New treatment coming for excessive sweating

RENO, Nev. (KOLO) - The heat is on. But for patients with hyperhidrosis, it's not just heat that makes them sweat. It can be under any condition.

“I notice it in the winter and the summer. Even when I am cooled and I have goose bumps and I’m still sweating,” says Sarah Bajenski, a hyperhidrosis patient.

We followed Sarah as she underwent painful Botox injections. At the time it was one of the only options for patients with hyperhidrosis.

“It is about 60 70 tiny injections into the lower layer of skin. And so you have to repeatedly do that. So it is a little cumbersome. People have to come in. Insurance companies haven't been real good about paying for it. And it is exceedingly expensive,” says Dr. Cindy Lamerson, MD, a dermatologist with Nevada Center for Dermatology.

The Food and Drug Administration has approved a new topical wipe. Used once a day, it will help curtail sweating. Called Qbrexza, it can be used on patients nine years or older.

Dr. Lamerson points to a model showing a cross section of the skin.

“This drug inhibits the nerve... the nerves go to the eccrine glands and they are parasympathetic nerves. And they stimulate the gland to produce sweat. The topical medication will inhibit those nerves. So there will be no stimulation to this gland and consequently no sweat,” says Dr. Lamerson.

Possible side effects include dry skin, mouth, nose, throat and eyes. Headaches, blurred vision, dilated pupils, constipation and trouble urinating are other side effects listed.

The drug is expected to hit the market in October; the cost has not been released, and we don't know if it will be picked up by insurance.
