Anhydrol Forte is a clinical-strength treatment for excessive sweating (hyperhidrosis). The 60ml roll-ball contains aluminium chloride hexahydrate 20% w/v, which blocks the sweat ducts of the armpits, hands and feet so everyday antiperspirants are no longer being overwhelmed.

What is Anhydrol Forte?

Anhydrol Forte 20% w/v Cutaneous Solution is a pharmacy (P) medicine for hyperhidrosis of the underarms, hands and feet, supplied from our GPhC-registered UK pharmacy. Its roll-ball applicator makes the solution easy to apply exactly where it is needed.

How does it work?

Aluminium chloride reacts with moisture in the sweat duct to form a temporary plug, dramatically reducing the sweat that reaches the skin. With regular use the glands become less active, so most people can cut down to just one or two applications a week once dryness is achieved.

How to use Anhydrol Forte

  • Apply at night to the affected areas, on completely dry skin, and allow to dry.
  • Wash off in the morning.
  • Do not bathe immediately before applying.
  • Use nightly at first, then reduce the frequency as your sweating improves.

Please read the patient information leaflet inside the pack before use.

Avoiding irritation

Stinging or itching usually means the skin was damp, broken or freshly shaved. Apply only to bone-dry, unbroken skin, and do not shave the area within 12 hours before or after applying. If irritation is troublesome, space out the applications.

Important cautions

The solution is highly flammable – keep away from naked flames. Keep it out of the eyes, and away from clothing, jewellery, metal and polished surfaces, as it can damage them. Wash hands after use unless the hands are being treated.

Anhydrol Forte or Driclor?

Both contain aluminium chloride hexahydrate 20% and work the same way. Anhydrol Forte gives you a larger 60ml roll-ball; Driclor is a compact 20ml roll-on. Choose the format you prefer.

Anhydrol Forte FAQs

What is Anhydrol Forte used for?
Anhydrol Forte treats hyperhidrosis – excessive sweating – of the armpits, hands and feet. It contains aluminium chloride hexahydrate 20%, a clinical-strength antiperspirant that blocks the sweat ducts.
How do you use Anhydrol Forte?
Apply the roll-ball to the affected area at night, on completely dry skin, and let it dry. Wash it off in the morning. Use it nightly at first, then reduce how often you apply as the sweating improves – many people maintain dryness with one or two applications a week.
How does Anhydrol Forte work?
The aluminium chloride forms temporary plugs in the sweat ducts so less sweat reaches the surface, and with regular use the sweat glands become less active. That is why the frequency can be reduced over time.
Why must skin be completely dry before applying?
If the skin is damp, the solution reacts with the moisture and is much more likely to sting and irritate – and it works less well. Apply last thing at night to bone-dry skin; do not bathe immediately before use.
Can you shave before using Anhydrol Forte?
Avoid shaving the underarms within 12 hours before or after applying – freshly shaved skin will sting. Shave in the morning after you have washed the solution off instead.
Does Anhydrol Forte sting?
Mild stinging, itching or irritation can happen, particularly at first or if skin is damp or freshly shaved. Applying correctly to dry, unbroken skin at night keeps this to a minimum. If irritation is troublesome, use it less frequently.
Is Anhydrol Forte flammable?
Yes – it has an alcohol base and is highly flammable. Keep it away from naked flames and do not smoke while applying, and let it dry before dressing.
Can children use Anhydrol Forte?
The product is licensed for adults, children and the elderly. For a child with troublesome sweating it is still sensible to check with your pharmacist or doctor first.
Will Anhydrol Forte damage clothes or jewellery?
It can – avoid contact with clothing, jewellery, metals and polished surfaces, and let it dry fully before dressing. Washing it off in the morning before getting dressed protects your clothes.
What is the difference between Anhydrol Forte and Driclor?
They contain the same active, aluminium chloride hexahydrate 20%, and work identically. Anhydrol Forte is a 60ml roll-ball; Driclor is a 20ml roll-on. Pick whichever size and applicator suits you.
