miraDry is FDA-cleared and considered very safe, but some temporary side effects are common and part of the normal healing process. These may include:
-
Swelling and redness in the underarm area (usually lasts a few days to a week)
-
Soreness or tenderness, which can be managed with over-the-counter pain relief
-
Numbness or tingling in the treated area or nearby skin—typically temporary
-
Minor bruising or firmness under the skin that fades over time
Most patients return to normal daily activities within 24 hours. Serious complications are rare, and your provider will review all safety details with you before treatment.
