Reading size

How this medicine works

Organic nitrates relax vascular smooth muscle, especially veins, reducing venous return and myocardial oxygen demand. This helps explain angina prevention as well as headache, dizziness and hypotension; the mechanism is not an individual tablet-count or switching formula.

Check the market, names, dosage form and route together

A medicine may use different brand names across markets. Keep the market, brand, generic name, dosage form and route together; one matching field does not prove that two packs are the same or interchangeable.

FOR EVERYDAY QUESTIONS

After the leaflet, continue with the question you still need to check

What this pack is

ISORDIL is the brand name in this record; isosorbide dinitrate immediate-release tablets is the generic name. Read both together with the dosage form (oral tablet).

What this page can show

This is a source-traceable public record. It helps you read the product identity and its listed source documents; each market still needs its own current record check.

What to bring to the next conversation

Bring the actual pack, the label or prescription, and a complete medicine list when you speak with a pharmacist or clinician.

PRODUCT PRESENTATION IDENTITY

Strength, pack and device identity

Package strength is not an individual dose. These fields help identify the exact labelled product; they do not calculate how much, how often, a missed-use action, splitting, switching or conversion.

How to read a score line: ‘scored’ or ‘unscored’ first identifies this labelled presentation. A score line by itself does not permit self-splitting, reducing or changing the product. Only an explicit statement in the current label for this exact presentation, checked with a pharmacist against the prescription, can support any further handling.

5 source-backed strength, pack or device records — open the full list

First match the market, dosage form and labelled amount on the pack in hand. The number of tablets, sachets or devices in a pack is not a personal dose or schedule.

LABEL READING · NOT A PRESCRIPTION

ISORDIL enlarged label: an immediate-release oral preventive tablet is not acute chest-pain rescue

Reading level: drug-specific label reading. This record has been expanded around its dosage form or a higher-risk reading question; the current target-market label and professional review still apply.

ISORDIL TITRADOSE is an immediate-release oral isosorbide dinitrate tablet. The U.S. label states that onset is not rapid enough to abort an acute angina episode. The site does not generate an individual schedule or nitrate-free interval from the label.

  • Check route and release design first: this page covers immediate-release oral tablets, not sublingual or extended-release products. Do not convert, alternate or substitute by milligrams with IMDUR, MONOKET, NITROSTAT or historical ISORDIL sublingual/extended-release products.
  • PDE-5 inhibitors such as sildenafil, tadalafil or vardenafil, and the soluble guanylate cyclase stimulator riociguat, are contraindication-review scenarios with ISORDIL. Do not invent a few-hour separation to bypass them.
  • Dizziness, postural hypotension and syncope may occur. Co-listing antihypertensives, other vasodilators, diuretics or alcohol requires priority review. Unsteadiness on standing, a fall or fainting in an older person needs timely assessment.
  • The labelled 5 mg and 40 mg tablets are deeply scored, but the score is an appearance-identity field and does not permit self-splitting from a website. Check the exact product label and prescriber instructions.
  • Headache may accompany nitrate action, but it is not a basis for self-increasing, reducing, stopping, switching or changing timing. Sudden severe or unusual chest pain or headache, especially with neurological symptoms, needs immediate local medical support.

PHARMACOVIGILANCE · OFFICIAL ROUTES

Check safety information in the right market

Start with the public label or product record linked to this dossier, then use the official safety routes below for the market that applies to the medicine in hand.

Match five details before using a safety record

  1. Brand and generic nameBoth must match the medicine named by the record.
  2. Dosage form and strengthTablet, capsule, injection, inhaler, patch and eye drop are not interchangeable.
  3. Market and notice dateA record applies only to the country or region and date it names.
  4. Lot, pack and manufacturerRecord these only when the official notice specifically names them.
  5. Current product informationA historical record may have been superseded by the current label.

This checklist only helps organise the right question. It does not create a personal conclusion about stopping, switching, dose, combination or suitability.

