Drowsiness	5	14.7	Tramadol	E
			Clonazepam	E
			Metoclopramide	E
			Diazepam	E
			Promethazine	E
Hypoglycemia	4	11.8	Glibenclamide + metformin	E
			Glibenclamide	E
			Insulin	E
Lipothymy	3	8.8	Furosemide + dipyrone + metoclopramide	E
			Propranolol + hydrochlorothiazide	F
			Levothyroxine	E

E = temporary harm to the patient and the need for intervention, F = temporary harm to the patient and the need for hospitalization or prolongation of hospitalization, I = death

^aThe number of cases does not match the number of rows in the “ Medications implicated” column because there are repeated EAM-drug pairs (dipyrone-nausea = 2 instances hypoglycemia-glibenclamide + metformin = 2 cases, and hemorrhage-enoxaparin = 2 cases).
