Interaction report

Indian Snakeroot and Desipramine

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Indian Snakeroot interacts with whole categories of medication. Desipramine falls into 3 of those categories, so it can interact with Indian Snakeroot in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 3

Why this applies to Desipramine

Desipramine falls under CNS DEPRESSANTS — the group Indian Snakeroot interacts with.

Theoretically, taking Indian snakeroot might cause additive sedative effects.
Sedation and drowsiness have been reported in clinical trials using Indian snakeroot.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: both desipramine (Norpramin) and Indian snakeroot can make you feel sleepy and slowed down on their own. Desipramine is an active tricyclic antidepressant (not a prodrug), and it already tends to cause drowsiness, dizziness, and that foggy, sedated feeling for some people. Indian snakeroot, which contains reserpine, has its own calming, blood-pressure-lowering effects. Stack them together and those effects can pile up.

So the realistic concern is feeling extra drowsy, lightheaded, or unusually low. This is a theoretical concern based on how these two work, not strong human proof, so don't panic. Still, please check with your pharmacist or doctor before combining them, especially since snakeroot isn't a gentle home remedy.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

2 of 3

Desipramine also falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES.

Theoretically, Indian snakeroot might inhibit CYP2D6 enzymes and reduce the metabolism of CYP2D6 substrates.
Indian snakeroot contains small amounts of the drug yohimbine. In vitro research shows that yohimbine inhibits CYP2D6 enzyme activity.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the situation with these two. Your body relies on a liver enzyme called CYP2D6 to break down and clear desipramine. Indian snakeroot may slow that enzyme down, partly because it carries a little yohimbine, which can block CYP2D6 in lab studies. If desipramine isn't cleared as fast, more of it can linger in your system, and that can mean stronger tricyclic side effects like a dry mouth, constipation, dizziness, a racing or irregular heartbeat, and feeling overly drowsy.

I want to be honest about the strength here: this is mostly theoretical, based on test-tube research, not real patient cases. Still, snakeroot itself lowers blood pressure and can cause depression, so pairing it with an antidepressant deserves a real conversation. Please check with your pharmacist or doctor before combining them.

Moderate

TRICYCLIC ANTIDEPRESSANTS (TCAs)

3 of 3

Desipramine also falls under TRICYCLIC ANTIDEPRESSANTS (TCAs).

Theoretically, concomitant use might alter the effects of Indian snakeroot and increase the risk of adverse effects.
A small clinical study in patients taking TCAs for at least 4 weeks shows that receiving doses of intravenous yohimbine, a constituent of Indian snakeroot, 2.5-20 mg daily for up to 7 days precipitates severe anxiety, agitation, and tremor. Also, concomitant use of TCAs with Indian snakeroot may decrease the effects of other rauwolfia alkaloids.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the situation if you're thinking about pairing Indian snakeroot with your desipramine (Norpramin). Desipramine isn't a prodrug, it works as-is by boosting norepinephrine and other brain chemicals. The tricky part is that this can cut both ways with snakeroot. One concern is that a constituent linked to this plant can trigger severe anxiety, agitation, and even tremor in people already taking a tricyclic. On the flip side, the tricyclic can blunt the blood-pressure-lowering effect of snakeroot's reserpine.

I'll be honest with you: this is a theoretical concern based on how these drugs behave, not strong proof. Still, snakeroot is potent and unpredictable, so please don't combine them without first checking with your doctor or pharmacist.

About Indian Snakeroot

What is Indian Snakeroot?

Indian Snakeroot
  • High blood pressure
  • Anxiety and stress
  • Insomnia
  • Agitation
  • Fever (traditional use)

Indian snakeroot is a traditional Ayurvedic plant that contains reserpine, a compound with real blood-pressure-lowering and sedative effects. Because its potent alkaloids can cause serious side effects like depression and very low blood pressure, it should never be used without medical supervision. It is not a safe or simple home remedy, and many countries restrict its use.