This card brings together the medicine-specific product route and 15 market-level official vigilance gateways. It does not mean real-time alerts for this medicine have been searched in every country or region, or that the medicine has a new alert, recall or risk conclusion. Match brand, generic name, dosage form, strength, market and notice date item by item; do not self-stop, switch, increase or reduce use from a headline.

For severe or rapidly worsening symptoms, suspected overdose, a severe allergic reaction, loss of consciousness or another emergency, use local emergency services. Do not wait for an online alert search or change a medicine from this page.

PACK · LABEL · MEDICINE LIST

Six checks for this medicine pack

Use this card to organise questions about ISORDIL (isosorbide dinitrate immediate-release tablets). Keep the exact pack, its current label and the full medicine list together.

  1. Identify the exact product

    ISORDIL is the brand in this record and isosorbide dinitrate immediate-release tablets is the active-ingredient name. Check both with the dosage form (Dosage form and presentation as documented in the linked primary label) and the market on the actual pack.

  2. Read the labelled strength in context

    mg, mcg, mg/mL or a percentage describes the labelled amount in one tablet, capsule, measured volume, spray or other unit. It is not an answer to how many units a person should take.

  3. Check before splitting or opening

    Before splitting, crushing, chewing or opening anything, find an explicit instruction for this exact product in its current label and ask a pharmacist. A score line or a previous pack is not enough by itself.

  4. Put every product on one list

    Include prescriptions, over-the-counter products, eye drops, creams, vitamins, minerals, herbs and supplements. A pharmacist or prescriber needs the whole list before any combination, alternation, switch or stop is considered.

  5. Ask a specific pharmacogenetics question

    Ask which medicine, which gene and what clinical decision a result could change. A gene–drug association does not mean broad genetic testing is needed for everyone and must not be used to change treatment without professional review.

  6. Know when to seek urgent help

    For a suspected overdose, a severe allergic reaction, fainting or difficulty breathing, use the local emergency or poison-information service now. Do not wait for a website reply or alter several medicines to test what caused it.

This card does not calculate a dose, decide whether medicines can be combined, or replace a clinician or pharmacist. Market-specific current labels and the person's full context still need review.

MARKET DOCUMENTS · READ SEPARATELY

Enlarged market leaflets and regulator documents

Each link retains its own market, date, dosage form and document status. These documents support larger-print reading and item-by-item checking; they do not make products, strengths, packs, indications or use between countries or regions interchangeable.

HOW IT WORKS · NOT A TREATMENT PLAN

How isosorbide dinitrate works: venous and arterial dilation reduces cardiac workload

  • An immediate-release oral tablet is still not a rescue medicine; immediate release describes the dosage form and does not guarantee onset rapid enough to abort an acute attack.
  • Continuous exposure can produce tolerance, but professional scheduling language in the label must not become a web-generated individual timetable. Do not self-skip, delay or stop doses to create an interval.
  • Isosorbide dinitrate forms mononitrate metabolites, but that does not make ISORDIL and IMDUR the same product. Ingredient, dosage form, route, release design and label must remain separate.

How to read this record

Read each document in its stated market, date and dosage-form context. A historical record is not a current label and does not support individual medical, substitution or purchasing conclusions.

Keep international and mainland China records separate

This page has a U.S. public history/regulatory archive but no mainland China record for this specific product. That does not establish whether the medicine exists, is approved or is available in mainland China. Verify product identity, dosage form, strength, holder and the current label item by item.

RECORD FAQ

Record questions

Can I take an extra ISORDIL tablet during chest pain?

Do not do this from a website. Oral ISORDIL does not act rapidly enough to abort an acute attack; sudden or worsening chest pain requires the existing emergency plan and local urgent-care pathway.

Does a score mean the tablet can be halved?

A score alone does not decide this. It identifies the exact labelled product on this page; splitting requires the current label, prescription and professional instruction for the product in hand.
