Interaction report

Kiwi and Selexipag

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

Why Are There 2 Interactions?

Kiwi interacts with whole categories of medication. Selexipag falls into 2 of those categories, so it can interact with Kiwi 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 Kiwi interacts with.

Clinical research suggests that consuming kiwi reduces systolic and diastolic blood pressure in hypertensive individuals. Theoretically, concomitant use of kiwi and antihypertensive drugs may increase the risk of hypotension when used in combination with drugs that lower blood pressure. These include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.
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: kiwi has been shown in some studies to gently lower blood pressure in people who already run high. Selexipag (Uptravi) isn't a typical blood pressure pill, but it works by relaxing the blood vessels in your lungs, and it can lower blood pressure as a side effect too. So in theory, pairing the two could nudge your pressure down a little more than expected.

If that happens, you might feel lightheaded, dizzy, or shaky standing up. That said, this is a theoretical concern based on how things work, not strong proof, and a kiwi or two as food is very unlikely to cause trouble. Concentrated kiwi supplements are more of a question mark. If you're starting one, just give your pharmacist or doctor a heads-up.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Selexipag also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Clinical research suggests that kiwi inhibits platelet aggregation. Theoretically, kiwi might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs. Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

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

Here's the honest picture: the interaction in our database lumps Selexipag (Uptravi) in with blood thinners, but Selexipag isn't really an anticoagulant or antiplatelet drug. It's a medication that relaxes the blood vessels in your lungs to treat pulmonary arterial hypertension. So the bleeding concern they list with kiwi doesn't line up cleanly with how Selexipag actually works.

That said, kiwi has been shown in lab research to mildly slow platelets from clumping, and that finding is theoretical, not proven in people taking real medications. Eating kiwi as a normal food is very unlikely to cause a problem. If you're using concentrated kiwi supplements, or you notice easy bruising or bleeding, just check in with your pharmacist or doctor first.

About Kiwi

What is Kiwi?

  • Constipation and digestive health
  • Vitamin C and antioxidant support
  • Sleep support
  • Immune support
  • Heart and cholesterol health

Kiwi is a nutritious fruit that is rich in vitamin C, fiber, and antioxidants, and it is generally safe to eat as a food. The strongest evidence is for helping with constipation and overall digestive regularity, while other uses like better sleep or immune support are far less proven. People with a known kiwi or latex allergy should avoid it.
