What is Qbrexza?

Qbrexza (glycopyrronium cloth) is used on underarm skin to treat excessive sweating (hyperhidrosis) in adults and children who are at least 9 years old.

Qbrexza may also be used for purposes not listed in this medication guide.

Tell your doctor if you are pregnant or breast-feeding.

How should I use Qbrexza?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Apply only to clean, dry underarm skin. Do not use on open wounds or broken skin.

Do not cover treated skin with a bandage or with plastic.

Use a single Qbrexza cloth on both underarms once every 24 hours. Then throw the cloth away.

Wash your hands after handling a Qbrexza cloth. Any medicine left on your hands could cause blurred vision if you later touch your eyes.

Keep each cloth in the sealed pouch until it is time for you to apply the medicine.

Glycopyrrolate cloths are flammable. Do not use near high heat or open flame.

What happens if I miss a dose?
