Issues for surgery
For treatment of angina/heart failure – exacerbation of symptoms if omitted.
Increased risk of bradycardia if continued.
Advice in the perioperative period
Elective and emergency surgery
Continue – monitor heart rate.
Post-operative advice
Restart post-operatively as soon as next dose is due.
Interactions with common anaesthetic agents
Bradycardia
Ivabradine can increase the risk of bradycardia when used concomitantly with the following:
- alfentanil, fentanyl or remifentanil
- neostigmine
- propofol
- suxamethonium
Interactions with other common medicines used in the perioperative period
Ondansetron
The risk of QT-interval prolongation with concomitant use of ondansetron might be exacerbated by bradycardia caused by ivabradine leading to increased risk of torsades de pointes. The manufacturer of ivabradine advises avoid the combination. If unavoidable monitor cardiac effects (i.e. heart rate) closely.
