Interaction report

Kratom and Rasagiline

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Kratom interacts with whole categories of medication. Rasagiline falls into 2 of those categories, so it can interact with Kratom in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

1 of 2

Why this applies to Rasagiline

Rasagiline falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Kratom interacts with.

Theoretically, kratom might increase the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that kratom extract inhibits the activity of CYP1A2. In one case report, a 63-year-old male presented with possible serotonin syndrome after taking an unknown dose of kratom for up to 3 months along with serotonergic prescription medications bupropion, buspirone, desvenlafaxine, trazodone, and ziprasidone. It was hypothesized that kratom inhibited CYP1A2-mediaed metabolism of ziprasidone which consequently increased systemic exposure to serotonin.
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.

Here's the gist for rasagiline (Azilect). Your liver clears this drug mainly through an enzyme called CYP1A2. Lab studies hint that kratom can slow that same enzyme down. If that happens in real life, rasagiline could build up in your body and hit harder than intended. With rasagiline that might mean more dizziness, trouble sleeping, low blood pressure when you stand, or worsening involuntary movements.

I want to be honest: this concern is theoretical, based on test-tube data, not strong human studies. But rasagiline is an MAO inhibitor, and kratom acts on the brain too, so combining them also raises a separate worry about over-stimulating brain chemicals. Please don't start, stop, or change anything on your own. Run this past your pharmacist or doctor first.

SEROTONERGIC DRUGS

2 of 2

Rasagiline also falls under SEROTONERGIC DRUGS.

Theoretically, taking kratom in combination with serotonergic drugs may increase levels of serotonin, increasing the risk of serotonin syndrome.
A 63-year-old male presented with possible serotonin syndrome after taking an unknown dose of kratom for up to 3 months along with serotonergic prescription medications bupropion, buspirone, desvenlafaxine, trazodone, and ziprasidone. It was hypothesized that kratom inhibited the cytochrome P450 3A4-, 2C9-, 2D6-, and 1A2-mediated metabolism of several of these serotonergic medications, consequently increasing systemic exposure to serotonin.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to keep in mind with rasagiline (Azilect). It belongs to a group of Parkinson's medicines that raise certain brain chemicals, and it can nudge serotonin activity in the body. Kratom acts on the brain too and may add to that serotonin effect. When you stack two things that both push serotonin upward, there's a chance of pushing it too far, a state called serotonin syndrome.

This warning is theoretical and rests on weak, anecdotal evidence, so I don't want to scare you. But the signs to watch for are real: agitation, a fast heartbeat, sweating, shivering, muscle twitching, or confusion. Because this combo could matter, please loop in your pharmacist or doctor before mixing them rather than changing anything on your own.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

These ratings are for information only. Never start, stop, or otherwise change your therapy before speaking with your provider.

About Rasagiline

What Is Rasagiline Used For?

Brand name: Azilect

Rasagiline tablets — sold as Azilect, Rasagiline, and Rasagiline mesylate — are approved to treat Parkinson's disease (PD). They can be used on their own (monotherapy) or added to other Parkinson's medications, including levodopa.

When used alongside levodopa, rasagiline helps manage Parkinson's symptoms that are not fully controlled by levodopa alone. Your doctor may adjust your levodopa dose when the two are combined.
