Special instructions
General recommendations. unwanted effects can be reduced by administering the lowest effective dose for the shortest time possible to control symptoms.
The use of Diclofenac-Teva with systemic NSAIDs, including selective COX-2 inhibitors, should be avoided due to the lack of any synergistic benefits and the possibility of additional side effects.
Care should be taken when prescribing the preparation to elderly patients. In particular, for elderly patients with poor health and for patients with low body weight, it is recommended to use the minimum effective dose.
As with other NSAIDs, allergic reactions, including anaphylactic / anaphylactoid, may also occur without prior exposure to diclofenac.
Diclofenac sodium, due to its pharmacodynamic properties, can mask the signs and symptoms of infection.
Effects on the digestive system. With the use of all NSAIDs, including diclofenac, cases of gastrointestinal bleeding (vomiting of blood, melena), ulceration or perforation have been reported, which can be fatal and occur at any time during treatment with or without warning symptoms, as well as if there is a history of serious gastrointestinal events. These events usually have more serious consequences in elderly patients. If patients receiving diclofenac experience gastrointestinal bleeding or ulceration, the preparation should be discontinued.
As with all NSAIDs, including diclofenac, close medical supervision is necessary; special caution should be exercised when prescribing diclofenac to patients with symptoms suggestive of gastrointestinal disorders, or with a history of gastric or intestinal ulcers, bleeding or perforation. The risk of gastrointestinal bleeding, ulceration or perforation is higher with increasing doses of NSAIDs, including diclofenac, as well as in patients with a history of ulcers, especially with complications such as bleeding or perforation.
In elderly patients, there is an increased frequency of adverse reactions with the use of NSAIDs, especially such as gastrointestinal bleeding and perforation, which can be fatal.
To reduce the risk of toxic effects on the digestive system in patients with a history of ulcers, especially those with complications such as bleeding or perforation, and in elderly patients, treatment is started and maintained with the minimum effective doses.
For such patients, as well as patients who require the combined use of preparations containing low doses of acetylsalicylic acid or other preparations that are likely to increase the risk of adverse effects on the digestive system, combination therapy with protective preparations should be considered (for example proton pump inhibitors or misoprostol).
Patients with a history of gastrointestinal toxicity, especially the elderly, should report any unusual abdominal symptoms (especially gastrointestinal bleeding). Cautions are also needed for patients receiving combination therapy with preparations that may increase the risk of ulcers or bleeding, such as systemic corticosteroids, anticoagulants (such as warfarin), antithrombotics (such as acetylsalicylic acid), or selective serotonin reuptake inhibitors.
Effects on the liver. When taking the preparationby patients with impaired liver function, careful medical supervision is necessary, since their condition may worsen. As with other NSAIDs, including diclofenac, the level of one or more liver enzymes may be increased. During long-term treatment with Diclofenac-Teva, regular monitoring of liver function is required as a precautionary measure.
If liver dysfunction persists or worsens, if clinical signs or symptoms may be associated with progressive liver disease, or if other manifestations are noted (eg eosinophilia, rash), the use of Diclofenac-Teva should be discontinued.
Diseases such as hepatitis may progress without prodromal symptoms.
Caution is necessary if Diclofenac-Teva is used in patients with hepatic porphyria, due to the likelihood of provoking an attack.
Effects on the kidneys. Since fluid retention and edema have been recorded in the treatment of NSAIDs, including diclofenac, special attention should be paid to patients with impaired cardiac or renal function, a history of hypertension, elderly patients, patients receiving concomitant therapy with diuretics or preparations that significantly affect renal function, and patients with a significant decrease in extracellular fluid volume for any reason, for example, before or after major surgery. In such cases, monitoring of renal function is recommended as a precautionary measure. Discontinuation of therapy usually results in a return to the condition prior to treatment.
