Is there a generic Vaginal Ring With Progestogen And Estrogen 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.
3 holders have a Canadian DIN containing Vaginal Ring With Progestogen And Estrogen, across 3 DINs, of which 3 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 |
|---|---|---|---|---|
| DUCHESNAY INC | 1 | 1 | RINGZA | Sourceable in Canada |
| ORGANON CANADA INC. | 1 | 1 | NUVARING | Sourceable in Canada |
| SEARCHLIGHT PHARMA INC | 1 | 1 | HALOETTE | Sourceable in Canada |
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.

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
3 of 3 Canadian DINs for this molecule are currently marketed. Marketed products are listed first.

| Molecule | Canadian brands | DINs | Marketed | Sourceable |
|---|---|---|---|---|
| Vaginal Ring With Progestogen And Estrogen | HALOETTE · NUVARING · RINGZA | 3 | 3 | Yes |
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 G02B
| ATC subgroup | Molecules | DINs | Marketed |
|---|---|---|---|
| G02BA | Plastic Iud With Progestogens | 3 | 2 |

How can I get it?
Nexara Health supplies this product to licensed Canadian buyers — pharmacies, hospitals, clinics, licensed distributors, and clinical trial sponsors or their CROs. We confirm stock, pack size, expiry and pricing at the time of quotation. If the product is on backorder or in shortage, we identify equivalent alternatives and import options where permitted.
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.
