How quickly does prescription antiperspirant relieve excessive sweating?

Aluminium chloride moves into sweat ducts and forms a temporary blockage near the skin surface. This lowers the amount of sweat released from treated areas; it does not change the body's ability to sweat elsewhere. Improvement can therefore be gradual and uneven.

Underarms, hands, feet, and other areas may need different instructions. The strength and frequency chosen by a clinician also depend on your skin and the severity of sweating.

Follow the prescription label closely and apply to dry, intact skin. Night-time application is often advised because sweating is lower, but use the schedule given to you. Wash the area as directed before daytime activities, and do not apply immediately after shaving.

Once sweating is controlled, your clinician may move you to less frequent maintenance applications. Moisture-wicking clothing and absorbent footwear can make daily symptoms easier while treatment takes effect.

Contact your clinician if there is no meaningful improvement after the prescribed trial, or if treatment causes persistent burning, cracking, swelling, or a rash. Seek prompt medical care for sudden widespread sweating with chest discomfort, faintness, confusion, or severe illness.

Ask when to judge the first response, how long to leave the product on, and how to protect sensitive skin. Ask whether sweating in new areas or during sleep changes the evaluation.
