Dosage and directions for use:
Not intended for intravenous injection. Only for deep intragluteal injection into the upper quadrant. Seventy five mg by intramuscular injection once daily or twice daily in severe cases; each injection should be given at a different site. In renal colic the intramuscular dose of 75 mg may be repeated once after 30 minutes if necessary. Diclofenac ampoules should not be given for more than a few (2) days. If necessary, treatment can be continued with oral therapy.
Patients with known hypersensitivity to diclofenac, or other non-steroidal anti-inflammatory medicines. Asthmatic patients in whom attacks of asthma, urticaria or acute rhinitis are precipitated by acetylsalicylicacid, or other medicines with prostaglandin synthetase inhibiting activity. Diclofenac sodium is contra-indicated in patients with a history of active gastro-intestinal bleeding or peptic ulceration, or severe hepatic or renal impairment. Patients with porphyria. Safety during pregnancy and lactation has not been established.
Serious interactions have been reported after the use of methotrexate with diclofenac.
Side-effects and special precautions:
Gastro-intestinal disturbances; reactions range from abdominal discomfort, nausea and vomiting, and abdominal pain to serious gastro-intestinal bleeding or activation of peptic ulcer. CNS-related side-effects include headache, dizziness, nervousness, tinnitus, depression, drowsiness and insomnia. Hypersensitivity reactions may occur occasionally and include fever and rashes. Hepatotoxicity and aseptic meningitis may also be hypersensitivity reactions. It can provoke bronchospasm in patients with asthma. It may cause cystitis and haematuria. It may also cause acute renal failure, interstitial nephritis, and nephrotic syndrome. Other adverse effects include anaemias, thrombocytopenia, neutropenia, eosinophilia, agranulocytosis, abnormalities in liver function tests, blurred vision, changes in visual colour perception, and toxic amblyopia. It should not be given to patients with active peptic ulceration. It should be given with care to the elderly, to patients with asthma or bronchospasm, bleeding disorders, cardio-vascular-disease, a history of peptic ulceration, and in liver or renal failure. Patients with congestive heart failure, cirrhosis, diuretic-induced volume depletion, or renal insufficiency are at greater risk of developing renal dysfunction due to NSAID-induced inhibition of renal prostaglandin synthesis. Care is required in those who are also receiving coumarin anticoagulants. Patients who are sensitive to aspirin or other NSAID's should generally not be given diclofenac. Diclofenac should be discontinued in patients who experience blurred or diminished vision, or changes in colour vision. Patients with collagen disease may be at increased risk of developing aseptic meningitis. In view of the product's inherent potential to cause fluid retention, heart failure may be precipitated in some compromised patients. When given together with preparations containing lithium or digoxin, diclofenac sodium may raise their blood concentrations. Patients receiving long-term treatment with diclofenac should have periodic blood counts. Studies have demonstrated a pharmacokinetic inter-action between diclofenac and salicylates when both are co-administered in anti-inflammatory doses.
