RIVA-DAPSONE 100 MG — DIN 02489058
DAPSONE : 100 MG · LABORATOIRE RIVA INC. · TABLET · wholesale supply in Canada
Health Canada status: DORMANT
What is RIVA-DAPSONE?
RIVA-DAPSONE 100 MG contains DAPSONE : 100 MG. It is listed in the Health Canada Drug Product Database under DIN 02489058, held by LABORATOIRE RIVA INC., supplied as TABLET for ORAL administration. Health Canada currently lists it as dormant, status dated 22-Jul-2024. 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 RIVA-DAPSONE used for?
RIVA-DAPSONE is used to treat leprosy, dermatitis herpetiformis (a skin condition), and actinomycotic mycetoma (a fungal disease).
Authorized indication as written in the Health Canada product monograph. For healthcare professionals and licensed purchasers; this is not medical advice.
How much does Dapsone cost around the world?
Dapsone is listed on 5 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; Saudi Arabia publishes a public; South Africa publishes a single exit price. 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 | 4 | 51 | USD███.██ |
| Australia | ex-manufacturer | 3 | 5 | AUD███.██ |
| United Kingdom | hospital | 2 | 2 | GBP███.██ |
| Saudi Arabia | public | 1 | 2 | SAR███.██ |
| South Africa | single exit price | 1 | 1 | ZAR███.██ |
61 pack listings across 11 brand entries and 5 price bases, refreshed 08 Sep 2026. Ranges span every Dapsone 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 Dapsone 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.
5 holders have a Canadian DIN containing Dapsone, across 5 DINs, of which 1 are currently marketed. Marketed count is the number that matters: an approval that is not marketed cannot be bought.
| Market authorization holder | DINs | Marketed | Brand names | Position |
|---|---|---|---|---|
| MARCAN PHARMACEUTICALS INC | 1 | 1 | MAR-DAPSONE | Sourceable in Canada |
| AYERST LABORATORIES | 1 | 0 | AVLOSULFON TAB 100MG | No marketed DIN |
| EVEREST LIFE SCIENCES LLC | 1 | 0 | DAPSONE | No marketed DIN |
| LABORATOIRE RIVA INC. | 1 | 0 | RIVA-DAPSONE | No marketed DIN |
| TARO PHARMACEUTICALS INC | 1 | 0 | TARO-DAPSONE | 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.
| Strength on the label | 100 MG |
|---|---|
| Dosage form | TABLET |
| Route | ORAL |
| Pack configuration (monograph) | bottle of 100 tablets |
| Storage | store at room temperature and protected from light |
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 RIVA-DAPSONE called?
The same molecule, Dapsone, 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 |
|---|---|---|
| DAPSOMED | Latin | Australia |
| Dapsone Tillomed | Latin | Saudi Arabia |
| Dapsone | 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.
