Scurvy Grass and Olanzapine

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 Olanzapine and Scurvy Grass 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 Scurvy Grass at all — not against Olanzapine, 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.

What Olanzapine’s Own FDA Label Lists

This is not an interaction — none of it involves Scurvy Grass. These are the most notable effects listed in the ADVERSE REACTIONS section of Olanzapine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 9 of them are worth acting on rather than waiting out — marked below.

  • Memory problems Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Confusion Worth acting on
  • Chest pain Worth acting on
  • Low mood Worth acting on
  • Raised blood pressure Worth acting on
  • Shortness of breath Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on

Showing the 10 most notable of 40 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Olanzapine. Read the label on DailyMed › Where a percentage is shown, it is the share of 109,181 voluntary FDA FAERS reports for Olanzapine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Scurvy Grass’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Scurvy Grass side to compare — that is a limit of the record, not a statement that Scurvy Grass has no side effects.

“Olanzapine (Zyprexa) is an antipsychotic prescribed for schizophrenia and bipolar disorder, and adding supplements to it warrants genuine care. Four of the 160 ingredients on file rate major, and those four deserve your attention before anything else: lithium supplements raise the risk of serotonin syndrome, activated charcoal can trap…”

About Scurvy Grass

What is Scurvy Grass?

  • Historical scurvy prevention (vitamin C source)
  • General tonic
  • Mouth and gum health
  • Digestive support
  • Mild antiseptic/wound rinse

Scurvy grass is a traditional European herb historically eaten by sailors as a source of vitamin C to prevent scurvy. Today it has little proven medical use beyond its vitamin C content, and modern research is very limited. If you simply need vitamin C, well-studied foods and supplements are more reliable.

Cochlearia officinalis · Brassicaceae · Leaves and aerial parts (fresh herb) · Fresh leaves, tea, tincture, juice, dried herb

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

Scurvy Grass: dosing

There is no established standardized dose for scurvy grass. Historically it was used as a fresh leafy green or its juice, in everyday food-like amounts, rather than measured medicinal doses.If you use a commercial product such as a tea or tincture, follow the directions on the label and do not exceed the suggested amount.

About Olanzapine

What Is Olanzapine Used For?

Brand name: Zyprexa

Olanzapine treats schizophrenia and the manic or mixed episodes of bipolar I disorder in both adults and adolescents (ages 13–17). It can also be used alongside valproate or lithium to treat manic or mixed episodes in adults. When combined with fluoxetine, olanzapine tablets and orally disintegrating tablets are used to treat depressive episodes associated with bipolar I disorder and treatment-resistant depression in adults.

Olanzapine intramuscular injection (short-acting) is used by healthcare providers to quickly calm acute agitation in adults with schizophrenia or bipolar I mania. Zyprexa Relprevv — a separate, long-acting intramuscular formulation available only through a restricted program — is indicated specifically for the treatment of schizophrenia in adults.
