Additionally, although there is no interaction, the label for Nisoldipine states a food rule worth keeping to.

Datura Wrightii and Nisoldipine

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 Nisoldipine and Datura Wrightii 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 Nisoldipine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nisoldipine is filed under 4 classifications — including calcium channel blockers, antihypertensive drugs, cytochrome p450 3a4 (cyp3a4) substrates. Datura Wrightii has documented interactions with 2 drug classes — the most serious being anesthesia (moderate) and anticholinergic drugs (moderate) — and none of Nisoldipine’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 Datura Wrightii Itself Has Been Linked To

Everything above comes from the Natural Medicines adverse-effect record for Datura Wrightii — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Nisoldipine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Nisoldipine column appears here.

How to take them

Some Nisoldipine Products Have a Food Rule — Datura Wrightii Should Not Break It

At least one FDA label for a product containing Nisoldipine says to take it on an empty stomach. Most supplements — Datura Wrightii included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Nisoldipine on its own and move Datura Wrightii to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Nisoldipine products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

SULAR should be taken on an empty stomach (1 hour before or 2 hours after a meal).

From the Dosage and Administration section of the FDA label we read for Nisoldipine — where that label names a specific product, the instruction is that product's. See the Nisoldipine drug page ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Nisoldipine page

“Nisoldipine (Sular) lowers blood pressure by relaxing blood vessels, and the liver enzyme CYP3A4 controls how fast the body clears it, which is why this list warrants real vigilance. Grapefruit can drive nisoldipine levels up, while St.”

About Datura Wrightii

What is Datura Wrightii?

  • Traditional ritual and ceremonial use
  • Pain relief (traditional/topical)
  • Asthma and breathing complaints (historical)
  • Hallucinogenic/psychoactive effects
  • Skin and wound applications (folk use)

Datura wrightii (sacred datura or jimsonweed relative) is a highly poisonous desert plant that has been used in some traditional and ceremonial settings. It is not a safe dietary supplement — even small amounts can cause severe poisoning, hallucinations, and death. We strongly advise against using it.

Datura wrightii · Solanaceae · Leaves, flowers, seeds, and roots (all parts are toxic) · Traditional ceremonial preparations, topical pastes, smoked plant material (not a standard commercial supplement)

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

Datura Wrightii: dosing

There is no safe or established dose of Datura wrightii. Because the amount of toxic alkaloids varies enormously between plants and plant parts, there is no way to measure a safe amount at home.We do not provide dosing for this plant because we cannot recommend its use.

Taking Datura Wrightii and Nisoldipine Together: Common Questions

Is it safe to take Datura Wrightii with Nisoldipine?
We do not list a known interaction between Datura Wrightii and Nisoldipine. 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.
Should I take Datura Wrightii and Nisoldipine at the same time of day?

Interactions in our licensed database are recorded against drug classes. Nisoldipine is filed under 4 classifications, and Datura Wrightii has documented interactions with 2 drug classes — none of Nisoldipine'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.
