Loss of voice Reaction Insights

33 reports name Loss of voice; 9 recorded a death outcome (27.3% of reported events, not a population-level mortality rate). VeDDRA code: 1267.

Read these counts as reporting volume, not risk: per our methodology, co-reporting reflects temporal association captured in voluntary submissions, not proof that a drug caused this reaction. A widely-prescribed drug will rack up more raw co-reports at an identical true rate than a rarely-used one, so compare within similar-exposure products.
