EXPERT ANALYSIS FROM SDEF LAS VEGAS DERMATOLOGY SEMINAR

 

LAS VEGAS – Be alert for hidden cases of hyperhidrosis in patients, Seemal R. Desai, MD, said during a presentation on this topic at Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.

During an examination for another condition, he said, patients may be “sweating and dripping.” However, “you look over that diagnosis because that’s not what they’re there for,” said Dr. Desai, a dermatologist at the University of Texas Southwestern Medical Center in Dallas.

He described one of his patients, who only revealed that she suffered from “horrible, devastating” hyperhidrosis after he’d treated her for years for melasma. The sweating especially affected her because it prevented her from wearing the skin-exposing clothing of her Indian culture.

Delays in treatment are common in hyperhidrosis, which is believed to affect 5% of the world’s population. According to Dr. Desai, research suggests that 85% of patients with hyperhidrosis wait more than 3 years to bring it up with doctors, and half wait more than a decade.

There are many treatments for hyperhidrosis. Some are fairly simple: over-the-counter or prescription antiperspirants, said Dr. Desai, who likes the over-the-counter brand Certain Dri), iontophoresis (application of electric current), topical anticholinergics (including glycopyrronium tosylate cloth wipes, recently approved by the FDA for topical treatment of primary axillary hyperhidrosis for ages 9 years and older), and systemic management. Others are minimally invasive: Botox injections and the miraDry medical device (which relies on thermolysis). And surgical strategies may be an option for severe cases.

On its website, the International Hyperhidrosis Society provides a chart of options for hyperhidrosis in various parts of the body. Treatments tend to focus on the underarms, however, and “we’ve got huge unmet needs for patient options,” Dr. Desai said.

  • During his presentation, he provided the following pearls regarding hyperhidrosis treatments:
  • Distinguish between antiperspirants, which block sweating, and deodorants, which cover up body odor. “Sometimes I get caught up in the middle of a busy office visit and use these terms interchangeably. They’re really different, but patients and the public tend to equate those together,” he commented.
  • Make sure patients understand how to properly use antiperspirants and explain that antiperspirants must be applied to dry skin. “Antiperspirant is forming a clog in the drain” to prevent the release of sweat, he said. “If you apply it to wet skin, you will block that chemical reaction in the duct.”
  • Massage in the antiperspirant, he advises, and don’t occlude the skin. Apply twice daily, including before bedtime. “They can use antiperspirant on the hands and the bottom of the feet,”Dr. Desai said. “You want to ensure that they’re using the spray on the surface and in the web space. They can also use antiperspirants on the face, but avoid contact with the eyes.”
  • Be careful if you prescribe glycopyrronium cloths off label. These wipes are helpful and they can be used outside the FDA-approved use in the underarms, said Dr. Desai, who said he has palmar hyperhidrosis and has successfully used them on his palms, but he hasn’t found them to be helpful on the soles of his feet.

Dr. Desai recommends 5-minute applications on the palms because the treatment can irritate the face and eyes.

Linda F. Stein Gold, MD, of Henry Ford Health System in Detroit, told the audience about the case of a teacher who touched his eyes after applying the treatment. He went to school, felt ill, and ended up in an emergency department because he had an enlarged pupil. “You just have to tell people this can happen,” she said.

Dr. Desai reported no relevant disclosures.
