Interaction report

Securinega Suffruticosa and Isosorbide Mononitrate

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 Isosorbide Mononitrate and Securinega Suffruticosa 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 Isosorbide Mononitrate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Isosorbide Mononitrate is filed under 3 classifications — nitrates, vasodilators, oral drugs. Securinega Suffruticosa has documented interactions with 1 drug class — the most serious being stimulant drugs (moderate) — and none of Isosorbide Mononitrate’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.

Read the label on DailyMed › Where a percentage is shown, it is the share of 20,621 voluntary FDA FAERS reports for Isosorbide Mononitrate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it.

About Securinega Suffruticosa

What is Securinega Suffruticosa?

  • Nerve and muscle weakness
  • Fatigue and low energy
  • Nerve-related conditions in traditional medicine
  • Childhood paralysis (historical traditional use)
  • General tonic

Securinega suffruticosa is a shrub used in traditional East Asian medicine, best known for an alkaloid called securinine that strongly stimulates the nervous system. Because securinine is powerful and can cause seizures and serious toxicity, this plant is not a safe or well-studied dietary supplement, and it should not be used for self-treatment. Talk to a doctor or pharmacist before considering anything containing this plant.

Securinega suffruticosa · Phyllanthaceae · Leaves, twigs, and aerial parts (roots in some traditional preparations) · Dried herb decoction, tinctures, and isolated alkaloid extracts (mainly used in research settings)

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

Securinega Suffruticosa: dosing

There is no established, standardized safe dose of Securinega suffruticosa for use as a supplement. The plant's alkaloid content can vary, and the active compound securinine has a narrow margin between any effect and toxic effects.Because of these safety concerns, we cannot recommend a specific amount.

About Isosorbide

What Is Isosorbide Used For?

Brand names: Imdur, Angeze, Dynamin, Elantan, Ismo, Chemydur 60XL, Elantan LA, Isib 60XL, Ismo Retard, Isodur, Isotard, Modisal LA, Modisal XL, Monomax SR, Monomax XL, Angeze SR, Monomil XL, Monosorb XL, Zemon

Isosorbide is used to prevent angina pectoris — chest pain or tightness caused by coronary artery disease. Both isosorbide dinitrate tablets and isosorbide mononitrate tablets (including Monoket and Isordil) are used for this purpose.

Important: none of these oral formulations work fast enough to stop a chest pain episode that has already started. They are taken on a schedule to prevent angina, not to treat it in the moment.

Most-Reported Side Effects for Isosorbide Mononitrate

From FAERS, the FDA’s public side-effect reporting system (20,621 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
