Summary
Chronic carbamazepine use can shorten the duration and reduce the potency of non-depolarizing neuromuscular blockers. Rapacuronium has been withdrawn from the market, so this is of little current relevance.
What this interaction means in plain words
Carbamazepine and Rapacuronium have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Chronic carbamazepine therapy causes resistance to non-depolarizing blockers, possibly via receptor changes and increased clearance.
What to do
Monitor neuromuscular blockade with a nerve stimulator and give additional doses if needed.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
