Last updated
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Succinylcholine causes a transient potassium release from muscle, and this may be exaggerated in patients already hyperkalemic. Potassium citrate raises the risk of hyperkalemia and associated arrhythmias around anesthesia.
What this interaction means in plain words
Potassium citrate-citric acid and Succinylcholine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Potassium citrate-citric acid belongs to Gastrointestinal Tract; Succinylcholine belongs to Musculoskeletal.
Why it happens
Depolarizing neuromuscular blockade releases intracellular potassium, adding to potassium raised by supplementation.
What to do
Check serum potassium before elective use of succinylcholine in patients on potassium supplements and correct hyperkalemia first. Consider a non-depolarizing agent if potassium is elevated.
