Nortriptyline (Pamelor) and Ketamine Therapy | Tovani Health
Pamelor (Nortriptyline) — Tricyclic antidepressant (TCA)
Verdict at Tovani Health
Lowest-anticholinergic TCA; sedation and QT are mild but real, serotonin syndrome is not the concern.
Nortriptyline is one of the better-tolerated TCAs alongside KAP. The interaction profile is sedation and modest QT — both milder than amitriptyline. Veraart 2021 (systematic review of ketamine + psychiatric medications including TCAs) found no documented serotonin syndrome at therapeutic ketamine doses, so we have dropped that historical framing. We do not ask patients to stop nortriptyline.
If you take Pamelor regularly and are considering at-home ketamine therapy, the combination is safe with monitoring or dose adjustment. This page covers the brief pharmacologic context and what we do at intake.
How Pamelor interacts with ketamine
Nortriptyline blocks norepinephrine reuptake with less serotonergic activity than amitriptyline. Sedation and QT effects exist but are smaller. Ketamine adds transient sympathetic activation. Ketamine is not meaningfully serotonergic, so the older SS framing does not apply.
What we do at intake
Tell us the dose and whether you take it at bedtime. Baseline EKG if you have a cardiac history or are on other QT agents.

Frequently Asked Questions
Is nortriptyline safer than amitriptyline with ketamine?
Marginally yes on the sedation and anticholinergic axis. Both are workable; we just plan around the medication you are already on.
Ready to find out if at-home ketamine fits your situation?
