Medical antiperspirants are prescription products used as first-line treatment in individuals with excessive sweating. Formulations containing aluminium chloride and glycopyrrolate reduce the activity of sweat glands to bring hyperhidrosis symptoms under control.
What Is a Medical Antiperspirant?
Medical antiperspirants differ from cosmetic products in that they contain a higher concentration of active ingredient. While standard deodorants contain 1–2% aluminium salts, medical formulations have concentrations of 15–25% aluminium chloride hexahydrate or 20% aluminium chloride.
These products physically reduce sweating by temporarily plugging sweat ducts. Duration of effect may range from 24 to 72 hours, and efficacy increases with regular use.
Aluminium Chloride Formulations
Aluminium chloride is the most widely used active ingredient in medical antiperspirants. It is applied to dry skin at bedtime and washed off in the morning. Daily application is recommended for the first few weeks, followed by 2–3 times per week. Ethanol-based formulations are more effective but carry a higher risk of skin irritation.
Topical Glycopyrrolate Treatment
Glycopyrrolate is an anticholinergic agent. Its topical formulations are particularly effective for facial and scalp sweating. It inhibits eccrine sweat gland stimulation by blocking acetylcholine receptors. It is available as a wipe or cream.
- 2% glycopyrrolate wipes are effective for facial sweating
- Washing hands after application is recommended
- Dry mouth and blurred vision may occur as side effects
Usage Guide and Tips
The efficacy of medical antiperspirants is directly related to correct application. It is important to apply the product at bedtime to dry, clean skin. Because sweat glands are at rest overnight, penetration of the active ingredient is more effective during this period.
A mild burning or itching sensation may be felt during initial applications; this typically subsides within a few days. The product should not be applied to freshly shaved or irritated skin.
Side Effects and Alternatives
The most common side effect is skin irritation. In such cases, switching to a lower-concentration formulation or reducing the frequency of application is recommended. In patients who do not respond to medical antiperspirants, alternatives such as botulinum toxin injections, iontophoresis, or oral anticholinergic therapy should be considered.
