Information for Patients
Read all of this leaflet carefully because it contains important information for you.
This medicine is available without prescription. However, you still need to use Occlusal carefully to get the best
results from it.
• Keep this leaflet. You may need to read it again.
• Ask your pharmacist if you need more information or advice.
• You must contact a doctor, pharmacist or nurse if your symptoms worsen or do not improve.
• If any of the side effects gets serious, or if you notice any side effect not listed in this leaflet, please tell your
doctor, pharmacist or nurse.
The information in this leaflet has been divided into the following sections:

2. Check before you use Occlusal

4. Possible side effects
5. How to store Occlusal
6. Further information

Gently remove any loose
tissue from the wart
surface by rubbing with a
brush, emery board, pumice
or abrasive sponge. Be
careful not to damage the
healthy skin.


Use the applicator brush
supplied in the cap to apply
Occlusal to the wart. Do not
get any on the surrounding
healthy skin. Allow Occlusal
to dry completely and then
apply a second coat. You do
not need to cover the wart
with a plaster or bandage.

You should notice an improvement within 1-2 weeks but for maximum effect, continue treatment for 4-6 weeks.
Do not allow the solution to drip onto the neck of the bottle or you may find it difficult to open the bottle next time.
What to do if you use more Occlusal than you should
If you accidentally swallow Occlusal, use too much of it or use it for long periods of time, the body could absorb
too much salicylic acid. This could cause ringing in the ears, feeling or being sick. If this occurs, or you notice
any other symptoms, stop using Occlusal and consult your doctor.
If you forget to use Occlusal
If you forget to use Occlusal on any occasion, do not worry, just continue to use daily as before.
If you have any further questions on the use of this product, ask your doctor, nurse or pharmacist.
4. Possible side effects
Do not worry. Like all medicines, Occlusal can cause side effects, although not everyone gets them.

1. What Occlusal is and what it is used for
Occlusal is used to treat and remove raised warts (usually found on the hands, elbows or knees) and verrucas
(warts on the feet). Occlusal is a special solution which can be easily applied to the wart, dries quickly, needs no
plasters and if used properly should cause minimal irritation.

If any of the following symptoms occur you should stop using Occlusal and contact your doctor or pharmacist:
• ringing in the ears
• feeling or being sick.

Warts, or verrucas as they are often called, are found most commonly on the hands, feet and knees. They are
commonest amongst children of school age.

Other side effects include:
• redness, rash or itching affecting the normal skin around the wart. If this occurs, stop using Occlusal for a
few days until the irritation goes away. When you re-start treatment, be careful to apply the solution only to
the wart itself.

Warts are caused by a virus which gets into the upper layers of the skin. The body then reacts to the virus,
which leads to the formation of the wart or verruca. Warts are most frequently transmitted by contact, e.g.
swimming pools and communal changing rooms are often associated with infection. Warts can occur singly or in
groups and can be transferred from one part of the body to another, e.g. from one foot to the other.
Occlusal contains a high concentration of salicylic acid which when used regularly removes the dead cells from
the outer layer of the skin and steadily reduces the size of the wart.
2. Check before you use Occlusal
Do not use Occlusal:
• if you are allergic (hypersensitive) to salicylic acid (aspirin) or any of the other ingredients of Occlusal (see
section 6 Further information)
• if you have diabetes
• if you have poor blood circulation
• if the wart or skin surrounding it is inflamed or broken
• on moles, birthmarks, unusual warts with hairgrowth
• on your face
• on warts in the anal or genital region.
Take special care with Occlusal
Occlusal is flammable – keep it away from flames and fire.

Keep out of the reach and sight of children.
Do not use Occlusal after the expiry date which is stated on the carton and bottle. The expiry date refers to the
last day of that month after EXP.

Do not use Occlusal if you notice a change in the colour of the solution.

Do not use on broken or damaged skin such as cuts or grazes.
Try not to get Occlusal on the normal skin around the wart. You should apply Occlusal to the centre of the wart
therefore avoiding the surrounding healthy skin.
Do not allow Occlusal to come into contact with mucous membranes (e.g. your mouth, nose and other body
openings) or your eyes.
If Occlusal gets into any of these areas, flush immediately with water for 15 minutes.
Using other medicines
When used according to the instructions, Occlusal is not known to interfere with any other medicines. However
you should not use any other treatments on your warts or verrucas at the same time as using Occlusal.