Effects on the skin. In connection with the use of NSAIDs, including diclofenac sodium, serious skin reactions (some of them fatal) have been reported extremely rarely, including exfoliative dermatitis, Stevens-Johnson syndrome and toxic epidermal necrolysis. The highest risk of developing these reactions is observed at the beginning of the course of therapy, in most cases during the first month of treatment. The use of the preparation Diclofenac-Teva should be discontinued at the first appearance of a skin rash, mucosal lesions or any other signs of hypersensitivity.
Systemic lupus erythematosus and mixed connective tissue diseases. Patients with systemic lupus erythematosus and mixed connective tissue diseases may be at increased risk of developing aseptic meningitis.
Cardiovascular and cerebrovascular effects. Prescribing diclofenac to patients with significant risk factors for cardiovascular events (eg hypertension, hyperlipidemia, diabetes mellitus, smoking) can only be after a thorough clinical assessment. Since the cardiovascular risks of diclofenac may increase with increasing doses and increasing duration of treatment, it should be used for the shortest possible period and at the lowest effective dose.
The patient's need for diclofenac sodium should be periodically reviewed to reduce the severity of symptoms and the response to therapy should be monitored. Use with caution in patients aged ≥65 years.
For patients with a history of hypertension and / or congestive heart failure of mild to moderate severity, appropriate monitoring and recommendations should be made, since cases of fluid retention and edema have been reported in connection with the use of NSAIDs, including diclofenac.
Clinical studies and epidemiological data indicate that the use of diclofenac, especially in high doses (150 mg / day) for a long time, may be associated with a slight increase in the risk of arterial thrombotic events (for example, myocardial infarction or stroke).
It is not recommended to prescribe diclofenac for patients with uncontrolled hypertension, congestive heart failure, stable coronary artery disease, peripheral arterial disease and / or cerebrovascular disease; if necessary, use is possible only after a careful assessment of the risk / benefit ratio only in a dose of no more than 100 mg / day. A similar assessment should be performed before starting long-term treatment of patients with risk factors for cardiovascular events (eg hypertension, hyperlipidemia, diabetes mellitus and smoking).
Patients should be informed about the possibility of serious cases (chest pain, shortness of breath, weakness, speech impairment) that can occur at any time. In this case, you should immediately consult a doctor.
Influence on hematological parameters. With prolonged use of the preparation, like other NSAIDs, monitoring of the blood test is recommended. Like other NSAIDs, Diclofenac-Teva can temporarily inhibit platelet aggregation. Patients with hemostasis disorders, hemorrhagic diathesis or hematological disorders should be closely monitored.
History of asthma. Patients with AD, seasonal allergic rhinitis, patients with swelling of the nasal mucosa (nasal polyps), COPD, or chronic respiratory tract infections (especially those associated with allergic, rhinitis-like symptoms) are more likely than others to have exacerbation-like NSAID reactions AD (so-called intolerance to analgesics / analgesic asthma), Quincke's edema or urticaria. In this regard, such patients are recommended special precautions (readiness to provide emergency care). This also applies to patients with allergies to other substances, manifested by skin reactions, itching or hives.
Like other preparations that suppress the activity of prostaglandin synthetase, diclofenac sodium can provoke the development of bronchospasm in patients with asthma or in patients with a history of asthma.
Fertility in women. The use of the preparation Diclofenac-Teva can lead to impaired fertility in women and is not recommended for women who seek to become pregnant. Consideration should be given to discontinuing the preparation in women who may have difficulty conceiving or undergoing screening for infertility.
IM injection. The instructions for injection must be strictly followed to prevent adverse events at the injection site, which can lead to muscle weakness, muscle paralysis, hypesthesia and necrosis at the injection site.
Children. Diclofenac in the form of an injection solution should not be administered to premature babies or newborns. The use of benzyl alcohol can lead to toxic and anaphylactoid reactions in children under 3 years of age.
Pregnancy. In the first and second trimester of pregnancy, the preparation Diclofenac-Teva can be prescribed only if the expected benefit to the mother exceeds the potential risk to the fetus, only in the minimum effective dose. The duration of treatment should be as short as possible.
