Who else supplies ISONIAZID worldwide?

Nexara tracks national medicine registries and published price lists across multiple markets. ISONIAZID appears in 683 registered pack listings across 10 markets, published on 10 different national price bases. Where a Canadian route is closed, that is where an alternative route of supply starts — subject to the import rules in both countries.

Registered listings are not stock. Ask us to confirm what can actually be sourced for your order.

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.

If you are looking for a current equivalent, the alternatives above list every product sharing this therapeutic class, with the marketed ones first. Ask us to source an alternative

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.

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.

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.
