Interaction report

Kratom and Desipramine

These two interact in 5 distinct ways. Each one is explained separately below.

Why Are There 5 Interactions?

Kratom interacts with whole categories of medication. Desipramine falls into 5 of those categories, so it can interact with Kratom in 5 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 5

Why this applies to Desipramine

Desipramine falls under CNS DEPRESSANTS — the group Kratom interacts with.

Theoretically, concomitant use might increase the risk for adverse CNS depressant effects.
Kratom contains mitragynine, a mu-receptor agonist that may cause respiratory depression. Although results from animal research suggest that mitragynine causes less respiratory depression than the CNS depressant codeine, fatalities have been reported for patients who ingested a combination of kratom and O-desmethyltramadol, another mu-receptor agonist. Additionally, observational research suggests that adverse effects such as drowsiness and coma are more likely to occur in individuals taking kratom in combination with agents such as opioids and sedatives. Theoretically, ingesting kratom along with other CNS depressants can increase the risk of adverse effects, including drowsiness, coma, and/or severe or fatal respiratory depression.
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: Desipramine, an older tricyclic antidepressant, has its own sedating, calming effects on your brain. Kratom acts on opioid receptors and can also slow things down. Put them together and those effects can stack up, leaving you more drowsy, foggy, or dizzy than expected. In the worst case, very slowed breathing can become dangerous.

I'll be straight with you: this concern is theoretical, based on how each substance works rather than solid studies on this exact pair. But desipramine already carries risks on its own, and kratom isn't a regulated or proven-safe product. Before mixing the two, please talk it through with your pharmacist or doctor so they can look at your full picture.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

2 of 5

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

Theoretically, kratom might increase the levels and clinical effects of drugs metabolized by CYP2D6.
In vitro research suggests that kratom extract inhibits CYP2D6 enzyme activity. However, human research shows that a single low dose of kratom tea 2 grams does not inhibit CYP2D6 activity. However, this kratom dose is lower than what is normally taken for psychoactive effects. 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 CYP2D6-mediated metabolism of buspirone and consequently increased systemic exposure to serotonin. In another case, a 37-year-old male stable for 15 years on amitriptyline presented with anticholinergic symptoms including xerostomia, dry eyes, and constipation, along with mildly elevated bilirubin and liver enzymes after taking progressively higher doses of up to 14 grams of kratom daily for 12 weeks. It was hypothesized that the adverse effects of amitriptyline were precipitated by CYP2D6 inhibition by kratom.

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

Here's the gist: your body relies on a liver enzyme called CYP2D6 to break down and clear desipramine. Lab studies suggest kratom may slow that same enzyme down. If that happens, desipramine isn't cleared as quickly and its levels can creep up in your system. Since desipramine is a tricyclic antidepressant, higher levels can mean more of its typical side effects, like dry mouth, constipation, blurry vision, dizziness, fast heartbeat, and drowsiness.

I want to be honest about the strength here: this is mostly theoretical, based on lab data plus a few case reports with similar drugs, not solid human proof. Still, tricyclics have a narrow safety margin, and kratom carries its own real risks. Please don't change anything on your own. Loop in your pharmacist or doctor first.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

3 of 5

Desipramine also falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES.

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.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for desipramine: your liver uses an enzyme called CYP1A2 to help clear this medication out of your system. Lab studies suggest kratom may slow that enzyme down. If that happens, desipramine could build up higher than expected, and since it's an active drug (not a prodrug), more of it means stronger effects and more side effects.

With a tricyclic like this, that might show up as a fast or irregular heartbeat, dizziness, dry mouth, constipation, drowsiness, or trouble urinating. Kratom can also add its own sedating and serotonin-related effects on top. To be fair, this is theoretical, based mostly on lab data, not solid human studies. Still, please check with your pharmacist or doctor before mixing the two.

SEROTONERGIC DRUGS

4 of 5

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

Here's the short version on pairing kratom with desipramine. Desipramine is a tricyclic antidepressant that nudges up serotonin and norepinephrine in your brain. Kratom acts on opioid receptors and may also bump up serotonin activity. Put them together and you could, in theory, push serotonin too high, raising the chance of something called serotonin syndrome. Warning signs include agitation, a racing heart, sweating, shivering, muscle twitching, or confusion.

There's a second wrinkle: kratom may slow the liver enzymes (like CYP2D6) that clear desipramine, so the drug could build up. That can mean more dry mouth, drowsiness, constipation, dizziness, or heart-rhythm effects. To be fair, this is mostly theoretical and based on a single case report, so don't panic. Just please loop in your doctor or pharmacist before mixing them.

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES

5 of 5

Desipramine also falls under CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES.

Theoretically, kratom might increase the levels of drugs metabolized by CYP2C19.
In vitro research shows that kratom extract weakly inhibits CYP2C19 enzyme activity.

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

Here's the basic idea with desipramine and kratom. Desipramine is an active drug (not a prodrug), and your body partly clears it using a liver enzyme called CYP2C19. Lab studies suggest kratom can weakly block that enzyme. If it does, desipramine could clear a little more slowly and build up slightly, which might bump up its usual effects, things like dry mouth, constipation, drowsiness, dizziness, or a faster heartbeat.

I want to be honest about how thin this is though. This concern comes only from test-tube research, the inhibition was weak, and it's rated a minor, theoretical interaction. The bigger worry is that both kratom and desipramine can affect your heart rhythm and your alertness. Please loop in your pharmacist or doctor before combining them.
