstructive pulmonary diseases or chronic infections of the respiratory tract (especially if linked to allergic rhinitis-like symptoms), reactions to NSAIDs, as contained in MOTIFINE, like asthma exacerbations, Quincke’s oedema or urticaria are more frequent than in other patients. Therefore, special precaution is recommended in such patients (readiness for a medical emergency). This is also applicable to patients who are known to be allergic to other substances and have previously presented with skin reactions, pruritus or urticaria.
Serious interactions have been reported after concomitant use of methotrexate and MOTIFINE (see section 4.5).
In patients with systemic lupus erythematosus (SLE) and mixed connective tissue disorders there may be an increased risk of aseptic meningitis (see section 4.8).
Drug reaction with eosinophilia and systemic symptoms (DRESS) has been reported in patients taking NSAIDs such as MOTIFINE. Some of these events have been fatal or life-threatening. DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling. Other clinical manifestations may include hepatitis, nephritis, haematological abnormalities, myocarditis, or myositis. Sometimes symptoms of DRESS may resemble an acute viral infection. Eosinophilia is often present. Because this disorder is variable in its presentation, other organ systems not noted here may be involved. It is important to note that early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident. If such signs or symptoms are present, discontinue MOTIFINE and evaluate the patient immediately.
MOTIFINE can reversibly inhibit platelet aggregation.
The use of two or more NSAIDs concomitantly could result in an increase in side effects.
Increased risk of gastrointestinal perforation, ulceration or bleeding (PUBs).
MOTIFINE may enhance the effects of anti-coagulants such as warfarin. There are reports of an increased risk of haemorrhage in patients receiving concomitant diclofenac and anticoagulants. Close monitoring of such patients is therefore recommended.
Increased risk of gastrointestinal bleeding.
The bioavailability of both MOTIFINE and acetylsalicylic acid may be reduced if used concurrently.
Caution should be exercised if MOTIFINE and methotrexate are administered within 24 hours of each other. MOTIFINE can inhibit the tubular renal clearance of methotrexate thereby increasing methotrexate levels, leading to toxicity.
Reduced diuretic and anti-hypertensive effect may be seen. The combination should be administered with caution, and patients, especially the elderly, should have their blood pressure monitored. Patients should be adequately hydrated and renal function monitored after initiation of concomitant therapy and periodically thereafter, particularly for those patients on diuretics and MOTIFINE, due to the increased risk of nephrotoxicity.
Diuretics can increase the risk of nephrotoxicity of MOTIFINE. Concomitant treatment with potassium-sparing diuretics may be associated with increased serum potassium levels, hence serum potassium should be monitored. Deterioration in renal function has been attributed to the use of MOTIFINE with triamterene.
There have been reports of convulsions which may have been due to concomitant use of quinolone antibiotics and NSAIDs, such as MOTIFINE.
Nephrotoxicity of ciclosporin may be increased by the effects of MOTIFINE on renal prostaglandins.
Decreased elimination of lithium and digoxin may occur, therefore increasing the plasma concentrations if taken with MOTIFINE.
MOTIFINE may exacerbate cardiac failure, reduce GFR (Glomerular Filtration Rate) and increase plasma digoxin levels. Monitoring of serum digoxin levels is recommended.
MOTIFINE should not be used for 8-12 days after mifepristone administration as MOTIFINE can reduce the effect of mifepristone.
Possible increased risk of nephrotoxicity when MOTIFINE is given with tacrolimus.
Increased risk of haematological toxicity when MOTIFINE is given with zidovudine. There is evidence of an increased risk of haemarthrosis and haematoma in HIV haemophiliacs receiving concurrent treatment with zidovudine and ibuprofen.
Monitoring of phenytoin plasma concentrations is recommended due to an expected increase in phenytoin levels.
These medicines can induce a delay or decrease in absorption, therefore, it is recommended that MOTIFINE is administered at least one hour before or 4 to 6 hours after administration of colestipol/cholestyramine.
Caution recommended when co-prescribing MOTIFINE with potent CYP2C9 inhibitors (such as sulfinpyrazone and voriconazole), which could result in a significant increase in peak plasma concentration and exposure to MOTIFINE.
Studies have shown that MOTIFINE can be given together with oral antidiabetic medicines without influencing their clinical effect. However, there have been reports of both hypoglycaemic and hyperglycaemic effects necessitating changes in the dosage of the antidiabetic medicines during treatment with MOTIFINE. Therefore, monitoring of the blood glucose level is recommended as a precautionary measure during concomitant therapy.
MOTIFINE should not be used in pregnancy (see section 4.3).
Inhibition of prostaglandin synthesis may adversely affect the pregnancy and/or the embryo/fetal development. Data from epidemiological studies raise concern about 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 embryo-fetal lethality. In addition, increased incidences of various malformations, including cardiovascular, have been reported in animals given a prostaglandin synthesis inhibitor during the organogenetic period.
Use of nonsteroidal anti-inflammatory drugs during the third trimester of pregnancy, may cause:
The onset of labour may be delayed and its duration increased.
MOTIFINE should not be used by mothers who are breastfeeding their infants (see section 4.3).
The use of MOTIFINE may impair female fertility and is not recommended in women attempting to conceive. In women who have difficulties conceiving or who are undergoing investigations of infertility, withdrawal of MOTIFINE should be considered.
Patients who experience dizziness, drowsiness, fatigue and visual disturbances, vertigo, somnolence or other central nervous system disturbances while taking MOTIFINE, should refrain from driving a vehicle or operating machinery.