Like other NSAIDs, the preparation is contraindicated in the third trimester of pregnancy (possibly suppression of uterine contractility and premature closure of the ductus arteriosus in the fetus).
Inhibition of prostaglandin synthesis can adversely affect pregnancy and / or embryo / fetal development. Epidemiological data indicate an increased risk of miscarriage and / or the risk of developing heart defects and gastroschisis after using an inhibitor of prostaglandin synthesis in early pregnancy. The absolute risk of cardiovascular disease rises from less than 1% to about 1.5%.
It is possible that the risk increases with the dose and duration of treatment. It has been shown that in animals the administration of an inhibitor of prostaglandin synthesis leads to an increase in pre- and post-implantation loss and mortality of the embryo / fetus.
In addition, in animals that received an inhibitor of prostaglandin synthesis during the period of organogenesis, an increased frequency of various malformations was recorded, including those of the cardiovascular system. If Diclofenac-Teva is used in women seeking to become pregnant, or in the first trimester of pregnancy, the dose of the preparation should be as low as possible, and the duration of treatment should be as short as possible.
During the third trimester of pregnancy, all inhibitors of prostaglandin synthesis can affect the fetus as follows:
cardiopulmonary toxicity (with premature closure of the ductus arteriosus and pulmonary hypertension);
impaired renal function, which can progress to renal failure with oligohydroamnion.
The effect of diclofenac on the mother and newborn, as well as at the end of pregnancy:
possible prolongation of bleeding time, antiplatelet effect, which can be observed even at very low doses;
inhibition of uterine contractions, which leads to a delay or lengthening of labor.
Thus, the preparation is contraindicated in the third trimester of pregnancy.
Breastfeeding period. Like other NSAIDs, diclofenac is excreted in breast milk in small amounts. Thus, in order to avoid undesirable effects on the infant, the preparation should not be used during breastfeeding.
Fertility Like other NSAIDs, diclofenac sodium can affect a woman's fertility. The preparation is not recommended for women planning to become pregnant. Women with problems with conception or undergoing tests for infertility should stop using the preparation.
Children. Not intended for use in children.
The ability to influence the reaction rate when driving or working with other mechanisms. Patients who, during treatment with Diclofenac-Teva, experience visual impairment, dizziness, vertigo, drowsiness or other disorders of the central nervous system, should refrain from driving vehicles and working with other mechanisms.
Interactions
Such interactions between the diclofenac-teva preparation and / or other diclofenac preparations may be observed.
Lithium. If used simultaneously, diclofenac can increase the concentration of lithium in the blood plasma. Monitoring of plasma lithium levels is recommended.
Digoxin. If used simultaneously, diclofenac can increase the concentration of digoxin in the blood plasma. Monitoring of plasma digoxin levels is recommended.
Diuretics and antihypertensive preparations. The simultaneous use of diclofenac, like other NSAIDs, with diuretics and antihypertensive agents (for example, β-adrenergic receptor blockers, ACE inhibitors) can lead to a decrease in their antihypertensive effect by inhibiting the synthesis of vasodilating prostaglandins. Therefore, this combination is used with caution, and patients, especially the elderly, should be closely monitored for blood pressure.
Patients should receive adequate hydration, and monitoring of renal function after initiation of concomitant therapy and on a regular basis after it is also recommended, especially with regard to diuretics and ACE inhibitors, due to an increased risk of nephrotoxicity.
Preparations that cause hyperkalemia. Concomitant treatment with potassium-sparing diuretics, cyclosporine, tacrolimus or trimethoprim may be associated with an increase in plasma potassium levels, so patients should be monitored more frequently.
Anticoagulants and antithrombotic agents. It is recommended to take precautions, as the simultaneous administration may increase the risk of bleeding. Although clinical studies do not indicate the effect of diclofenac on the activity of anticoagulants, there are some data on an increased risk of bleeding in patients using simultaneously diclofenac and anticoagulants.
Therefore, to ensure that no changes in anticoagulant dosage are required, careful monitoring of such patients is recommended. Like other NSAIDs, high doses of diclofenac can temporarily suppress platelet aggregation.
