4-androsterone + Isosorbide Mononitrate
Isosorbide Mononitrate brand names: Imdur, Angeze, Dynamin, Elantan, Ismo, and others.
We found no known interaction between 4-androsterone and Isosorbide Mononitrate 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.
4-androsterone 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 4-androsterone 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.
4-androsterone safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
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. 4-androsterone has documented interactions with 1 drug class — the most serious being testosterone (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.
4-androsterone Does Interact With Other Medications
4-androsterone has 8 moderate known drug interactions in our database — Isosorbide Mononitrate isn’t one of them. If you take anything else, check it against the full list below.

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. 4-androsterone 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 4-androsterone reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The 4-androsterone and Isosorbide Mononitrate records this page draws on were last updated July 10, 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 4-androsterone
What is 4-androsterone?
- Muscle building
- Strength and athletic performance
- Boosting testosterone
- Bodybuilding cycles
4-Androsterone (sometimes called 4-DHEA) is a lab-made prohormone marketed to bodybuilders as a way to raise testosterone and build muscle, but human studies are very limited and it carries real risks like liver strain, hormone imbalance, and cholesterol changes. Its legal status is uncertain in many places, and it may cause a positive result on drug tests. We do not recommend it without close medical supervision, and it should be avoided in pregnancy and breastfeeding.
Synthetic steroidal compound (not a plant part) · Capsules, tablets, transdermal gels or creams, liquid drops
An interaction check asks whether these two react with each other — it does not ask whether 4-androsterone is a good idea for someone in your situation. Here is what our 4-androsterone record says about it on its own.
4-androsterone: dosing
There is no established, medically recommended dose for 4-androsterone. Doses used in bodybuilding come from product labels and informal community advice, not from rigorous clinical research.Because purity and strength can vary between products and the risks are significant, we cannot recommend a specific amount. Never assume that a higher dose is safer or more effective.

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.
