Garden Cress and Nusinersen Sodium

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Nusinersen Sodium

Nusinersen Sodium falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Garden Cress interacts with.

Theoretically, garden cress seed may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Animal research suggests that garden cress seed extract can increase bleeding time when used in combination with the antiplatelet agent clopidogrel. This has not been shown in humans and it is unclear if garden cress seed itself has anticoagulant or antiplatelet effects.
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

Here's the honest picture for Spinraza (nusinersen). The interaction on file is about garden cress seed possibly adding to bleeding risk when paired with blood thinners. That concern comes from animal research, where cress seed extract lengthened bleeding time alongside clopidogrel. It has not been shown in people, and we're not even sure garden cress itself thins the blood.

With Spinraza, the practical worry is its delivery: it's injected into the fluid around your spine (a lumbar puncture), so anything that nudges bleeding could matter around that procedure. Food amounts of cress are unlikely to be an issue. If you take concentrated cress seed supplements, just mention it to your care team before each dose so they can weigh in.

From our pharmacist’s overview on the Nusinersen Sodium page

“Spinraza (nusinersen) is given by spinal injection to treat spinal muscular atrophy, and it carries its own warnings for low platelets and kidney stress, which makes the 208 supplements on this page worth real vigilance rather than a shrug. All but six of them, 202 ingredients, could raise bleeding risk by thinning the blood or dulling…”

About Garden Cress

What is Garden Cress?

Garden Cress
  • Digestive support
  • Bone health
  • Iron and vitamin source
  • Cough and respiratory comfort
  • Boosting breast milk (traditional)
  • Constipation relief

Garden cress is a nutritious leafy herb and seed used widely in cooking and traditional medicine, providing vitamins, minerals, and fiber. While it has a long history of use for digestion, bone health, and lactation, strong human research supporting most medicinal claims is limited. It is generally safe as a food, but concentrated seed supplements should be used cautiously and avoided in pregnancy.

About Nusinersen Injection

What Is Nusinersen Injection Used For?

Brand name: Spinraza

Spinraza (nusinersen) is used to treat spinal muscular atrophy (SMA) — a genetic disease that causes progressive muscle weakness by reducing the body's ability to make a protein called SMN (survival motor neuron). Spinraza is approved for pediatric and adult patients with SMA.

Spinraza is given by intrathecal injection — directly into the fluid surrounding the spinal cord — so the medicine can reach the central nervous system where it's needed most.
