Drug-induced Liver injury

Virtually all drugs can cause liver injury. In this case the most recently introduced medication is most likely to be the cause of liver injury, assuming other investigations for chronic liver disease are negative. The prescription drugs to be particularly aware of when assessing a patient with an undiagnosed liver disorder include Augmentin (co-amoxiclav), diclofenac, isoniazid, erythromycin, sodium valproate, amiodarone and phenytoin.
