Hibiscus Sabdariffa and Levobupivacaine

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. Levobupivacaine 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 1A2 (CYP1A2) SUBSTRATES

1 of 2

Why this applies to Levobupivacaine

Levobupivacaine falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Hibiscus Sabdariffa interacts with.

Theoretically, Hibiscus sabdariffa extract might reduce the metabolism of CYP1A2 substrates.
In vitro research shows that Hibiscus sabdariffa calyx extract inhibits CYP1A2. 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 gist: levobupivacaine (Chirocaine) is a local anesthetic, the kind used to numb an area during surgery or for nerve blocks. Part of how your body clears it relies on a liver enzyme called CYP1A2. In lab dish studies, concentrated hibiscus extract seems to slow that same enzyme down a bit. In theory, that could let a little more of the drug linger, which on paper means a slightly stronger or longer effect.

Honestly, I wouldn't lose sleep over this one. This is purely a test-tube finding and has never actually been seen in real people. Levobupivacaine is also given by a clinician in a controlled setting, not something you dose yourself. A cup of hibiscus tea is very unlikely to matter. Still, if you take concentrated hibiscus supplements, just mention it to your anesthesia team or pharmacist beforehand.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Levobupivacaine 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

Levobupivacaine (Chirocaine) is a local anesthetic, the kind of numbing medicine an anesthesiologist injects during surgery or a procedure. Your liver partly clears it using an enzyme called CYP3A4. Lab studies hint that concentrated hibiscus extract may slow that enzyme down, which in theory could let a bit more of the drug linger in your body. If that happened, you might be slightly more prone to its side effects, like numbness lasting longer, dizziness, or in rare cases heart rhythm or nervous system effects.

Here's the reassuring part: this is only a theoretical concern from test-tube research, never reported in real people, and it's rated minor. A cup of tart hibiscus tea is very unlikely to matter. Still, since this drug is usually given in a medical setting, just mention any hibiscus supplements to your care team beforehand.

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.
