Drug & supplement interaction

Deanol + Valbenazine Tosylate

Valbenazine Tosylate brand name: Ingrezza.

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

We found no known interaction between Deanol and Valbenazine Tosylate 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 two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Deanol and Valbenazine Tosylate

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 Valbenazine Tosylate and Deanol 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.

How we checked

Why No Interaction Is Listed for Valbenazine Tosylate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Valbenazine Tosylate is filed under 5 classifications — including qt interval-prolonging drugs, cytochrome p450 2d6 (cyp2d6) substrates, cns depressants. Deanol has documented interactions with 2 drug classes — the most serious being anticholinergic drugs (minor) and cholinergic drugs (minor) — and none of Valbenazine Tosylate’s classifications are among them.

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 to actually watch for

No Interaction Found — But Data Suggests Deanol and Valbenazine Tosylate May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. 2 of them are worth acting on rather than waiting out — marked below.

Effects for Valbenazine Tosylate come from the ADVERSE REACTIONS section of its FDA label; effects for Deanol come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 24,614 voluntary FDA FAERS reports for Valbenazine Tosylate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Valbenazine Tosylate Is Prescribed For, and What Deanol Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Valbenazine Tosylate is a prescription medicine with approved uses on its FDA label. Deanol is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Valbenazine Tosylate is prescribed for: Valbenazine — sold as Ingrezza and INGREZZA Sprinkle — is approved for two conditions in adults. The first is tardive dyskinesia, a movement disorder that causes uncontrolled, repetitive facial or body movements, often brought on by long-term use of certain psychiatric medications. The second is chorea associated with Huntington's disease, which refers to the involuntary, dance-like jerking movements that are a hallmark of that condition. Both Ingrezza and INGREZZA Sprinkle are approved for both of these uses.

Deanol has been studied for:

  • Tardive dyskinesia studied, not established Deanol has been studied for this. Natural Medicines rates the evidence: Likely Ineffective Read what the research shows

    Deanol for tardive dyskinesia

    Oral deanol does not improve symptoms of tardive dyskinesia.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Valbenazine Tosylate on your own; if you are taking Deanol for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Valbenazine Tosylate

This page covers Deanol only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Valbenazine Tosylate page lists 216 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), American Hellebore (major), Arsenic (major) and Beer (major).

By severity: 14 major · 164 moderate · 38 minor.

From our pharmacist’s overview on the Valbenazine Tosylate page

“The list for valbenazine (Ingrezza), the medicine for tardive dyskinesia, warrants genuine care, since 14 of its 216 supplement and herbal interactions are rated major. Most of those majors either pile extra sedation onto a drug that can already make people drowsy, alcohol being the everyday example, or shift how much valbenazine reach…”

About Deanol

What is Deanol?

Deanol
  • Memory and focus
  • Mood and mental clarity
  • ADHD-type symptoms
  • Skin firmness (topical)
  • General brain health

Deanol (DMAE) is a compound related to choline that is marketed for memory, focus, and mood, but solid human evidence for most of these uses is limited or mixed. It can cause side effects in some people, and it should be avoided in pregnancy and breastfeeding because its safety is not established. Talk to your pharmacist or doctor before trying it.

Synthetic or naturally occurring compound (not a plant part) · Capsules, tablets, liquid drops, powder; also found in skin creams

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

Deanol: dosing

There is no official or standardized dose of deanol for supplement use. Products vary widely in strength and form, so the amount in one brand may differ from another.The safest approach is to follow the directions on the product label and not exceed them.

Taking Deanol and Valbenazine Tosylate Together: Common Questions

Is it safe to take Deanol with Valbenazine Tosylate?
We do not list a known interaction between Deanol and Valbenazine Tosylate. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Deanol and Valbenazine Tosylate have any of the same side effects?
Yes — our sources link each of them separately to 9 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Deanol and Valbenazine Tosylate used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Deanol in each. That is a conversation for your prescriber, especially if Valbenazine Tosylate is being adjusted to a target.
How was the Deanol and Valbenazine Tosylate combination checked?
Interactions in our licensed database are recorded against drug classes. Valbenazine Tosylate is filed under 5 classifications, and Deanol has documented interactions with 2 drug classes — none of Valbenazine Tosylate's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Deanol interact with any other medications?
Yes. Deanol has 219 documented drug interactions in our database — Valbenazine Tosylate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Valbenazine Tosylate interact with any supplements?
Yes. Valbenazine Tosylate has documented interactions with 216 supplements in our database — Deanol is not one of them. The Valbenazine Tosylate interaction page linked on this page lists every one, ranked by severity.
