Eicosapentaenoic Acid (epa) and Bumetanide

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Bumetanide

Bumetanide falls under ANTIHYPERTENSIVE DRUGS — the group Eicosapentaenoic Acid (epa) interacts with.

Theoretically, taking EPA with antihypertensive drugs might increase the risk of hypotension.
Fish oils containing EPA can lower blood pressure and might have additive effects in patients treated with antihypertensives; use with caution.
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 simple version: bumetanide (Burinex) is a water pill that pulls extra fluid and salt out through your urine, and along the way it can also nudge your blood pressure down. EPA from fish oil tends to gently lower blood pressure too. So when you take them together, those two mild effects can stack up.

For most people this is a small, theoretical concern, and the evidence behind it is on the weaker side. But if your blood pressure drops too low, you might feel dizzy, lightheaded, or wobbly when you stand up, which matters more since bumetanide already makes you lose fluid. Everyday amounts of fish in your diet are unlikely to cause trouble; concentrated EPA supplements are more likely to add up. Talk with your pharmacist or doctor before starting EPA, and let them know if you feel faint.

About Bumetanide

What Is Bumetanide Used For?

Brand name: Burinex

Bumetanide treats edema — excess fluid that builds up in the body — caused by congestive heart failure, hepatic (liver) disease, and renal (kidney) disease, including a condition called nephrotic syndrome. This applies to the oral tablets (bumetanide and Bumex), the injection (Bumetanide Injection), and the nasal spray.

Enbumyst (bumetanide nasal spray) is specifically approved for these same uses in adults. Enbumyst is not intended for long-term use and should be switched to an oral diuretic as soon as practical.
