Taurine and Selexipag

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Selexipag

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

Theoretically, taurine might increase the risk of hypotension when taken with antihypertensive drugs.
Some clinical evidence suggests that taurine can reduce both systolic and diastolic blood pressure.
Severity Moderate Likelihood Probable Evidence D

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 gist for Selexipag (Uptravi). This medicine already works by relaxing the blood vessels in your lungs, and that can nudge your blood pressure down. Taurine, mostly from concentrated supplements rather than the small amounts in food, has shown a mild blood-pressure-lowering effect of its own in some studies. Stacked together, the worry is that your pressure could dip a little lower than expected.

What that might feel like is more dizziness, lightheadedness when you stand up, headache, or flushing, which are already common with Selexipag. This is a theoretical concern based on how each one behaves, not a proven problem, so don't panic. Just give your pharmacist or doctor a heads-up before adding regular taurine so they can keep an eye on things.

Taurine is an amino acid your body makes naturally and that you also get from animal foods.

Talk with your pharmacist or doctor before taking it regularly, especially if you have a health condition or take medications.

About Selexipag

What Is Selexipag Used For?

Brand name: Uptravi

Selexipag tablets are used to treat pulmonary arterial hypertension (PAH, WHO Group I) — a type of high blood pressure in the arteries of the lungs. The goal is to slow the disease from getting worse and to reduce the chances of being hospitalized because of PAH.

Uptravi (selexipag) tablets are approved for both adults and children aged 2 years and older. Uptravi for injection (intravenous) is also available for adult patients who are already on Uptravi tablets but temporarily cannot take medicine by mouth.
