Health Canada status: CANCELLED POST MARKET
What is ISONIAZID SYRUP 50MG/5ML?
ISONIAZID SYRUP 50MG/5ML 50 MG / 5 ML contains ISONIAZID : 50 MG / 5 ML. It is listed in the Health Canada Drug Product Database under DIN 00722464, held by CAROLINA MEDICAL PRODUCTS COMPANY, supplied as SYRUP for ORAL administration. Health Canada currently lists it as cancelled post market, status dated 26-Jul-1999. This Drug Identification Number is no longer authorized for sale in Canada, so Nexara does not supply it. The record is kept here because buyers still meet the number on old formularies, purchase orders and tender documents; Nexara can help identify an authorized alternative.
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.
| Market | Price basis published there | Brands | Packs listed | Range |
|---|---|---|---|---|
| South Africa | single exit price | 16 | 19 | ZAR███.██ |
| United States | acquisition | 2 | 12 | USD███.██ |
| Romania | max producer price | 4 | 8 | RON███.██ |
| Saudi Arabia | public | 4 | 4 | SAR███.██ |
| United Kingdom | hospital | 2 | 2 | GBP███.██ |
| Austria | KVP (Kassenverkaufspreis) | 1 | 1 | EUR███.██ |

| Czechia | max producer price (ex-factory) | 1 | 1 | CZK███.██ |
| Greece | producer price (ex-factory) | 1 | 1 | EUR███.██ |
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.
This table is a regulatory record of where the molecule is listed. The DIN on this page is no longer authorized for sale in Canada, so Nexara does not quote it — see the alternatives above.
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 | 50 MG / 5 ML |

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 ISONIAZID SYRUP 50MG/5ML 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.
Can this still be bought in Canada?
No. This Drug Identification Number is cancelled post market in Health Canada's Drug Product Database, so the product is no longer authorized for sale in Canada and Nexara does not supply it. This page is kept as a regulatory record.

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.
