Feng Shui and Isosorbide Dinitrate

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 Dinitrate and Feng Shui 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 Feng Shui at all — not against Isosorbide Dinitrate, 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.

What Isosorbide Dinitrate’s Own FDA Label Lists

This is not an interaction — none of it involves Feng Shui. These are the most notable effects listed in the ADVERSE REACTIONS section of Isosorbide Dinitrate’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • A heart attack Worth acting on mentioned in 6.2% of FDA reports for Isosorbide Dinitrate
  • Kidney stones Worth acting on
  • Muscle weakness Worth acting on
  • Bleeding in the gut Worth acting on
  • Low potassium Worth acting on
  • A slow heartbeat Worth acting on
  • Chest pain Worth acting on mentioned in 5.9% of FDA reports for Isosorbide Dinitrate
  • Heart failure Worth acting on
  • Shortness of breath Worth acting on mentioned in 8.6% of FDA reports for Isosorbide Dinitrate
  • Fainting Worth acting on

Showing the 10 most notable of 56 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Isosorbide Dinitrate. Read the label on DailyMed › Where a percentage is shown, it is the share of 19,814 voluntary FDA FAERS reports for Isosorbide Dinitrate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Feng Shui’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Feng Shui side to compare — that is a limit of the record, not a statement that Feng Shui has no side effects.

From our pharmacist’s overview on the Isosorbide Dinitrate page

“Isosorbide dinitrate (Isordil, Isoket) relaxes blood vessels to prevent and relieve angina, so a supplement that pushes that relaxation further, or works against it, is not a small thing, and this list of 22 warrants genuine care. Four entries rate major: herbs with vasodilating effects of their own, like hawthorn, that can stack on to…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Feng Shui 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 Feng Shui reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Feng Shui and Isosorbide Dinitrate records this page draws on were last updated June 20, 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 Feng Shui

What is Feng Shui?

"Feng Shui" is not a dietary supplement or medicinal herb. It is a traditional Chinese practice of arranging living and working spaces to promote harmony and balance, so there is nothing to take or dose. If you saw "Feng Shui" listed as a supplement product, the name is being used as branding, and you should check the actual ingredients on the label and ask a pharmacist before using it.

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

Feng Shui: dosing

There is no dose for Feng Shui because it is not a supplement or herb.

About Isosorbide

What Is Isosorbide Used For?

Brand names: Isordil, Angitak, Cedocard Retard, Isoket Retard, Isoket

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 Dinitrate

From FAERS, the FDA’s public side-effect reporting system (19,814 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dyspnea 1,696 reports
Nausea 1,406 reports
Fatigue 1,382 reports
Dizziness 1,336 reports
Diarrhea 1,334 reports
