Interaction report

Hesperidin and Treprostinil

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

Why Are There 2 Interactions?

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

Treprostinil falls under ANTIHYPERTENSIVE DRUGS — the group Hesperidin interacts with.

Theoretically, taking hesperidin with antihypertensive drugs might increase the risk of hypotension.
Some clinical and animal research shows that hesperidin can decrease blood pressure. However, other clinical research shows that hesperidin does not affect blood pressure.
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

Treprostinil (Orenitram) widens blood vessels to ease the workload on your heart and lungs in pulmonary hypertension. One of its built-in effects is lowering blood pressure, which is why dizziness, lightheadedness, flushing, and headache are common with it. The concern here is that hesperidin may, in some studies, nudge blood pressure down a little too. Stacked together, the worry is your pressure could dip lower than intended.

I want to be honest about how shaky this evidence is. It is theoretical, and even the human studies disagree, with several showing no real blood pressure effect at all. Occasional citrus in your diet is very unlikely to matter. If you take concentrated hesperidin supplements, just mention it to your pharmacist or doctor and watch for feeling faint when standing.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Treprostinil also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Theoretically, hesperidin may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Animal research suggests that hesperetin, a bioflavonoid aglycone derivative of hesperidin, may have antiplatelet 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 thing worth knowing if you're taking Treprostinil (Orenitram) for pulmonary hypertension. Treprostinil already affects platelets, the tiny cells that help your blood clot, so it can make bleeding a little more likely on its own. Hesperidin, a citrus flavonoid, may have its own mild blood-thinning, anti-platelet effect, so stacking the two together could theoretically nudge your bleeding risk up a bit more.

I want to be honest about how soft this evidence is. This concern comes mostly from animal and lab studies, not from real-world cases, so it's theoretical. Eating a normal amount of oranges almost certainly won't matter; a concentrated hesperidin supplement is where I'd pause. Watch for easy bruising, nosebleeds, or bleeding gums, and check with your pharmacist or doctor before adding it.

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

About Hesperidin

What is Hesperidin?

Hesperidin
  • Hemorrhoids
  • Varicose veins and poor circulation
  • Leg swelling (venous insufficiency)
  • High blood pressure
  • Antioxidant support

Hesperidin is a flavonoid found in citrus fruits that is often combined with diosmin and used for vein and circulation problems like hemorrhoids and varicose veins. Some evidence supports these uses, but data for many other claims is limited. It is generally well tolerated, but pregnant and breastfeeding people should avoid it because safety has not been established.

About Treprostinil

What Is Treprostinil Used For?

Treprostinil treats pulmonary arterial hypertension (PAH; WHO Group 1) — high blood pressure in the arteries of the lungs. Depending on the product and route, it is used to improve exercise ability, delay disease progression, or reduce symptoms tied to physical activity. Remodulin and treprostinil injection products are also indicated for patients who need to transition away from another PAH medicine called epoprostenol.

Tyvaso, Tyvaso DPI, and Yutrepia (inhaled forms) are additionally approved to treat pulmonary hypertension associated with interstitial lung disease (PH-ILD; WHO Group 3) — lung-pressure problems caused by scarring or inflammation in the lung tissue itself. Orenitram (extended-release oral tablet) is specifically indicated to delay disease progression and improve exercise capacity in PAH.
