Methoxylated Flavones and Anagrelide

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

Why Are There 2 Interactions?

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

Moderate

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

1 of 2

Why this applies to Anagrelide

Anagrelide falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Methoxylated Flavones interacts with.

Some in vitro evidence suggests that methoxylated flavones might induce CYP1A2, possibly by increasing gene transcription. However, other in vitro research has not shown this effect. So far this interaction has not been reported in humans. Theoretically, concurrent use of methoxylated flavones and drugs metabolized by CYP1A2 might increase drug metabolism, decrease serum levels, and reduce effectiveness.
Some drugs metabolized by CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), Pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline (Slo-bid, Theo-Dur, others), zileuton (Zyflo), Zolmitriptan (Zomig), and others.
Severity Moderate 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 short version: your body relies on a liver enzyme called CYP1A2 to break down anagrelide. Lab studies hint that methoxylated flavones (the citrus-peel compounds) might speed up that enzyme. If that happened, your body could clear anagrelide a little faster, which in theory could lower its blood levels and make it work less well at keeping your platelet count down.

I want to be honest about the strength here: this is theoretical. It comes from test-tube research, the results conflict, and it has never actually been reported in people. Small amounts of citrus in food are very unlikely to matter, but concentrated supplements are a different story. Since anagrelide is closely dosed to your platelet numbers, just run any supplement past your pharmacist or doctor first.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Anagrelide also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

In vitro evidence suggests that some methoxylated flavones have antiplatelet effects. Theoretically, methoxylated flavones might additive effects when used with anticoagulant or antiplatelet drugs.
Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for anagrelide. This medicine already lowers your platelet count and gently slows how platelets clump together, so it has a mild blood-thinning side to it. In test-tube studies, citrus peel compounds called methoxylated flavones also showed a weak ability to keep platelets from sticking. Put the two together and, in theory, you could nudge the bleeding risk a little higher.

I want to be straight with you: this concern is theoretical, based on lab work rather than real patient cases, so it's not something to panic over. The flavone amounts you'd get from food are very unlikely to matter. Concentrated supplements are a bigger question mark. Just watch for easy bruising, nosebleeds, or bleeding gums, and check with your pharmacist or doctor before adding a supplement.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction 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.

From our pharmacist’s overview on the Anagrelide page

“Anagrelide (Agrylin) lowers platelet counts in people whose bone marrow makes too many, so bleeding risk is already the thing being managed, and most of this list pushes on exactly that. The bulk of these ingredients have some blood-thinning or antiplatelet activity of their own, from danshen and piracetam at the serious end down to fa…”

About Methoxylated Flavones

What is Methoxylated Flavones?

  • Antioxidant support
  • Circulation and blood vessel health
  • Anti-inflammatory support
  • Skin and aging support
  • General 'metabolism' or wellness blends

Methoxylated flavones (often called polymethoxyflavones) are a group of plant compounds, found mainly in citrus peel, that include substances like nobiletin and tangeretin. Lab and animal studies suggest possible antioxidant and anti-inflammatory effects, but solid human research is very limited, so their real-world benefits are unproven. Talk with a pharmacist or doctor before using them, especially if you take medicines or are pregnant or breastfeeding.

About Anagrelide

What Is Anagrelide Used For?

Brand name: Agrylin

Both Agrylin and generic anagrelide capsules are used to treat thrombocythemia secondary to myeloproliferative neoplasms — a condition where bone marrow disorders cause dangerously high platelet counts. The goal is to bring platelet counts down, lower the risk of dangerous blood clots (thrombosis), and ease related symptoms including bleeding and clotting events.