Other NSAIDs, including selective COX-2 inhibitors, and GCS. The simultaneous use of diclofenac and other NSAIDs or corticosteroids may increase the risk of gastrointestinal bleeding or ulcers. The simultaneous use of two or more NSAIDs should be avoided.
Selective serotonin reuptake inhibitors. The simultaneous administration of systemic NSAIDs and selective serotonin reuptake inhibitors may increase the risk of gastrointestinal bleeding.
Antidiabetic preparations. Clinical studies have shown that diclofenac can be used together with oral antidiabetic agents without affecting their therapeutic effect. However, there are isolated cases of both hypoglycemic and hyperglycemic effects, requiring a change in the dosage of antidiabetic agents during treatment with diclofenac. In such conditions, monitoring of blood glucose levels is necessary, which is a preventive measure with concomitant therapy.
Methotrexate. Diclofenac can suppress the renal tubular clearance of methotrexate, which leads to an increase in methotrexate levels. When using NSAIDs, including diclofenac, less than 24 hours before treatment with methotrexate, it is recommended to be careful, since the concentration of methotrexate in the blood may increase and the toxicity of this substance may increase. Cases of serious toxicity have been reported when methotrexate and NSAIDs, including diclofenac, were used at intervals within 24 hours. This interaction is mediated due to the accumulation of methotrexate as a result of impaired renal excretion in the presence of NSAIDs.
Cyclosporine. Diclofenac, like other NSAIDs, can increase the nephrotoxicity of cyclosporine due to the effect on renal prostaglandins. Therefore, it should be used at lower doses than for patients not using cyclosporine.
Tacrolimus. When using NSAIDs with tacrolimus, an increased risk of nephrotoxicity is possible, which may be mediated through the renal antiprostaglandin effects of NSAIDs and a calcineurin inhibitor.
Antibacterial quinolones. There are some data on the development of seizures, which may result from the combined use of quinolones and NSAIDs. This can occur in patients with or without a history of epilepsy and seizures. Thus, caution should be exercised when considering the use of quinolones in patients already receiving NSAIDs.
Phenytoin. When using phenytoin simultaneously with diclofenac, it is recommended to monitor the concentration of phenytoin in the blood plasma in connection with the expected increase in phenytoin exposure.
Colestipol and cholestyramine. These preparations may delay or decrease the absorption of diclofenac. Thus, it is recommended to prescribe diclofenac at least 1 hour before or 4–6 hours after the use of colestipol / cholestyramine.
Cardiac glycosides. The simultaneous use of cardiac glycosides and NSAIDs can increase heart failure, reduce the glomerular filtration rate and increase the level of glycosides in the blood plasma.
Mifepristone. NSAIDs should not be used within 8–12 days after using mifepristone, as NSAIDs may reduce its effect.
Potent inhibitors of CYP 2C9. Caution is recommended for the combined administration of diclofenac with potent inhibitors of CYP 2C9 (for example, with voriconazole), which can lead to a significant increase in plasma Cmax and exposure to diclofenac due to inhibition of its metabolism.
Incompatibility. Due to the lack of compatibility studies, this preparation must not be mixed with other preparations.
Overdose
Symptoms the typical clinical symptoms of diclofenac sodium overdose are unknown. in case of overdose, headache, nausea, vomiting, epigastric pain, gastrointestinal bleeding, diarrhea, dizziness, disorientation, agitation, coma, drowsiness, ringing in the ears, loss of consciousness or convulsions may occur. in case of severe poisoning, opn and liver damage are possible.
Treatment. Within 1 hour after the use of a potentially toxic amount of the preparation inside, the use of activated carbon should be considered. In addition, in adults, gastric lavage should be considered within 1 hour after using a potentially toxic amount of the preparation. For frequent or prolonged convulsions, diazepam should be administered intravenously. Taking into account the clinical condition of the patient, other measures may be indicated. Treatment is symptomatic.
