Adverse Reactions
Flushing, sweating, hypotension, hypothermia, respiratory depression, hypocalcemia, circulatory collapse,
cardiac depression, CNS depression
Precautions
Use caution on renal impairment patients because drug is solely removed by the kidneys. Clinical indications of
a safe dosage regimen include the presence of the patellar reflex (knee jerk) and absence of respiratory
depression. When barbiturates, narcotics, or other hypnotics are given in conjunction with magnesium, their
dosage should be adjusted because of the additive central depressive effects. Use caution in patients receiving
digitalis. Stop infusion if hypotension develops, difficulty breathing, decreased deep tendon reflexes, or
paralysis.
Considerations
Not compatible with sodium bicarbonate.
