What causes excessive sweating (hyperhidrosis)?

Sweating is controlled by the central nervous system, which sends signals to sweat glands on the skin. The sweat glands are normal in people with hyperhidrosis, but the signaling from the central nervous system works overtime. From avoiding social engagements to sweating through shirt after shirt—it can be very disruptive to one’s social life, career, and overall emotional health.

How does hyperhidrosis treatment with Ro work?

We use telemedicine technology to connect you with a U.S. licensed doctor to provide hyperhidrosis treatment conveniently and affordably.

It starts with your online doctor visit. Your doctor needs to know about your general health and how excessive sweating affects you.

They also need an unedited photo of you and your ID (that shows your picture and birthdate) so they know who they will be helping, as well as a photo of the affected area(s) to confirm the diagnosis. They review everything, determine if you’re a candidate for telemedicine and whether treatment is right for you, and if so, they will send you a personalized treatment plan.

Their treatment plan will include a great deal of information about hyperhidrosis. It is important that you take the time to read it all to be informed and better prepared to manage your condition.

If you qualify, your doctor will prescribe the right course of treatment to help you take control of your hyperhidrosis.

What causes hyperhidrosis?

Sweating is controlled by the central nervous system, which sends signals to sweat glands on the skin. Sweating is normal when it happens in response to physical exertion, or if your body senses a threat and goes into “fight or flight” mode. However, the kind of excessive sweating seen in hyperhidrosis is much more than usual, and can be very disruptive to everyday life. The sweat glands are normal in hyperhidrosis, but the signalling from the central nervous system is abnormal. There may be some influence from genetics which is not very well understood.

What medication do you prescribe for hyperhidrosis?

If a prescription is appropriate, Ro-affiliated physicians may prescribe 20% aluminum chloride hexahydrate (Drysol), a prescription antiperspirant that works by blocking the sweat glands. Aluminum-containing antiperspirants are recommended for hyperhidrosis by the American Academy of Dermatology. 

Not everyone should use Drysol. To learn more about side effects and contraindications, see “What are the side effects of hyperhidrosis treatment” below and read Important Safety Information for aluminum antiperspirant.

Can I get treatment if I haven’t been diagnosed with hyperhidrosis by a doctor before?

Many people don’t realize that hyperhidrosis is a treatable condition, so it’s okay if you haven’t previously seen a doctor or healthcare provider for your excessive sweating before. Your Ro-affiliated doctor will collect information about your medical history and your excessive sweating symptoms via telemedicine. If hyperhidrosis is diagnosed and treatment is appropriate for you, your doctor will make a recommendation and prescribe the treatment.

Is hyperhidrosis treatment effective?

Aluminum antiperspirant is considered the standard prescription treatment for hyperhidrosis for people who have tried over-the-counter antiperspirants. If you’ve been using prescription antiperspirant as directed and aren’t satisfied with the results, you can reach out to your Ro-affiliated doctor at any time to discuss.

Not everyone should use Drysol. To learn more about side effects and contraindications, see “What are the side effects of hyperhidrosis treatment” below and read Important Safety Information for aluminum chloride hexahydrate.
