Summary
Magnesium absorbed from this oral bowel preparation may potentiate neuromuscular blockers, so the effect of succinylcholine may be stronger or longer. Clinical significance is greatest with renal impairment, when absorbed magnesium accumulates.
What this interaction means in plain words
Sodium sulfate / potassium sulfate / magnesium sulfate 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
Magnesium reduces presynaptic acetylcholine release and lowers postsynaptic sensitivity, enhancing neuromuscular blockade.
What to do
Check serum magnesium in patients with renal impairment or recent bowel preparation before anesthesia. Use quantitative neuromuscular monitoring and titrate the dose to effect.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
