If your pharmacy has told you that your Dotti (estradiol) patch is on backorder, you are not alone. Throughout 2026, estradiol transdermal patches have been in short supply across much of North America, and the shortage extends well beyond Dotti to many other patch brands and generics. This article explains what is happening, what alternatives exist, and practical steps you can take to keep your hormone therapy on track. As always, work with your own doctor and pharmacist before making any change.
What’s Going On
Dotti (estradiol transdermal patch, made by Amneal Pharmaceuticals) is in an active, well-documented shortage in the United States. Several strengths are on backorder with no firm restock date, and other manufacturers of estradiol patches are affected too. The disruption is being driven by a combination of factors:
– A sharp rise in demand. Prescriptions for hormone therapy have climbed steeply, particularly after the U.S. FDA removed the long-standing “black box” warning from menopausal hormone therapy products in late 2025. Newer research has reassured many patients and prescribers about the safety of HRT when started near menopause.
– Limited manufacturing capacity. Only a handful of companies make estradiol patches, and several were already operating near capacity when demand surged. Supply chain and production constraints have made it hard to scale up quickly.
Most industry observers expect the tight supply to persist into late 2026. It’s worth noting that this is primarily a U.S. situation; supply status in Canada and the UK is tracked separately and differs by brand and strength.
Options to Discuss With Your Doctor
The right choice depends on your health history, current dose, and whether your therapy also needs to include a progestogen to protect the uterine lining. Bring these possibilities to your prescriber:
– Switch to a different patch brand or generic. Several manufacturers make estradiol patches. If one brand is unavailable, another may be in stock. Patches are not always directly interchangeable in size or dosing schedule, so your prescriber will match the strength appropriately.
– Switch delivery method. Estradiol gels, creams, and sprays deliver the same hormone through the skin and are often more readily available (see below).
– Adjust the wear schedule only under guidance. Do not stretch a patch beyond its intended wear time or cut a patch to make supply last. With Dotti in particular, cutting can affect how the drug is delivered. Any change to how you use your patch should come from your prescriber.
– Don’t stop abruptly. Suddenly discontinuing estradiol can cause a rapid return of symptoms such as hot flashes and night sweats. If you’re running low, contact your prescriber before you run out.
Patch Brands Available in Canada
Canada has its own set of approved estradiol patches, and the brand names differ from the U.S. Patches available in Canada include:
– Estradot (twice-weekly; strengths of 25, 37.5, 50, 75 and 100 mcg/day) — this is the Canadian equivalent of Dotti and Vivelle-Dot: the same small, twice-weekly patch, sold under a different brand name
– Climara (once-weekly; strengths including 25, 50, 75 and 100 mcg/day)
– Sandoz Estradiol Derm (generic; twice-weekly) – note that this is a larger patch, and some patients find it adheres less reliably; applying to clean, dry skin and rotating sites can help
– Estraderm / Estraderm MX (twice-weekly)
Combination patches that also contain a progestogen (for those who need both hormones) are marketed in Canada as well, such as Estalis.
Patch Brands Available in the UK
The UK also has a distinct lineup of estradiol patches. Estrogen-only patches available there include:
– Evorel (twice-weekly; 25, 50, 75 and 100 mcg)
– Estraderm MX (twice-weekly; 25, 50, 75 and 100 mcg)
– FemSeven Mono (once-weekly; 50, 75 and 100 mcg)
– Estradot (twice-weekly; also sold in the UK)
Note that UK supply is also under pressure: at the time of writing, several strengths of Estradot in the UK have been subject to shortage protocols, while Evorel, Estraderm MX and FemSeven have generally been available to absorb demand. Availability changes frequently, so any specific brand should be confirmed as in stock at the time of ordering.
Mail Order From Outside the U.S.
Because Canada and the UK stock estradiol patches under different brand names and their supply situations don’t always mirror the U.S., ordering from a licensed international or Canadian pharmacy can be a practical way to obtain supply when a product is backordered domestically. A few points to keep in mind:
– Use a licensed, reputable pharmacy that requires a valid prescription. A legitimate Canadian pharmacy will always ask for one.
– Your prescription may need to specify the international brand name (for example, Estradot or Evorel) and an equivalent strength, so ask your prescriber to write it accordingly.
– Allow extra lead time for shipping, and order before you run low so a delay doesn’t interrupt your therapy.
– Confirm the specific product and strength are in stock at the time you order, since availability shifts week to week.
Gels, Creams and Sprays as Alternatives
If patches remain hard to find, non-patch transdermal estradiol delivers the same hormone through the skin and is frequently in better supply. Options to raise with your doctor include:
– Gels (for example, Oestrogel or Sandrena sachets)
– Sprays (for example, Lenzetto)
– Creams
These bypass the digestive system much like a patch does, and your prescriber can convert your patch dose to an equivalent gel, spray, or cream dose. As with patches, your therapy will generally also need to include a progestogen to protect the uterine lining unless you’ve had a hysterectomy.
How to Stay Updated on Supply and Backorders
Supply status changes frequently. To keep current:
– In Canada: ** Check *Drug Shortages Canada* (drugshortagescanada.ca), the official reporting site where manufacturers post backorder and discontinuation notices.
– In the U.S: ** The **ASHP** (American Society of Health-System Pharmacists) drug shortage bulletin and the **FDA** drug shortage database track affected products and estimated release dates.
– In the UK: ** Medicine Supply Notifications and Serious Shortage Protocols are issued through the NHS and the Department of Health and Social Care.
– Ask your pharmacist. Your pharmacy team sees real-time wholesaler availability and manufacturer backorder notices, and can often tell you which brand or strength is currently obtainable and arrange a switch with your prescriber.
