What does the label list?
From the label: adverse reactionsThe most frequent adverse reaction to nondepolarizing blocking agents as a class consists of an extension of the drug's pharmacological action beyond the time period needed. This may vary from skeletal muscle weakness to profound and prolonged skeletal muscle paralysis resulting in respiration insufficiency or apnea. Inadequate reversal of the neuromuscular blockade is possible with vecuronium bromide as with all curariform drugs. These adverse reactions are managed by manual or mechanical ventilation until recovery is judged adequate. Little or no increase in intensity of blockade or duration of action with vecuronium bromide is noted from the use of thiobarbiturates, narcotic analgesics, nitrous oxide, or droperidol.

What do FAERS reports show?
1,526 reports list vecuronium among the medicines taken, each a report of something that happened, not proof the medicine caused it; 230 are coded as a death and 441 as a hospital stay. Counts follow how widely a medicine is used and watched, and they are not a measure of how risky it is. Of the 22 reactions below, 3 are named by the same term (in US spelling) in the label's adverse reactions, warnings or patient leaflet; a reaction the label does not name may still be there under another word, and a report does not show that the medicine caused it.
