Drug & supplement interaction

California Poppy + Protriptyline

Protriptyline brand name: Vivactil.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between California Poppy and Protriptyline 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

California Poppy and Protriptyline

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 Protriptyline and California Poppy 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 Protriptyline

Interactions in our licensed database are recorded against drug classes, not just single drug names. Protriptyline is filed under 7 classifications — including tricyclic antidepressants (tcas), antidepressant drugs, serotonergic drugs. California Poppy has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Protriptyline’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.

No Interaction Found — But Data Suggests California Poppy and Protriptyline 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.

The most serious there right now: Activated Charcoal (major), Henbane (major), Lithium (major), Scopolia (major) and 5-htp (moderate).

From our pharmacist’s overview on the Protriptyline page

“Protriptyline (Vivactil) is an older tricyclic antidepressant, and I read its supplement list with genuine care because so much of it piles onto what the drug already does. Four of the 93 ingredients on file rate major, and those deserve your attention before anything else.”

About California Poppy

What is California Poppy?

California Poppy
  • Anxiety and stress
  • Trouble sleeping (insomnia)
  • Mild aches and pains
  • Restlessness or nervous tension
  • Bedwetting in children (traditional use)

California poppy is a traditional herbal remedy used mainly for anxiety and sleep problems, often combined with other calming herbs. Human research is very limited, so its true benefits are not well proven. It is generally considered mild, but should be avoided during pregnancy and breastfeeding and used with caution by anyone taking sedating medicines.

Eschscholzia californica · Papaveraceae · Above-ground parts (flowers, leaves, stems) and roots · Tea, tincture, liquid extract, capsules, dried herb

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

California Poppy: dosing

There is no official, standardized dose for California poppy. Products vary widely in strength, and it is often part of herbal blends. The best approach is to follow the directions on the product label and not exceed the recommended amount.It is commonly taken in the evening when used for sleep, but timing and amount should be guided by the product and your own response.

About Protriptyline

What Is Protriptyline Used For?

Brand name: Vivactil

Protriptyline Hydrochloride tablets are used to treat symptoms of mental depression in patients who are under close medical supervision. Because it has activating (energizing) properties rather than sedating ones, it may be especially useful for people with depression who feel withdrawn or have very low energy.

Do California Poppy and Protriptyline have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other.

Protriptyline is filed under 7 classifications, and California Poppy has documented interactions with 1 drug class — none of Protriptyline'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.
