Underarm Care During GLP-1: Sweat, Odor and Irritation

Reviewing underarm products before or during GLP-1 treatment?

Check the application instructions

For antiperspirant in a hyperhidrosis treatment plan, AAD advises applying it to dry skin before bed and letting it dry completely. Dry skin makes irritation less likely. Follow your product's directions and your dermatologist's plan. [1]

Report irritation or discoloration

AAD says to tell your dermatologist if an antiperspirant causes irritated skin or underarm discoloration. The clinician may suggest spacing applications or changing the formulation. [1]

Keep the product in its intended area

AAD advises against covering the entire body with whole-body deodorant: ingredients can irritate sensitive areas. It specifically cautions against fragranced products in the groin. Unusual or strong odor can warrant a dermatologist's assessment. [2]

These US guidance pages do not establish that GLP-1 treatment caused sweating or skin changes, or that this routine restores appearance. For a rash in a fold, see our skin-fold assessment guide.
