Interaction report

Wine and Treprostinil (Inh)

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

Why Are There 2 Interactions?

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

Moderate

VASODILATORS

1 of 2

Why this applies to Treprostinil (Inh)

Treprostinil (Inh) falls under VASODILATORS — the group Wine interacts with.

Concomitant use may increase the risk of acute hypotension.
Acute alcohol intoxication can increase the risk of hypotension and additive effects with vasodilators.
Severity Moderate Likelihood Probable Evidence C

Interaction 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..

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: inhaled treprostinil (Tyvaso) is a vasodilator, meaning it relaxes and widens your blood vessels. Wine's alcohol does something similar, and it can lower blood pressure on its own. Put the two together and those effects can stack up, which may drop your blood pressure more than expected.

What that feels like in real life is dizziness, lightheadedness, feeling faint when you stand up, headache, or flushing. This isn't about a sip with dinner for most people, but larger amounts or drinking on an empty stomach raise the risk. Since everyone's situation with PAH is different, please check with your doctor or pharmacist about whether any alcohol is okay for you and how much would be reasonable.

Moderate

ANTIHYPERTENSIVE DRUGS

2 of 2

Treprostinil (Inh) also falls under ANTIHYPERTENSIVE DRUGS.

Theoretically, concomitant use may interfere with blood pressure control.
Clinical research suggests that consumption of alcohol can increase both systolic and diastolic blood pressure. However, acute alcohol intoxication can also increase the risk of hypotension and additive effects with antihypertensive drugs.
Severity Moderate Likelihood Probable Evidence B

Interaction 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..

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

Here's the thing about mixing wine with your inhaled treprostinil (Tyvaso): both can nudge your blood pressure around, just in ways that can work against each other. Treprostinil is a vasodilator, meaning it relaxes and opens up blood vessels. Alcohol has its own push and pull on blood pressure. Over time, regular drinking can actually raise blood pressure and make your PAH treatment work less smoothly. But a single evening of drinking can drop your blood pressure too much, and stacked on top of a vasodilator, that can leave you feeling dizzy, lightheaded, or flushed.

The evidence here is fairly general, not treprostinil-specific, so this isn't a hard 'never.' Still, if you enjoy an occasional glass, please run it by your doctor or pharmacist first so it fits your situation.

From our pharmacist’s overview on the Treprostinil (Inh) page

“Inhaled treprostinil (Tyvaso) relaxes blood vessels in the lungs to treat pulmonary hypertension, and it also blunts platelet clotting, which is why this list of 275 ingredients warrants real vigilance rather than a shrug. Two themes cover almost everything.”

About Wine

What is Wine?

  • Social and relaxation use
  • Heart health (popular belief)
  • Antioxidant intake
  • Aiding digestion (traditional use)
  • Culinary flavoring

Wine is an alcoholic beverage made from fermented grapes and is not a true dietary supplement or medicine. Despite popular claims about heart benefits, the alcohol it contains carries real health risks, and no amount of drinking can be recommended to improve health. If you drink, do so in moderation, and avoid alcohol entirely during pregnancy or if you have certain medical conditions.

About Treprostinil Oral Inhalation

What Is Treprostinil Oral Inhalation Used For?

Brand name: Tyvaso

Treprostinil oral inhalation is used to treat two serious lung conditions that raise pressure in the blood vessels of the lungs. It helps improve how much physical activity you can do.

Tyvaso inhalation solution and Tyvaso DPI are both indicated to treat pulmonary arterial hypertension (PAH; WHO Group 1) and pulmonary hypertension associated with interstitial lung disease (PH-ILD; WHO Group 3). Clinical studies establishing effectiveness in PAH primarily included patients with moderate symptoms (NYHA Class III) whose PAH was idiopathic, heritable, or related to connective tissue disease. Studies in PH-ILD primarily included patients with idiopathic interstitial pneumonia, combined pulmonary fibrosis and emphysema, or connective tissue disease-related lung disease.
