Hesperidin and Dalteparin

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Dalteparin

Dalteparin falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Hesperidin interacts with.

Theoretically, hesperidin may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Animal research suggests that hesperetin, a bioflavonoid aglycone derivative of hesperidin, may have antiplatelet activity.
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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Dalteparin (Fragmin) is an injectable blood thinner that lowers your blood's ability to clot. Hesperidin, a citrus flavonoid, is thought to have a mild blood-thinning effect of its own. So the concern here is simple addition: putting the two together could nudge your clotting ability down a little more than the dalteparin alone, which theoretically raises the chance of bleeding or bruising.

I want to be honest about how soft this evidence is. It comes mainly from animal lab studies on a hesperidin breakdown product, not real-world reports in people, so the actual risk is likely small. Still, keep an eye out for things like easy bruising, nosebleeds, bleeding gums, or unusual bleeding. Before adding a hesperidin supplement, run it past your doctor or pharmacist so they can weigh in.

From our pharmacist’s overview on the Dalteparin page

“Dalteparin (Fragmin) is an injectable blood thinner used to prevent and treat dangerous clots, which is exactly why this list warrants real vigilance, and nearly all 218 ingredients on it thin the blood too. They are herbs and extracts with clot-inhibiting or antiplatelet effects of their own, so stacking them on dalteparin can push bl…”

About Hesperidin

What is Hesperidin?

Hesperidin
  • Hemorrhoids
  • Varicose veins and poor circulation
  • Leg swelling (venous insufficiency)
  • High blood pressure
  • Antioxidant support

Hesperidin is a flavonoid found in citrus fruits that is often combined with diosmin and used for vein and circulation problems like hemorrhoids and varicose veins. Some evidence supports these uses, but data for many other claims is limited. It is generally well tolerated, but pregnant and breastfeeding people should avoid it because safety has not been established.

About Dalteparin Injection

What Is Dalteparin Injection Used For?

Brand name: Fragmin

Fragmin is used to prevent clot-related problems in several situations. These include unstable angina and non-Q-wave heart attack (taken with aspirin), and deep vein thrombosis (DVT) after hip or abdominal surgery or during an acute illness that severely limits movement.

It is also used to treat symptomatic venous thromboembolism (VTE, a clot in a vein) and lower the chance it comes back. This applies to adults with cancer and to children from birth (gestational age at least 35 weeks). Fragmin is not indicated for the acute treatment of VTE.
