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 Diclofenac gel is inadvertently ingested.
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. Gastric decontamination and the use of activated charcoal should be considered, especially within a short time of ingestion.
