ISOTAMINE 100 MG — DIN 00261270
ISONIAZID : 100 MG · BAUSCH HEALTH, CANADA INC. · TABLET · wholesale supply in Canada
Health Canada status: DORMANT
What is ISOTAMINE?
ISOTAMINE 100 MG contains ISONIAZID : 100 MG. It is listed in the Health Canada Drug Product Database under DIN 00261270, held by BAUSCH HEALTH, CANADA INC., supplied as TABLET for ORAL administration. Health Canada currently lists it as dormant, status dated 07-Dec-2020. Nexara Health is a licensed Canadian wholesale distributor (DEL 3-002896-A). This DIN is not currently being marketed in Canada, so it is sourced to order where a compliant route exists rather than held in stock.
What is ISOTAMINE used for?
Isoniazid is used in conjunction with at least one other antituberculosis agent in the treatment of clinical tuberculosis and other mycobacterial diseases. It is also used for the prevention of tuberculosis in various at-risk populations, including household contacts of infected individuals, those with significant Mantoux tuberculin skin test reactions, and individuals with certain medical conditions or immunosuppression.
Authorized indication as written in the Health Canada product monograph. For healthcare professionals and licensed purchasers; this is not medical advice.
How much does Isoniazid cost around the world?
Isoniazid is listed on 9 of the national price registers Nexara ingests. Each country publishes on a different basis, so those figures are not comparable with one another — or with a Canadian wholesale price.
What a market publishes matters more than the number it publishes. Australia publishes a ex-manufacturer; Austria publishes a KVP (Kassenverkaufspreis); Czechia publishes a max producer price (ex-factory). Comparing an ex-factory ceiling against a pharmacy public price tells you nothing about either, and comparing either against a Canadian landed cost tells you less.

| United States | acquisition | 2 | 12 | USD███.██ |

49 pack listings across 32 brand entries and 9 price bases, refreshed 08 Sep 2026. Ranges span every Isoniazid pack in that market, so a high figure is usually a larger pack rather than the same product.
Canada publishes no comparable public list price. For a delivered Canadian price on a licensed account, verify your licence — it takes about a minute.
Is there a generic Isoniazid in Canada, and who makes it?
Every market authorization holder with a Canadian DIN for this molecule, and how many of their listings Health Canada currently shows as marketed.
7 holders have a Canadian DIN containing Isoniazid, across 18 DINs, of which 3 are currently marketed. Marketed count is the number that matters: an approval that is not marketed cannot be bought.

Health Canada’s Drug Product Database does not flag which listing is the originator and which are subsequent-entry products, so Nexara does not label them here. Interchangeability is determined provincially, not federally — confirm for your province before a formulary switch. Nexara can confirm which of these is actually obtainable, and on what lead time, per order.
How is it supplied and stored?
Pack configuration, storage class and the handling constraints that drive cold-chain planning. One DIN can cover more than one pack size, and the pack — not the DIN — is what gets priced, shipped and invoiced.
| Strength on the label | 100 MG |
|---|---|
| Dosage form | TABLET |
| Route | ORAL |
| Pack configuration (monograph) | ISOTAMINE Tablets: Bottles of 100 and 1000 tablets. ISOTAMINE Syrup: Bottles of 500 mL. ISOTAMINE Powder: Each bottle contains: 500 g powder. |
| Storage | Isoniazid tablets should be stored in well-closed, light-resistant containers at controlled room temperature (15 - 30 °C). When stored in filled unopened containers at a temperature not exceeding 25 °C, the syrup is expected to retain its potency for 1 year. |
Before an order line is unambiguous Nexara needs the strength, the pack size and the presentation.

Health Canada record and identifiers
The regulatory facts straight from the Drug Product Database, plus every identifier form Nexara accepts on a purchase order. A DIN written without its leading zeros is the commonest reason an order line fails to match.

What can be used instead?
Alternatives on every axis a buyer actually considers — the same molecule in another presentation, the same class, an adjacent class, or a fixed-dose combination. Every row is led by the marketed DIN count, because that is what can be bought this week.

A molecule with zero marketed DINs cannot be sourced domestically, however many approvals it holds — if one of these sits on a formulary or in an older protocol, that is the line to check.

Not clinical advice. These tables describe what can be supplied in Canada, not what should be prescribed. Substitution within or across classes is a prescriber and pharmacist decision, and interchangeability is determined provincially.
What else is ISOTAMINE called?
The same molecule, Isoniazid, is registered under other names elsewhere. Buyers and prescribers searching from outside Canada — or working from a foreign prescription or tender document — often know it by one of these:
| Name | Script | Registered in |
|---|---|---|
| Arrow Pharma Pty Ltd | Latin | Australia |
| Be-Tabs Isoniazid | Latin | South Africa |
| I.N.H | Latin | Saudi Arabia |
| Solonex Co | Latin | South Africa |
Names are taken from national medicine registers and published price lists. A product registered abroad is not authorized for sale in Canada unless it holds its own DIN; import is possible only through the routes Health Canada permits.
How can I get it?
This DIN is dormant — it holds a Health Canada authorization but is not currently being marketed in Canada, so it cannot simply be ordered from Canadian stock. Where a patient need exists, supply may be possible through exceptional importation or the Special Access Programme, subject to Health Canada's requirements and the prescriber's application. Nexara can advise on the route and on marketed alternatives.
Ordering questions
Who can buy this from Nexara?
Licensed entities only. Nexara holds Health Canada establishment licence DEL 3-002896-A and ships only to a licensed address. Patients and unlicensed buyers are routed to a partner pharmacy.
Is there a minimum order?
Yes, set per product line and per pack multiple rather than on the order total, so you are never asked to buy a part-pack. The minimum for this line is confirmed with your quote.
What is the lead time?
Confirmed per order at quotation, and it depends on current stock position and whether the product is in shortage.
Why is there no price on this page?
Nexara quotes a delivered Canadian price per order, against a verified licence. Foreign list prices are published on incompatible bases and are not a guide to what any buyer can obtain here, so this page shows which markets list the molecule and on what basis, and nothing more.
Can Nexara supply this for a clinical trial?
Yes — comparator and background-therapy supply, including sourcing from other markets where a Canadian pack will not satisfy the protocol. Clinical trial supply.
