Fucus Vesiculosus and Ibuprofen, Hydrocodone

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Fucus Vesiculosus interacts with whole categories of medication. Ibuprofen, Hydrocodone falls into 3 of those categories, so it can interact with Fucus Vesiculosus in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Minor).

Minor

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

1 of 3

Why this applies to Ibuprofen, Hydrocodone

Ibuprofen, Hydrocodone falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Fucus Vesiculosus interacts with.

Theoretically, concomitant use of Fucus vesiculosus with CYP2D6 substrates might alter the effects of these substrates.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, both inhibits and induces CYP2D6. 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 situation with bladderwrack and your ibuprofen/hydrocodone combo. The hydrocodone part is actually a prodrug, meaning your liver has to switch it on (using an enzyme called CYP2D6) to turn some of it into hydromorphone for stronger pain relief. Lab studies suggest a compound in bladderwrack (fucoidan) can both speed up and slow down that same enzyme, so the direction could go either way.

In theory, that might mean slightly weaker pain control or, on the other hand, a bit more drowsiness, dizziness, or constipation. But honestly, this is only test-tube research and has never been seen in real people, so I wouldn't lose sleep over it. Still, it's worth a quick mention to your pharmacist before you combine them.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 3

Ibuprofen, Hydrocodone also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, concomitant use of Fucus vesiculosus with CYP3A4 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, 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 with bladderwrack and your combo pill Ibucodone, which pairs ibuprofen with hydrocodone. In test tube studies, a seaweed compound called fucoidan appears to slow down a liver enzyme (CYP3A4) that helps clear the hydrocodone part of this medicine. In theory, if that enzyme runs slower, hydrocodone could hang around a bit longer and feel stronger, which might mean more drowsiness, dizziness, constipation, or slowed breathing.

I want to be honest, though: this is only lab data, and it has never actually been seen in real patients, so I wouldn't lose sleep over it. The bigger concern with bladderwrack is its heavy iodine load on your thyroid. Before you mix the two, run it by your pharmacist or doctor.

Minor

ANTICOAGULANT/ANTIPLATELET DRUGS

3 of 3

Ibuprofen, Hydrocodone also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Theoretically, taking Fucus vesiculosus with antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
In vitro evidence suggests that a constituent of Fucus vesiculosus, known as fucoidan, has anticoagulant effects. However, in clinical research, fucoidan does not seem to have significant anticoagulant activity when taken orally, possibly due to poor absorption.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the gist for your Ibuprofen and Hydrocodone combo (sold as Ibucodone): the ibuprofen half is an NSAID, and NSAIDs already carry a small risk of stomach upset and bleeding, especially in the gut. Bladderwrack contains a compound called fucoidan that, in lab dish studies, showed some blood-thinning activity. The worry is that stacking the two could nudge your bruising or bleeding risk up a bit.

The reassuring part is that this is very theoretical. When fucoidan is actually swallowed, the body barely absorbs it, so human studies haven't shown real blood-thinning. I wouldn't lose sleep over it, but if you notice easy bruising, dark stools, or stomach pain, or you take this often, check in with your pharmacist or doctor.

About Fucus Vesiculosus

What is Fucus Vesiculosus?

Fucus Vesiculosus
  • Thyroid support
  • Iodine source
  • Weight management
  • Joint and skin care (topical)
  • Constipation and digestive support

Fucus vesiculosus (bladderwrack) is a brown seaweed rich in iodine that has been used traditionally for thyroid concerns, weight, and skin. There is little solid human evidence to support most of these uses, and its high and variable iodine content can actually harm the thyroid. Talk to a pharmacist or doctor before using it, especially if you have a thyroid condition.
