The bottom line No known interaction

We found no known interaction between Deanol and Amoxicillin 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.

Deanol and Amoxicillin

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 Amoxicillin 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.

Deanol safety at a glance

Deanol overall Use caution May be tolerated by some adults but evidence is limited and side effects can occur.
Pregnancy Avoid Not enough safety data; some animal research raises concern, so avoid use.
Breastfeeding Avoid Safety is unknown, so it is best to avoid while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Amoxicillin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amoxicillin is filed under 7 classifications — including penicillin, antibiotic drugs, nephrotoxic drugs. Deanol has documented interactions with 2 drug classes — the most serious being anticholinergic drugs (minor) and cholinergic drugs (minor) — and none of Amoxicillin’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.

Keep it in perspective

What to actually watch for

What Deanol Itself Has Been Linked To

This is not an interaction — nothing below involves Amoxicillin. It is the side-effect record for Deanol on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Deanol, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Mania or an unusually elevated mood / Low mood Worth acting on Additional detail

    “Orally, taking deanol at doses greater than 1000 mg daily has been reported to cause mood changes, including depression and hypomania, in patients with psychiatric conditions. Deanol 1500 mg daily has been reported to increase schizophrenic symptoms in patients with chronic schizophrenia.”

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.

About Amoxicillin

What Is Amoxicillin Used For?

Brand names: Amoxil Capsules, Trimox, Wymox, Amix, Amoram, Amoxident, Galenamox, Rimoxallin, Amoxil Injection

Amoxicillin treats bacterial infections in both adults and children, including ear, nose, and throat infections; lower respiratory tract infections; skin and skin structure infections; and genitourinary tract infections.

In adults only, amoxicillin is also used — always combined with other medications — to eradicate Helicobacter pylori (H. pylori), the bacteria behind duodenal ulcers. Getting rid of H. pylori has been shown to reduce the chance of those ulcers coming back. It is only effective against bacteria that are susceptible to it and will not work against viral infections like the common cold or flu.

Most-Reported Side Effects for Amoxicillin
