Number of facial paralysis cases (No. of cases) and total number of adverse drug reaction cases (Total No.) reported in the World Health Organization pharmacovigilance database are described. Broad definitions of facial paralysis correspond to the following Medical Dictionary for Regulatory Activities (MedDRA) preferred terms (PTs): facial nerve disorder, facial paralysis, facial paresis, facial spasm, oculofacial paralysis, VIIth nerve injury; narrow definition, only to the facial paralysis PT. CrI indicates credible interval.
