Key takeaways
Qbrexza (glycopyrronium) and Botox (onabotulinumtoxinA) are both used to treat excessive underarm sweating, but they have some key differences. Qbrexza is an anticholinergic medication that you apply topically to your underarms using a towelette, while Botox is a neuromuscular blocker that must be injected by a healthcare professional. You use Qbrexza once every 24 hours. In contrast, Botox is typically administered every three months. Qbrexza is only available as a brand-name medication and can be expensive, whereas Botox is also brand-only and might be costly. Additionally, Botox has a broader range of uses, including treating muscle spasms, bladder problems, and preventing migraines, while Qbrexza is only approved for underarm sweating. Both medications have side effects, but Botox can have serious risks if the toxin spreads to other parts of your body.
