Supplement Naranjo scale:

·  Are there previous conclusive reports on this reaction?

o  Yes (+1) No (0) Do not know/Not measured/Not done (0).

·  Did the adverse events appear after the suspected drug was given?

o  Yes (+2) No (-1) Do not know/Not measured/Not done (0)

·  Did the adverse reaction improve when the drug was discontinued or a specific antagonist was given?

o  Yes (+1) No (0) Do not know/Not measured/Not done (0)

·  Did the adverse reaction appear when the drug was readministered?

o  Yes (+2) No (-1) Do not know/Not measured/Not done (0)

·  Are there alternative causes that could have caused the reaction?

o  Yes (-1) No (+2) Do not know/Not measured/Not done (0). For alternative causes, only infections involving the brain (such as meningitis or encephalitis) were interpreted as “Yes.” Rest were marked as “Do not know/Not measured/Not done,” as active infection could plausibly considered a potential alternative cause for altered mental status

·  Did the reaction reappear when a placebo was given?

o  Yes (-1) No (+1) Do not know/Not measured/Not done (0)

·  Was the drug detected in any body fluid in toxic concentrations?

o  Yes (+1) No (0) Do not know/Not measured/Not done (0)

·  Was the reaction more severe when the dose was increased, or less severe when the dose was decreased?

o  Yes (+1) No (0) Do not know/Not measured/Not done (0)

·  Did the patient have a similar reaction to the same or similar drugs in any previous exposure?

o  Yes (+1) No (0) Do not know/Not measured/Not done (0)

·  Was the adverse event confirmed by any objective evidence?

o  Yes (+1) No (0) Do not know/Not measured/Not done (0). Abnormalities on EEG were not counted as objective evidence because of lack of specificity.
