DARAPRIM 25 MG — DIN 00004774
PYRIMETHAMINE : 25 MG · AMEDRA PHARMACEUTICALS LLC · TABLET · wholesale supply in Canada
Health Canada status: CANCELLED POST MARKET
What is DARAPRIM?
DARAPRIM 25 MG contains PYRIMETHAMINE : 25 MG. It is listed in the Health Canada Drug Product Database under DIN 00004774, held by AMEDRA PHARMACEUTICALS LLC, supplied as TABLET for ORAL administration. Health Canada currently lists it as cancelled post market, status dated 01-Jun-2013. 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.
What is DARAPRIM used for?
Treatment of acute malaria (conjointly with fast-acting schizonticides) and treatment of toxoplasmosis (conjointly with a sulfonamide).
Authorized indication as written in the Health Canada product monograph. For healthcare professionals and licensed purchasers; this is not medical advice.
How much does Pyrimethamine cost around the world?
Pyrimethamine is listed on 3 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. Saudi Arabia publishes a public; South Africa publishes a single exit price; United States publishes a acquisition. 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 |
|---|---|---|---|---|
| United States | acquisition | 1 | 6 | USD███.██ |
| South Africa | single exit price | 2 | 2 | ZAR███.██ |
| Saudi Arabia | public | 1 | 1 | SAR███.██ |
9 pack listings across 4 brand entries and 3 price bases, refreshed 03 Sep 2026. Ranges span every Pyrimethamine 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.
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 | 25 MG |
|---|---|
| Dosage form | TABLET |
| Route | ORAL |
| Pack configuration (monograph) | Bottles of 50 tablets. |
| Storage | Store between 15° to 30°C and keep dry. |
Pack detail is kept as a regulatory record. This DIN is no longer authorized for sale in Canada, so Nexara does not quote this pack.

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.

How is it administered?
Malaria: 25-75mg depending on age/weight. Toxoplasmosis: Adults 50mg initial then 25mg daily. Must be used with a sulfonamide and folate supplement. Treatment duration 3-6 weeks.
Included because it drives pack selection and wastage. Consult the monograph.
Contraindications
Contraindicated in patients with a history of hypersensitivity to pyrimethamine or to any component of the preparation.
Warnings and precautions
Co-administration of folate supplement is necessary to reduce bone marrow depression. Weekly blood counts required. Keep out of reach of children (accidental ingestion can be fatal).
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.
2 · Same class — other molecules in ATC P01BD
| Molecule | Canadian brands | DINs | Marketed | Sourceable |
|---|---|---|---|---|
| Pyrimethamine | DARAPRIM | 1 | 0 | Not in Canada |
| Pyrimethamine, Combinations | FANSIDAR TABLETS | 1 | 0 | Not in Canada |
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.
3 · Adjacent classes in ATC P01B
| ATC subgroup | Molecules | DINs | Marketed |
|---|---|---|---|
| P01BA | Chloroquine · Hydroxychloroquine · Primaquine | 15 | 7 |
| P01BB | Proguanil · Proguanil And Atovaquone | 8 | 6 |
| P01BC | Mefloquine · Quinine | 21 | 5 |
| P01B | Antimalarials | 1 | 0 |
| P01BX | Halofantrine | 1 | 0 |
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 DARAPRIM called?
The same molecule, Pyrimethamine, 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 |
|---|---|---|
| Fansidar | 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.
