Overdose : מינון יתר

4.9 Overdose
Signs and symptoms
The low systemic absorption of topical diclofenac renders overdose very unlikely.
However undesirable effects, similar to those observed following an overdose of diclofenac tablets, can be expected if this medicine is inadvertently ingested (e.g. 1 tube of 50 g contains the equivalent of 1 g diclofenac sodium.) 
Treatment
Management of overdosage with NSAIDs essentially consists of supportive and symptomatic measures. There is no typical clinical picture resulting from diclofenac overdosage. Supportive and symptomatic treatment should be given for complications such as hypotension, renal failure, convulsions, gastro-intestinal irritation, and respiratory depression; specific therapies such as forced diuresis, dialysis or haemoperfusion are probably of no help in eliminating NSAIDs due to their high rate of protein binding and extensive metabolism.
In the event of accidental ingestion, resulting in significant systemic adverse effects, general therapeutic measures normally adopted to treat poisoning with non-steroidal anti-inflammatory medicines should be used. The use of activated charcoal should be considered especially within a short time (within one hour) of ingestion of a toxic dose.
