Interaction report

Berberine and Selexipag

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

Why Are There 2 Interactions?

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

Moderate

ANTIHYPERTENSIVE DRUGS

1 of 2

Why this applies to Selexipag

Selexipag falls under ANTIHYPERTENSIVE DRUGS — the group Berberine interacts with.

Theoretically, berberine might have additive effects with antihypertensive drugs.
Animal research suggests that berberine can have hypotensive effects. Also, a clinical study suggests that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone.
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 gist for Uptravi (selexipag): berberine on its own may gently nudge your blood pressure down. Selexipag also works by relaxing and widening blood vessels, so stacking the two could, in theory, lower your blood pressure a bit more than expected. That might show up as lightheadedness, dizziness when you stand up, flushing, headache, or feeling unusually tired.

I want to be honest about the evidence though, this is mostly based on animal studies and a small trial with a different blood pressure drug, not selexipag specifically. So it's a possible, not proven, concern. Berberine is not a prodrug issue here, it just adds a similar effect. Since selexipag is carefully dose-adjusted for your lungs, please check with your pharmacist or doctor before adding berberine.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Selexipag also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Theoretically, berberine might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
In vitro and in vivo research suggest that berberine can inhibit platelet aggregation. Theoretically, berberine might have additive effects when used with anticoagulant and antiplatelet drugs and increase the risk of bleeding.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the honest picture with Uptravi (selexipag) and berberine. The interaction on file actually comes from selexipag being grouped with blood thinners and antiplatelet drugs. The concern is that berberine, in lab and animal studies, seems to make platelets a little less sticky, so pairing it with something that affects clotting could in theory raise bleeding risk.

I'll be straight with you though: this is theoretical and based only on test-tube and animal research, not real patients. Selexipag itself works by relaxing the blood vessels in your lungs, and it isn't a classic blood thinner. So the real-world risk here is likely small. Still, before adding berberine, run it by your pharmacist or doctor, especially if you bruise easily or notice any unusual bleeding.

Severity how clinically significant the interaction is
Major

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

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.
