TEMBEXA 100 MG — DIN 02543842
BRINCIDOFOVIR : 100 MG · EMERGENT BIODEFENSE OPERATIONS LANSING LLC · TABLET · wholesale supply in Canada
Health Canada status: RESTRICTED ACCESS
What is TEMBEXA?
TEMBEXA 100 MG contains BRINCIDOFOVIR : 100 MG. It is listed in the Health Canada Drug Product Database under DIN 02543842, held by EMERGENT BIODEFENSE OPERATIONS LANSING LLC, supplied as TABLET for ORAL administration. Health Canada currently lists it as restricted access, status dated 10-Mar-2026. Health Canada lists this DIN as restricted access, so it is not distributed on ordinary commercial terms — supply runs through the specific route and conditions Health Canada has set for it. Nexara Health is a licensed Canadian wholesale distributor (DEL 3-002896-A) and can confirm whether a compliant route exists for your organisation before anything is quoted.
Is there a generic Brincidofovir 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.
Only one market authorization holder has a Canadian DIN containing Brincidofovir — 2 DINs, of which 0 are currently marketed. There is no second Canadian source today, so a supply interruption on this holder has no domestic substitute at the same molecule.
| Market authorization holder | DINs | Marketed | Brand names | Position |
|---|---|---|---|---|
| EMERGENT BIODEFENSE OPERATIONS LANSING LLC | 2 | 0 | TEMBEXA | No marketed DIN |
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.

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.
1 · Same molecule, other Canadian presentations
0 of 2 Canadian DINs for this molecule are currently marketed. Marketed products are listed first.

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.
How can I get it?
Health Canada does not show a current marketing status for this DIN, so availability has to be confirmed before it can be quoted. Nexara will check the register and tell you what can actually be supplied.
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.
