Gamma-oryzanol and Lanadelumab (Shp643)

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Lanadelumab (Shp643) and Gamma-oryzanol in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Gamma-oryzanol at all — not against Lanadelumab (Shp643), and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

About Gamma-oryzanol

What is Gamma-oryzanol?

  • High cholesterol
  • Menopausal symptoms
  • Athletic performance and muscle building
  • Mild anxiety
  • Skin protection (topical)

Gamma-oryzanol is a mix of plant compounds taken from rice bran oil, used mainly for cholesterol, menopause symptoms, and as a sports supplement. The evidence is limited and mostly comes from small or older studies, so benefits are not well proven. It appears generally well tolerated, but talk with your pharmacist or doctor before using it.

Poaceae · Rice bran oil (derived from Oryza sativa bran) · Capsules, tablets, powder, topical creams

An interaction check asks whether these two react with each other — it does not ask whether Gamma-oryzanol is a good idea for someone in your situation. Here is what our Gamma-oryzanol record says about it on its own.

Gamma-oryzanol: dosing

There is no official or standardized dose for gamma-oryzanol. Doses used in research have varied widely, and what works for one use may not apply to another.The best approach is to follow the directions on the product label and not take more than recommended.
