Salicylic Acid 20% w/w


How does it work?
It works by softening keratin, a protein that forms part of the skin structure. This helps to loosen the skin cells to allow removal of warts.
Before you use the ointment
When you must not use it:
  • If you have allergy or hypersensitivity to Salicylic Acid or any other ingredient in its preparation.
  • If you are a diabetic.
  • If your peripheral blood circulation is impaired.
  • To treat warts on the face, moles, birthmarks, hairy warts or on genital/anal warts.
  • On children aged less than 2 years 
Pregnant women
Check with your doctor or pharmacist before using your medicine.  
Breast feeding mothers
should be used cautiously in nursing mothers.

Before you start use it
  • Inform your doctor or pharmacist if you are taking or using any other medication at the same time.
  • Inform your doctor or pharmacist if you are allergic to any other drugs.
  • Inform your doctor or pharmacist if you have diabetes, poor blood circulation, or any other health problems.
  • Inform your doctor or pharmacist if you are or plan to get pregnant, or are breastfeeding.
  • Consult your doctor before using this medication on children aged 2-12 years.
  • Consult your doctor before using this medication on elderly.
  • Follow your doctor’s instruction carefully. They may differ from the general instructions in the medication leaflet.
  • Before using the ointment, moisten or soak the wart in warm water for about 5 minutes to help loosen and soften the skin. Dry thoroughly. Use an emery board or pumice stone to carefully remove the top dead layers of skin on the affected area (avoid sharing this emery board/pumis stone with others). This dead skin removal is to help the medication penetrate the skin more easily. Protect surrounding healthy skin (eg. with white soft paraffin or specially designed plaster).
Taking other medicines
Please tell your doctor or pharmacist if you are taking/using or have recently taken/use any other medicines or preparations such as:  
  • Any other medicated topical agents, e.g. benzoyl peroxide, topical retinoids, salicylate and hydroquinone.
  • Abrasive soap and cleanser.
  • Cosmetics or soap that dry the skin or are designed to peel/ exfoliate.
  • Protein bound drugs.
  • Alcohol containing preparations.
How to use the ointment.
How much to use 
Apply a thin layer of the ointment to cover the entire warts. Be careful to apply it only to the affected area and not the surrounding skin.

When to use it
  • Treatment should start as early as possible after the start of an infection.
  • Subsequently, it may then be possible to maintain improvement by less frequent application. 
  • The treatment may be used once or twice daily (in the morning and at night) or as directed by your doctor or pharmacist.
How long to use it
  • You need to apply the medication as instructed until the wart clears up, for up to 12 weeks or as directed by your doctor or pharmacist.
  • If the wart persists after 12 weeks, consult your doctor.
If you forget to take it
  • Apply it as soon as you remember. 
  • If it is almost time for your next dose, wait until then to apply the ointment.  
  • Do not double the dose.
If your use too much
If you accidentally used too much of the ointment, consult your doctor immediately. 

While you are using it

  • Do not use large amounts, or apply this medication more often. Do not use Salicylic Acid ointment over large skin areas for long period (more than 12 weeks) or more than as directed by your doctor.

Things to be careful of
  • Be careful to apply it only to the affected area and not the surrounding skin.
