Hibiscus Sabdariffa and Esomeprazole Strontium

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

Why Are There 2 Interactions?

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

Minor

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES

1 of 2

Why this applies to Esomeprazole Strontium

Esomeprazole Strontium falls under CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES — the group Hibiscus Sabdariffa interacts with.

Theoretically, Hibiscus sabdariffa extract might reduce the metabolism of CYP2C19 substrates.
In vitro research shows that Hibiscus sabdariffa calyx extract inhibits CYP2C19. This interaction has not been reported in humans.
Severity Minor 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 simple version. Your body uses a liver enzyme called CYP2C19 to help clear esomeprazole (a proton pump inhibitor that lowers stomach acid for heartburn and reflux). In lab dish studies, hibiscus appears to slow that same enzyme down a bit. If that happened in real life, esomeprazole could hang around a little longer and build up slightly, which in theory might mean more of its usual effects, like headache, nausea, or loose stools.

The good news: this is only a theoretical concern based on test-tube data, and it has never actually been reported in people. A cup or two of hibiscus tea is very unlikely to matter. If you take concentrated hibiscus supplements daily, just mention it to your pharmacist or doctor to be safe.

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Esomeprazole Strontium also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, Hibiscus sabdariffa extract might reduce the metabolism of CYP3A4 substrates.
In vitro research shows that Hibiscus sabdariffa calyx extract inhibits CYP3A4. This interaction has not been reported in humans.
Severity Minor 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 gist for your acid reducer (esomeprazole strontium): in lab dish studies, hibiscus appears to slow down an enzyme called CYP3A4, which is one of the pathways that helps your body clear this medicine. In theory, that could let a little more esomeprazole linger in your system. The realistic side effects of this drug are usually mild anyway, things like headache, gas, or some stomach upset.

The big thing I want you to know is how thin this evidence is. This was only seen in a test tube, never in actual people, and it's rated minor. A cup of tart hibiscus tea is very unlikely to cause any trouble here. If you're using concentrated hibiscus capsules, just mention it to your pharmacist so they can keep an eye on things.

About Hibiscus Sabdariffa

What is Hibiscus Sabdariffa?

Hibiscus Sabdariffa
  • High blood pressure
  • Heart and cholesterol health
  • Digestive upset
  • Antioxidant support
  • Fever and general wellness

Hibiscus sabdariffa is a tart, cranberry-flavored plant most often consumed as a tea, and its best-studied use is for mildly lowering blood pressure. Evidence for other uses is limited, and while hibiscus tea is generally well tolerated in food amounts, concentrated supplements should be used cautiously and avoided in pregnancy. Talk to your pharmacist or doctor before using it for a medical condition.
