What is prescription antiperspirant done with?

Aluminium chloride is a topical antiperspirant ingredient. Applied to the skin, it forms a temporary blockage within sweat ducts, reducing the amount of sweat that reaches the surface in the treated area. It may be prescribed for underarms, hands, feet, or another area after an assessment.

This is different from a deodorant, which mainly targets body odour. Prescription strength can irritate skin, especially when applied to damp, freshly shaved, broken, or inflamed skin, so the instructions for timing and application matter.

Apply only to the area and schedule advised by the prescriber, often when sweating is lower. Wash and dry the skin thoroughly before use, and keep the product away from eyes and mucous membranes. If burning or irritation develops, ask the prescriber how to adjust use rather than applying more.

Tell the clinician about eczema, cuts, rashes, other skin products, and any previous reaction to antiperspirants. A moisturiser or a different application plan may be recommended if the skin becomes dry or irritated.

Stop and seek medical advice if you develop severe burning, blistering, marked swelling, or a persistent rash. Urgent care is appropriate for facial swelling, breathing difficulty, or a widespread reaction after application.

Ask which aluminium chloride formulation to use, how much to apply, when to wash it off, and what to do if sweating continues or the skin becomes irritated.
