Stereospermum 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 Stereospermum 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.

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.

Stereospermum safety at a glance

Stereospermum overall Not established Human safety data are very limited, so its overall safety is not well established.
Pregnancy Avoid Not enough safety information exists, so it is best avoided during pregnancy.
Breastfeeding Avoid There is no reliable safety data for breastfeeding, so avoid use.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Olanzapine

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Olanzapine’s Own FDA Label Lists

This is not an interaction — none of it involves Stereospermum. 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
  • Weight gain mentioned in 6.3% of FDA reports for Olanzapine

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. Stereospermum’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Stereospermum side to compare — that is a limit of the record, not a statement that Stereospermum has no side effects.

About Stereospermum

What is Stereospermum?

  • Fever
  • Inflammation and pain
  • Digestive complaints
  • Respiratory issues
  • General tonic in Ayurveda

Stereospermum is a tree used in traditional Ayurvedic medicine, most notably as one of the herbs in the classic 'Dashamula' (ten-root) formula. There is very little high-quality human research to confirm its benefits, so its uses remain largely traditional. If you are considering it, talk with a pharmacist or doctor first, especially if you are pregnant, breastfeeding, or taking other medicines.

Stereospermum suaveolens · Bignoniaceae · Root bark, stem bark, leaves, and flowers · Powder (churna), decoction, capsules, and as part of traditional Ayurvedic herbal blends

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

Stereospermum: dosing

There is no well-established standardized dose for Stereospermum. Traditional preparations vary, and it is often used as part of multi-herb formulas rather than alone.If you choose to use a product that contains it, follow the directions on the product label and do not exceed the recommended 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.
