How It Works
The active ingredient in Avoca Wart and Verruca Treatment Set is silver nitrate 95% w/w, delivered via a caustic pencil applicator. Silver nitrate is a well-established caustic agent that has been used in medicine for many years. When applied directly to a wart or verruca, it causes a localised chemical reaction that destroys the abnormal skin cells making up the lesion. The treated tissue turns black or dark brown, which is a normal and expected response, indicating that the silver nitrate is working. Over the following days, the dead tissue gradually separates from the healthy surrounding skin, allowing the wart or verruca to be removed. The pen-style applicator provides precise, targeted application, minimising contact with the healthy skin surrounding the affected area.

Directions for Use
Always read the patient information leaflet supplied with this product before use. The following is a general guide:
- Soak the wart or verruca in warm water for approximately two to three minutes to soften the skin.
- Carefully dry the area thoroughly with a clean tissue or towel.
- Remove the cap from the applicator pencil and moisten the tip very slightly with water.
- Apply the tip of the pencil gently to the surface of the wart or verruca only. Avoid contact with surrounding healthy skin.
- Allow the treated area to dry for one to two minutes before covering with the adhesive dressing provided.
- Repeat the application once daily for up to three consecutive days.
- After the course of treatment, allow the treated tissue to separate naturally over the following days. Do not forcibly remove it.
- If the wart or verruca has not cleared after three days, a second course of treatment may be applied after a gap of 24 hours. Do not exceed two courses without seeking medical advice.
- Wash hands thoroughly after handling the applicator pencil.
- For children under six years of age, consult your doctor or your PillSorted pharmacist before use.

Active Ingredients
The sole active ingredient in Avoca Wart and Verruca Treatment Set is:
- Silver nitrate 95% w/w – presented as a caustic pencil applicator. Silver nitrate is a potent caustic substance that chemically destroys wart and verruca tissue upon direct contact. At this concentration, it acts rapidly and effectively to break down the hardened, virus-infected cells associated with common warts (caused by the human papillomavirus, HPV) and verrucas (plantar warts). The 95% w/w concentration is specifically formulated to be sufficiently strong for effective removal whilst being contained within a controlled applicator to assist with precise use.
This product contains no other active pharmaceutical ingredients. For a full list of excipients and other components, please refer to the patient information leaflet enclosed within the packaging.

Possible Side Effects
Like all medicines, Avoca Wart and Verruca Treatment Set can cause side effects, although not everybody will experience them. The following effects are associated with the use of silver nitrate:
- Very common (may affect more than 1 in 10 people): Staining of the skin, nails, and surrounding tissue black or dark brown. This is a normal and expected consequence of silver nitrate use and will gradually fade over time.
- Common: Mild localised burning, stinging, or irritation at the site of application.
- Uncommon: Redness, swelling, or inflammation of the surrounding skin, particularly if the product comes into contact with healthy skin.
- Rare: More significant skin irritation, blistering, or chemical burns if the product is applied to broken, sensitive, or healthy skin, or if it is used more frequently than directed.
- Very rare: Allergic reactions, including rash, itching, or hypersensitivity. If you suspect an allergic reaction, stop use immediately and seek medical advice.
If you experience any side effect that is not listed here, or if a listed side effect becomes severe, speak to your doctor or your PillSorted pharmacist promptly.

Interactions
Avoca Wart and Verruca Treatment Set is applied topically and is not known to cause significant systemic drug interactions when used as directed. However, the following points should be considered:
- Do not use this product at the same time as other topical wart or verruca treatments (such as salicylic acid preparations) on the same lesion, unless specifically advised to do so by your doctor or PillSorted pharmacist. Combining caustic or keratolytic agents may increase the risk of skin damage and irritation.
- Avoid applying any other topical products, creams, or ointments directly to the treated area until the skin has fully healed, as this may interfere with the action of the silver nitrate or increase the risk of adverse skin reactions.
- If you are using any prescription topical treatments in the same area, inform your doctor or PillSorted pharmacist before using this product.
If you are taking any oral or systemic medications, there is no known interaction with topically applied silver nitrate at the concentrations present in this product. Nevertheless, always inform your PillSorted pharmacist of all medicines you are currently using.
⸻
Pregnancy and Breastfeeding
The safety of silver nitrate 95% w/w applied topically during pregnancy and breastfeeding has not been fully established in clinical studies. Although the risk of significant systemic absorption from a small, localised topical application is considered to be very low, caution is advised.
- Pregnancy: If you are pregnant or think you may be pregnant, seek advice from your doctor or midwife before using this product. Do not use on areas of skin that may allow significant absorption.
- Breastfeeding: If you are breastfeeding, consult your doctor or PillSorted pharmacist before use. Ensure that the treated area is kept well away from the infant, particularly if the wart or verruca is located on or near the breast.
- Trying to conceive: If you are trying to conceive, it is advisable to seek medical advice before using any caustic topical treatment.
⸻
Alcohol
There are no known interactions between alcohol and the topical use of silver nitrate 95% w/w as contained in Avoca Wart and Verruca Treatment Set. This product is applied directly to the skin and is not ingested or absorbed systemically in clinically significant amounts under normal conditions of use. Alcohol consumption is therefore not expected to affect the safety or efficacy of this treatment. If you have any concerns, please speak to your PillSorted pharmacist.
