HelloPharmacist Scorecard of Feverfew 380 mg by Puritan's Pride

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This supplement contains one active ingredient: feverfew, a plant extract dosed at 380 mg per capsule. The capsule itself is made from gelatin, an inactive ingredient that holds everything together.

Feverfew has been used traditionally for centuries, particularly for migraine and headache support. The herb contains compounds that some research suggests may affect how your body handles inflammation and blood clotting.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Feverfew product and its label doesn't state a use — see Feverfew's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold doesn't establish that feverfew works reliably for the conditions listed—tension headache, prurigo nodularis (a skin condition), psoriasis, and rheumatoid arthritis all carry a rating of insufficient reliable evidence. That doesn't mean it's ineffective; it means the studies so far haven't been strong enough to confirm it one way or the other.

If you're thinking about using it for migraine or headache, talk with your doctor about whether the current evidence fits your situation.

The evidence, ingredient by ingredient Feverfew

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Feverfew is generally well tolerated over the short term in capsule form, though some people do get mouth irritation, allergic reactions, or gastrointestinal side effects—nausea, heartburn, diarrhea, constipation, bloating, and abdominal pain are the most common. Skin rash can occur in sensitive individuals.

Chewing fresh feverfew leaves is much more likely to cause mouth sores and tongue irritation than taking a capsule. If you've been taking feverfew regularly and stop suddenly, you may experience rebound symptoms—anxiety, headaches, and insomnia—sometimes called post-feverfew syndrome.

During pregnancy, feverfew is not advised; it may stimulate the uterus and its safety isn't established. There isn't enough reliable safety data to recommend it while breastfeeding either.

Talk with your doctor or pharmacist before taking it if you're pregnant or nursing.

Side effects, ingredient by ingredient Feverfew

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Feverfew.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 930 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking feverfew, double-check with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs like warfarin, aspirin, or clopidogrel—feverfew may increase bleeding risk. Additionally, it may raise levels of any medication your liver processes through CYP2C19, CYP2D6, CYP1A2, CYP2C9, CYP3A4, or CYP2C8 pathways, which includes a wide range of common medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Feverfew may be worth considering if you're exploring options for migraine or headache, but the evidence of how well it actually works isn't solid yet. The biggest concern is its potential to interact with blood thinners and many other medications through how your liver breaks them down—so check your medications first with your doctor or pharmacist.

It's generally well tolerated, but watch for nausea, heartburn, or mouth irritation, and avoid it if you're pregnant or breastfeeding.

Anticoagulant/Antiplatelet Drugs

Theoretically, feverfew might have additive effects and increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Laboratory research suggests that feverfew may inhibit platelet aggregation. Additionally, in one case report, a 36-year-old patient taking feverfew 2400 mg daily for 3 months experienced vaginal bleeding and a prolonged menstrual cycle, with a modest increase in partial thromboplastin time (PTT) and prothrombin time (PT).

Feverfew 380 mg by Puritan's Pride: Common Questions

Does Feverfew 380 mg by Puritan's Pride interact with any medications?
Yes. Based on its ingredients, Feverfew 380 mg has a known interaction with 929 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Feverfew 380 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What is feverfew supposed to do?
Feverfew has been used traditionally for migraine and headache, and some research suggests it may help with skin conditions like psoriasis and rheumatoid arthritis. However, the evidence we hold doesn't yet confirm it's reliably effective for any of these—more research is needed.
Can I take this while pregnant or breastfeeding?
No—feverfew is rated possibly unsafe in pregnancy because it may stimulate the uterus, and its safety isn't established. There also isn't enough data to recommend it while breastfeeding. Talk with your doctor before taking it if either applies to you.
What are the most common side effects?
Gastrointestinal symptoms are most frequent: nausea, heartburn, diarrhea, constipation, bloating, and abdominal pain. Some people also get skin rash. Chewing fresh feverfew leaves is much more likely to cause mouth sores and tongue irritation than taking this capsule form.
What happens if I stop taking feverfew after a long time?
Stopping suddenly after regular use may cause rebound symptoms—anxiety, headaches, and insomnia. This is sometimes called post-feverfew syndrome. If you've been taking it regularly and want to stop, talk with your doctor or pharmacist about how to do it safely.
Does this interact with blood thinners?
Yes—feverfew may increase bleeding risk if used alongside blood thinners like warfarin or antiplatelet drugs like aspirin. Lab work suggests it can inhibit platelet function, and one patient on high-dose feverfew did report unusual bleeding. Check with your doctor or pharmacist before combining them.
Why does this interact with so many medications?
Feverfew appears to slow how your liver processes drugs through several pathways (CYP2C19, CYP2D6, CYP1A2, CYP2C9, CYP3A4, and CYP2C8). Many common medications—from antidepressants to heart drugs to diabetes medications—are cleared this way, so feverfew could theoretically raise their levels. Lab evidence supports this; it hasn't been confirmed in patients yet, but it's important to check.
