HelloPharmacist Scorecard of Curaphen Extra Strength by EuroMedica
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.
What’s inside
Low disclosure
Curaphen Extra Strength has four active ingredients. Nattokinase is an enzyme extracted from fermented soy that may help break down fibrin (a protein involved in blood clots).
The product also contains BOS-10, DL-Phenylalanine, and BCM-95 Curcugreen — we can't comment on their roles because we hold no detailed data on them. The tablet is rounded out with inactive ingredients like cellulose, stearic acid, silica, and magnesium stearate, which are common fillers and binders.
Does it work?
Insufficient evidence
Evidence for nattokinase in angina, atherosclerosis, cancer, cardiovascular disease, and chronic fatigue syndrome is insufficient — the research we have isn't strong enough to rate it one way or the other. We hold no effectiveness ratings for the other three active ingredients in this product.
How safe is it?
Well-documented data
Nattokinase is generally well tolerated short-term, but because it thins the blood, you should be cautious if you have any bleeding risk. Rare cases of bleeding — including serious brain bleeding — have been reported, especially when nattokinase is combined with other blood thinners.
Some people have also had allergic reactions to nattokinase, with symptoms like throat or airway swelling appearing within a couple of hours of taking it. The safety data advises against nattokinase during pregnancy and while breastfeeding because there isn't enough information to know it's safe.
Meds to double-check
Moderate interaction found
Before you take Curaphen Extra Strength, check with us if you're on blood thinners or antiplatelet drugs (like warfarin, apixaban, or aspirin) — Moderate risk of increased bleeding. Also double-check if you take blood pressure medications, since nattokinase may lower blood pressure further.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product is designed for people interested in fibrin breakdown and cardiovascular support, but nattokinase's blood-thinning effects mean you should talk to your pharmacist before starting it if you take any blood thinners, antiplatelet drugs, or blood pressure medicines. Pregnant or breastfeeding?
Skip nattokinase-containing products until you've talked with your doctor.

Curaphen Extra Strength by EuroMedica Drug Interactions
HelloPharmacist Interaction Report
Curaphen Extra Strength by EuroMedica contains nattokinase, which has documented interactions with two major drug categories.
The most serious concern is with blood thinners and antiplatelet drugs (like aspirin and warfarin) — nattokinase can thin the blood further and raise the risk of bleeding. There's even a case report of brain bleeding in someone who combined nattokinase with low-dose aspirin.
Nattokinase may also lower blood pressure, so it could cause dizziness or weakness if you're already taking blood pressure medications (a Moderate concern).
Read the full breakdown — every affected drug type, severity by severity
We couldn't check three other active ingredients in this product: BOS-10, DL-Phenylalanine, and BCM-95 Curcugreen. We hold no interaction data for them, so we can't say whether they interact with any medications.
Altogether, these interactions span 287 individual medications. If you take any blood thinners, antiplatelet drugs, or blood pressure medicines, run your exact medications through the checker below before you start this product.

BOS-10
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, Boswellia serrata might increase the levels of CYP1A2 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP1A2 enzymes.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, Boswellia serrata might increase the levels of CYP2C19 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2C19 enzymes.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, Boswellia serrata might increase the levels of CYP2C9 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2C9 enzymes.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, Boswellia serrata might increase the levels of CYP2D6 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2D6 enzymes.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, Boswellia serrata might increase or decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP3A4 enzymes. Other in vitro research shows that Boswellia serrata extract inhibits CYP3A4 enzymes at most concentrations, although it may modestly induce enzyme activity at low concentrations.
Immunosuppressants
Theoretically, Boswellia serrata might alter the effects of immunosuppressive drugs.
Some in vitro research suggests that Boswellia serrata extracts might inhibit mediators of autoimmune disorders such as leukotrienes and reduce production of antibodies and cell-mediated immunity. However, other in vitro research suggests that, when coupled with calcium ions, boswellic acids containing the keto group have immunostimulant properties within specific cell signaling pathways.
Nattokinase
Anticoagulant/Antiplatelet Drugs
Nattokinase might increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
Nattokinase has thrombolytic and anticoagulant effects. There is a case report of intracranial hemorrhage in a patient who added nattokinase to aspirin therapy.
Antihypertensive Drugs
Theoretically, nattokinase might increase the risk of hypotension when used with antihypertensive drugs.
Some clinical research suggests that nattokinase may reduce systolic and diastolic blood pressure.
