Veronica + Dihydroergotamine
Dihydroergotamine brand names: Migranal, DHE-45.
We found no known interaction between Veronica and Dihydroergotamine 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.
Veronica and Dihydroergotamine
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 Dihydroergotamine and Veronica 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 Veronica at all — not against Dihydroergotamine, 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.

From our pharmacist’s overview on the Dihydroergotamine page
“Dihydroergotamine (Migranal, DHE-45) stops migraines by tightening blood vessels, and this interaction list deserves genuine care. Four of its 156 supplement interactions rate major, and the largest theme, covering 121 ingredients, involves the CYP3A4 enzyme that clears the drug.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Veronica 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 Veronica reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Veronica and Dihydroergotamine records this page draws on were last updated June 22, 2026.
- 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 Veronica
What is Veronica?
- Coughs and respiratory complaints
- Digestive upset and appetite stimulation
- Gout, arthritis, and rheumatic complaints
- Kidney and urinary tract conditions
- Mouth and throat inflammation (topical)
Veronica (speedwell) is a traditional European herb used mainly for coughs, digestive complaints, and joint problems, but there is very little modern scientific evidence to show it actually works for any of these. It is generally considered mild, but its safety has not been well studied, so check with a pharmacist or doctor before using it — and avoid it during pregnancy and breastfeeding.
Veronica officinalis · Plantaginaceae · Above-ground (aerial) parts — the flowering herb, including leaves and stems · Tea (infusion), tincture, dried herb, and topical rinses or gargles
An interaction check asks whether these two react with each other — it does not ask whether Veronica is a good idea for someone in your situation. Here is what our Veronica record says about it on its own.
Veronica: dosing
There is no standardized or scientifically established dose for Veronica. Traditional use has mostly involved a tea made from the dried herb or a tincture, but exact safe and effective amounts have not been determined by research.If you use a commercial product, follow the directions on the label and do not exceed the recommended amount.

About Dihydroergotamine Injection
What Is Dihydroergotamine Injection Used For?
Brand names: Migranal, DHE-45
Dihydroergotamine injection is used to stop a migraine headache once it has started — with or without the visual or sensory warning signs known as aura. It is also used to treat cluster headaches in adults.
It is not used to prevent migraines from happening, and it is not for hemiplegic migraine (migraine that causes temporary paralysis) or migraine with brainstem aura. Brekiya is specifically approved for subcutaneous (under-the-skin) self-injection using an autoinjector device.
Most-Reported Side Effects for Dihydroergotamine
From FAERS, the FDA’s public side-effect reporting system (1,268 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
