When to Stop Adderall Before Surgery
Adderall (amphetamine/dextroamphetamine) does not need to be stopped before surgery and can be safely continued through the perioperative period. 1, 2
Evidence Supporting Continuation
Direct Clinical Evidence
- A case series of 9 patients on chronic prescription amphetamines (2-10 years duration) who underwent general anesthesia demonstrated safe outcomes without stopping the medication preoperatively. 1
- Procedures ranged from 30 minutes to 4.25 hours, with 6 of 8 patients requiring tracheal intubation, and all maintained cardiovascular stability throughout. 1
- An additional case report documented a patient with 40 years of chronic amphetamine use who underwent two general anesthetics without complications. 2
Theoretical Concerns Are Not Supported by Clinical Data
- While historical anesthesia teaching raised concerns about catecholamine depletion and blunted responses to intraoperative hypotension in chronic amphetamine users, actual clinical experience has not demonstrated these problems. 1, 2
- The authors of the largest case series explicitly concluded that "amphetamine use need not be stopped before surgery and anesthesia." 1
Important Perioperative Considerations
Drug Interaction Awareness
- Concomitant use of amphetamines with serotonergic agents (certain opioids, ondansetron, other serotonergic medications) increases the risk of serotonin syndrome. 3
- The anesthesia team should be informed that the patient takes Adderall so they can monitor for serotonergic drug combinations during the perioperative period. 3
Cardiovascular Monitoring
- Although clinical complications have not been reported, enhanced cardiovascular monitoring is prudent given amphetamines' sympathomimetic effects. 1, 2
- Be prepared to manage potential hemodynamic changes, though the evidence suggests these are uncommon. 1
Common Pitfalls to Avoid
- Do not reflexively discontinue Adderall based on outdated theoretical concerns about catecholamine depletion—the clinical evidence does not support this practice. 1, 2
- Do not confuse legitimate prescription amphetamine use with illicit amphetamine abuse—patients on stable, prescribed doses have demonstrated safe perioperative courses. 1
- Ensure the anesthesia team is aware of all serotonergic medications the patient is taking to avoid inadvertent combinations that could precipitate serotonin syndrome. 3
