The short answer
Clinical strength (10–20% aluminum) is the strongest OTC option — enough for most heavy sweaters. Prescription antiperspirant (typically 20% aluminum chloride hexahydrate / Drysol) is the next step when clinical strength stops working. If clinical strength doesn't keep you dry, it's time to talk to a doctor.

When to step up to prescription
- You've used clinical strength nightly for 4+ weeks with no improvement
- You still sweat through shirts on normal days
- Sweating disrupts work, dating, social life, or sleep
- You have visible sweat marks in cool weather
How to apply prescription antiperspirant correctly
- Apply to completely dry skin at bedtime — wetness causes irritation.
- Cover the entire underarm with a thin layer.
- Wash off in the morning with mild soap.
- Use 2–3 nights weekly for the first 2 weeks, then taper to 1–2 nights as needed.
- Hydrocortisone 1% can be used short-term if irritation develops.
