[A rare case of hepatotoxicity in geriatrics].

We report a case of hepatotoxicity following the introduction of two drugs to treat a 81 years old man. The presence of liver alterations following the introduction of a new drug must suggest an adverse drug reaction. Manifestations of adverse drug reactions are often non-specific. Thus, the most important problem in assessing adverse drug reactions is establishing whether there is a causal association between the suspected drug and the untoward clinical event. The use of the Naranjo score could help the clinician to assess the probability of a causal relationship between a drug and the suspected adverse drug reaction.
