Rocuronium and Phenobarbital Interaction

Monitoring and Dosage Considerations

• Quantitative neuromuscular monitoring is strongly recommended when administering rocuronium to patients on phenobarbital therapy, until a Train-of-Four (TOF) ratio of 0.9 has been obtained to ensure adequate recovery from neuromuscular blockade 1, 2, 3

Alternative Agents and Precautions

• The American Academy of Pediatrics recommends considering the use of a benzylisoquinoline muscle relaxant like cisatracurium or atracurium if concerned about the interaction between rocuronium and phenobarbital 4
• The American Heart Association suggests avoiding the use of succinylcholine as an alternative in patients with conditions causing upregulation of nicotinic acetylcholine receptors due to risk of hyperkalemia 5
