What if prescription antiperspirant does not relieve body odour?

Antiperspirant reduces sweat reaching the skin, but odour can also involve skin bacteria, trapped moisture, clothing, hair-bearing areas or a separate skin problem. The product may have been applied at the wrong time, used too infrequently, or stopped because of irritation. Odour that continues despite less sweating may therefore need a different approach rather than simply more product.

Review the prescribed directions and tell your clinician whether sweating changed, whether odour is present from one area or several, and whether the skin became sore. Do not apply extra product to broken or inflamed skin. Keep affected areas clean and dry, change damp clothing, and wash garments that retain odour. A clinician can examine the skin and decide whether to adjust the antiperspirant, address irritation, or investigate another contributor.

Seek prompt medical advice for a sudden unexplained change in body odour, a painful rash, spreading redness, drainage, fever, or a new lump. These findings can indicate a skin infection or another condition requiring examination. Arrange routine follow-up when odour persists, returns quickly after washing, or affects daily activities despite following the treatment plan.

Could the odour be coming from a skin condition rather than sweat alone? Should the application schedule or product be changed? What signs of irritation or infection should I watch for?
