Medically reviewed by · Updated June 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Vitamin O and Ziprasidone in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Ziprasidone states a food rule worth keeping to.

Vitamin O and Ziprasidone

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 Ziprasidone and Vitamin O 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 Vitamin O at all — not against Ziprasidone, 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 Ziprasidone’s Own FDA Label Lists

This is not an interaction — none of it involves Vitamin O. These are the most notable effects listed in the ADVERSE REACTIONS section of Ziprasidone’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Mania or an unusually elevated mood Worth acting on
  • Serotonin syndrome Worth acting on
  • Trouble swallowing Worth acting on
  • Hallucinations Worth acting on
  • An irregular heartbeat Worth acting on
  • Seizures Worth acting on
  • Chest pain Worth acting on
  • Shortness of breath Worth acting on
  • A low white blood cell count Worth acting on
  • A higher chance of infection Worth acting on

Showing the 10 most notable of 29 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 Ziprasidone. Read the label on DailyMed › Where a percentage is shown, it is the share of 19,927 voluntary FDA FAERS reports for Ziprasidone that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Vitamin O’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Vitamin O side to compare — that is a limit of the record, not a statement that Vitamin O has no side effects.

How to take them

Some Ziprasidone Products Have a Food Rule — Vitamin O Should Not Break It

At least one FDA label for a product containing Ziprasidone says to take it with food. If you take Vitamin O on an empty stomach out of habit, keep them separate — and take Ziprasidone with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ziprasidone products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

( 2.4 ) 2.1 Administration Information for GEODON Capsules Administer GEODON capsules orally with food.

From the Dosage and Administration section of the FDA label we read for Ziprasidone — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Ziprasidone page

“Ziprasidone (Geodon) is an antipsychotic that already carries a warning about disturbing the heart's electrical rhythm, so a list with 11 major-rated interactions calls for real care before mixing in supplements. Most of the 188 ingredients on file touch the liver enzyme, CYP3A4, that clears ziprasidone from the body.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Vitamin O is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Vitamin O reference on this page ↓

  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Vitamin O

What is Vitamin O?

  • Claimed to add 'stabilized oxygen' to the body
  • General energy and wellness
  • Marketed for improved breathing or vitality

"Vitamin O" is not a real vitamin. It is a marketing name used for liquid products typically containing saltwater (a saline solution) sold with claims of providing 'stabilized oxygen' to the body. There is no credible scientific evidence that these products work, and U.S. regulators have taken action against false advertising for them, so they are best avoided.

Not applicable (manufactured liquid product) · Liquid drops

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

Vitamin O: dosing

There is no established or recommended dose for Vitamin O because it is not a recognized nutrient and has no proven benefit. Different brands give different directions, usually a set number of drops in water.Since the product is unproven, the most cautious advice is to avoid it.
