4.4 Special warnings and precautions for use
Patients with congestive heart failure, cirrhosis, diuretic-induced volume depletion or renal insufficiency are at a greater risk of developing renal dysfunction due to non-steroidal anti-inflammatory medicine-induced inhibition of renal prostaglandin synthesis.
It is advisable to perform blood counts in patients undergoing prolonged treatment.
A-LENNON DICLOFENAC should be given with care to patients with cardiovascular disease, bleeding disorders, in those who are receiving coumarin anti-coagulants and in patients with impaired hepatic or renal function.
Should be used with caution in patients with asthma or bronchoconstriction.

4.5 Interactions with other medicines
Serious interactions have been reported after the use of high dose methotrexate with diclofenac.

When given together with preparations containing lithium or digoxin, diclofenac sodium may raise their plasma concentrations.
Concomitant administration of glucocorticoids or other non-steroidal anti-inflammatory agents may aggravate gastro-intestinal side effects.
Concomitant administration with two or more non-steroidal anti-inflammatory agents may promote the occurrence of side effects.

4.8 Undesirable effects
Gastrointestinal disorders, including epigastric pain, eructation, nausea and vomiting may occur. Peptic ulceration and gastrointestinal bleeding have been reported.
Other side effects include vertigo, headache, skin rashes, pruritus, tinnitus, depression, drowsiness, nervousness, insomnia, irritability, agitation, minor hearing disorders, oedema, palpitations, blurred vision and other ocular reactions.
Hypersensitivity reactions may occur and include fever and rashes. Hepatotoxicity and aseptic meningitis which occur less frequently may also be hypersensitivity reactions.

Other adverse effects include anaemia, thrombocytopenia, neutropenia, eosinophilia, agranulocytosis and abnormalities in liver function tests.
Allergic reactions which include angio-oedema, bronchospasm, urticaria and anaphylactic reactions have occurred. Because of the possibility of cross-sensitivity due to structural relationships which exist among non-steroidal anti-inflammatory medicines, acute allergic reactions may be more likely to occur in patients who have exhibited allergic reactions to these compounds.
