How long does botox for sweating take to work for bromhidrosis?

Bromhidrosis is unpleasant body odour that can develop when skin secretions interact with microorganisms. Reducing sweat may reduce moisture that supports odour, but it does not remove every possible source. Skin folds, hair, infection, clothing, medicines, and other health conditions may influence the smell. Botulinum toxin is a targeted treatment for sweating, not a complete explanation for new or persistent odour.

Keep the area dry, wash gently, change damp clothing, and follow the clinician’s advice about antiperspirant or other products. Avoid harsh scrubbing, which can irritate skin. Record whether moisture, odour, rash, or tenderness changes separately. A clinician can check for infection or another cause if odour continues after sweating has reduced.

Arrange medical advice for a sudden change in body odour, painful lumps, rash, open skin, pus, fever, or redness that spreads. Seek urgent help for breathing or swallowing difficulty, severe weakness, or rapidly worsening symptoms after injections. Persistent odour with little sweating should be reassessed rather than treated with repeated injections automatically.

Ask whether sweating is the main driver of your odour, when improvement should be judged, how skin infection will be excluded, and what hygiene or prescription options can be combined safely.
