Statuses checked October 18, 2026 against each row's source. We re-check every week.

Patches of the same strength from different makers are not all alike: some are changed once a week and some twice, and the sizes differ. Your pharmacist can tell you which ones your prescription allows, and your prescriber has to agree any change of strength or form.

How to read the answer

Available
The source (ASHP for the US, Drug Shortages Canada or the maker) doesn't list it as short. Not a promise your pharmacy has a box today.
Limited
Some supply is getting through, often on allocation or with weekly releases.
Short
On back order, usually with no release date.
No data
No source we could read gives a status. It may still be short.

Every row on the US status board and the Canada board names its source and the date we read it. Each strength also has its own page, for example the 0.05 mg page.

If the finder says it's out

The question to take to the pharmacy is whether they can order a different maker's patch in the same strength, and whether your prescription lets them. In the US that depends on how the FDA rates the patches against each other and on your state's substitution law; in Canada it depends on the province. What to ask the pharmacy goes through it step by step, and switching brands covers the once-a-week and twice-a-week difference.
