Pain-free today, weak tomorrow: a case of electrolyte disorder due to diclofenac misuse

Background: The nephrotoxic effects of non-steroidal anti-inflammatory drugs (NSAIDs) are widely acknowledged. In particular, diclofenac is the most commonly prescribed NSAIDs, but no previous findings of electrolyte disturbances were reported following its administration. Case report: We presented the case of a man who experienced significant weakness associated with severe deficiencies in potassium, calcium, and magnesium after misusing diclofenac because of severe back pain. Conclusions: This case emphasizes the need of awareness about the electrolyte imbalances and electrolyte disturbances associated with the misuse of diclofenac, which is a widely available drug. This is a case report which does not need a Clinical Trial Number.
