What do FAERS reports show?

22,591 reports list methocarbamol among the medicines taken, each a report of something that happened, not proof the medicine caused it; 1,740 are coded as a death and 6,803 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, 6 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.
