What does the label list?
From the label: adverse reactionsThe following clinically significant adverse reactions are described elsewhere in the labeling: Aluminum Toxicity [see Warnings and Precautions (5.5) ] Hypomagnesemia [see Warnings and Precautions (5.6) ] Vein Damage and Thrombosis [see Warnings and Precautions (5.7) ] The following adverse reactions in Table 5 have been reported in clinical studies or post-marketing reports in patients receiving intravenously administered potassium phosphates. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

What do FAERS reports show?
867 reports list potassium phosphate dibasic and potassium phosphate monobasic among the medicines taken, each a report of something that happened, not proof the medicine caused it; 170 are coded as a death and 511 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 23 reactions below, 4 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.
