Summary
Succinylcholine can cause an acute rise in serum potassium, and potassium supplementation adds to the potassium load. In patients with renal impairment or existing hyperkalemia, this may contribute to dangerous arrhythmias.
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.
Why it happens
Additive increases in serum potassium from succinylcholine-induced efflux from muscle and exogenous potassium.
What to do
Check serum potassium before using succinylcholine and correct hyperkalemia first. Consider a non-depolarizing blocker in patients with high potassium or renal impairment.
