Is the Brella Sweat Patch Still Available?What the Trial Found
Odor & SweatArticleAn October 2026 availability notice changes the practical question. The trial's headline result also needs its analysis population attached.

In this article
Before arranging a Brella consultation, check the date on the information you found. In its October 2026 update, the International Hyperhidrosis Society1 says Brella is no longer available. It reports no further information about the sale of Candesant Biomedical, the company behind it, and no contact for updates.1
That notice concerns supply. The FDA’s2 device review concerns authorization and clinical evidence. An old treatment page can describe an authorized procedure without establishing that a clinic can provide it today.
What kind of patch was Brella?
A prescription office treatment for adults with primary underarm hyperhidrosis. Sodium reacts with sweat to generate heat. Clinicians remove the patch within three minutes and clean the skin. The FDA2 review did not establish safety and effectiveness for repeated use or other body sites.2
Did it beat a sham patch?
In the published per-protocol analysis, yes: at four weeks, 28 of 44 treated participants (63.6%) reached a Hyperhidrosis Disease Severity Scale score of 1 or 2, versus 19 of 43 (44.2%) with sham. Those scores mean unnoticed or tolerable sweating, not complete dryness.23
The study included 110 randomized participants plus ten initial safety participants who all received active treatment. The safety participants were outside the randomized comparison. Candesant sponsored the study, supplied the devices and paid the study team.3
Why does the analysis population matter?
The FDA2 review also reports the prespecified full-analysis result: 30 of 51 (58.8%) versus 29 of 55 (52.7%), a difference that was not statistically significant. Twenty participants were excluded from the per-protocol population because they were taking medicines that could alter sweating.2
The favorable subset result needs that qualification: the primary comparison did not succeed across the broader analysis population. Bring a complete medicine list to your consultation. Do not stop prescribed treatment to qualify for a procedure.
Did one application last permanently?
No. The paper reports that 48% had not returned to their starting severity score at three months and 43% maintained that effect at four months. Staying below the starting score isn’t the same outcome as maintaining a score of 1 or 2. The trial did not compare Brella directly with botulinum toxin or microwave treatment.3
What should I ask a clinic advertising it now?
Ask whether its Brella page reflects current supply, which treatment it can provide today, and whether any quoted price includes follow-up. An unanswered supply question is a reason to postpone payment.
For the broader consultation, Arms Up includes “The Step-Up Conversation,” covering treatment comparisons, duration, side effects and ongoing costs. The underarm patch treatment guide covers suitability and skin-care questions; read it alongside the current availability notice.
