The bottom line No known interaction

We found no known interaction between Vitex Agnus-castus and Amphetamine 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.

Vitex Agnus-castus and Amphetamine

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 Amphetamine and Vitex Agnus-castus 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 Amphetamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amphetamine is filed under 6 classifications — including monoamine oxidase inhibitors (maois), amphetamines, stimulant drugs. Vitex Agnus-castus has documented interactions with 5 drug classes — the most serious being antipsychotic drugs (moderate), contraceptive drugs (moderate) and dopamine agonists (moderate) — and none of Amphetamine’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.

From our pharmacist’s overview on the Amphetamine page

“Amphetamine (Dyanavel XR, Adzenys ER, Mydayis) is a prescription stimulant, usually taken for ADHD, and its interaction list is one to approach with genuine care.

About Vitex Agnus-castus

What is Vitex Agnus-castus?

Vitex Agnus-castus
  • Premenstrual syndrome (PMS)
  • Irregular or absent menstrual periods
  • Cyclical breast pain (mastalgia)
  • Menopause symptoms
  • Fertility support

Vitex (chasteberry) is an herbal remedy most often used for PMS and menstrual cycle problems, and the strongest evidence is for easing some PMS symptoms. It is generally well tolerated by many adults, but it can affect hormone-related processes, so anyone who is pregnant, breastfeeding, or has a hormone-sensitive condition should talk with a healthcare professional first.

Vitex agnus-castus · Lamiaceae · Dried ripe fruit (berries) · Capsules, tablets, liquid extracts (tinctures), and teas

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

Vitex Agnus-castus: dosing

There is no single official or proven dose for vitex. Products differ widely in how they are made and how concentrated they are, so the amount per dose varies from one brand to another. Standardized extracts are common, but a universal best dose has not been established.The safest approach is to follow the directions on the product label and not take more than recommended. Because vitex may take several weeks or even a few menstrual cycles before any effect is noticed, it is often used over time.
