Treatment Options
Most common warts respond to over-the-counter measures such as salicylic acid or medicated plasters when used consistently. Some warts are treated with cryotherapy (cold therapy) which may be provided in clinic settings; repeated sessions are often required. For painful, rapidly spreading, or unusual lesions a professional assessment is recommended. Good hygiene helps prevent spread: avoid sharing towels, keep feet dry, and cover warts when swimming. If uncertain about treatment choice, ask the pharmacist for product selection, safe application instructions, and expected timelines for improvement.

Types and symptoms
Recognising Different Warts
Warts are small skin growths caused by certain strains of the human papillomavirus (HPV). Common types include common warts (hands), plantar warts (feet), flat warts (face or legs) and filiform warts (neck or near the mouth). Plantar warts can be painful due to pressure when walking. Warts are usually rough and may have tiny black dots (clotted blood vessels). They can spread by direct contact or via contaminated surfaces. Early treatment can reduce spread and discomfort; for persistent, painful, or rapidly growing warts seek a professional review.
Frequently Asked Questions
Answers to common wart concerns.
What causes warts?
Warts are caused by the human papillomavirus (HPV). The virus infects the top layer of skin and often enters via small cuts or abrasions. Different HPV strains cause different wart types. Warts are common in children and young adults but can affect any age.
Are warts contagious?
Yes. Warts can spread through direct skin-to-skin contact or indirectly via shared surfaces such as towels or floors. Avoid picking or scratching warts, cover them if swimming, and maintain good hand and foot hygiene to reduce transmission.
How long until a wart disappears?
It varies. Some warts resolve within months without treatment while others persist for years. Treatment can accelerate removal but may need several weeks of consistent application or multiple clinical sessions to be effective.
Is it safe to treat warts at home?
Many over-the-counter options are safe when used correctly, such as salicylic acid. Avoid using strong chemicals on sensitive areas like the face or genitals. Always follow product instructions and consult a pharmacist for dosing or age restrictions.
When should I see a healthcare professional?
See a healthcare professional if warts are painful, bleeding, changing in appearance, multiply rapidly, are on the face or genitals, or if you have diabetes or a weakened immune system. Persistent warts that don’t respond to treatment also need review.
Quick Key Points
Quick practical points: most warts are harmless and can be managed with over-the-counter products when used consistently. Salicylic acid treatments require regular application and can take weeks to show results. Avoid picking warts to reduce spread; cover them when swimming and dry feet thoroughly after bathing. Children often develop warts but may respond well to simple treatments. If warts are painful, spreading, or resistant to treatment, arrange a professional assessment for other options such as clinic cryotherapy, topical prescription treatments, or referral to a specialist.

When pharmacy care isn't enough
Professional Treatments and Referrals
When over-the-counter measures fail, professional options include stronger cryotherapy, prescription topical treatments, or minor procedures performed by specialists. Cryotherapy freezes the wart tissue and may require repeat sessions; it can be painful and cause temporary blistering. Referral to a podiatrist is common for stubborn plantar warts affecting mobility. Some treatments are not suitable for people with certain medical conditions, and wart removal on the face or genitals should only be done by trained clinicians. Aftercare includes gentle cleaning, avoiding irritation, and monitoring for infection or unusual changes.

When to Get Specialist Help
Warts that are painful, rapidly increasing in number, changing in appearance, or located on the face or genitals should be assessed promptly. Also seek help if you have diabetes, circulatory problems, or a weakened immune system before attempting self-treatment. A clinician can advise safe removal options and check for other skin conditions that may mimic warts.
Safe home care and prevention tips
Home Care and Prevention
Effective home management includes selecting the right product for the wart type and following application instructions carefully. Salicylic acid needs regular application with skin trimming where appropriate; medicated plasters can simplify dosing. Keep treated skin protected, avoid contact with healthy skin, and wash hands after handling. If you notice irritation, significant pain, or no improvement after several weeks, stop treatment and seek professional advice. Pharmacists can recommend suitable preparations, advise on age restrictions, and suggest next steps such as clinic-based cryotherapy or specialist referral.
