| No treatment in common use is 100% effective. The most comprehensive medical review found that no treatment method was more than 73% effective and using a [[placebo]] had a 27% average success rate. The [[American Family Physician]] recommends:{{ref|afp2005}}

| [[Podiatrist]]s and [[Dermatology|dermatologists]] are considered specialists in the treatment of plantar warts, though most warts are treated by [[primary care physician]]s.
| |
|
| |
| ===Vaccination===
| |
| Although immunization is available for the HPV and strains causing [[cervical cancer]] and [[venereal warts]], there is currently no vaccination treatment for plantar warts.
| |
|
| |
| ===Pharmacologic Rx===
| |
| ; [[Keratolytic|Keratolytic Chemicals]]: The [[treatment of warts by keratolysis]] involves the peeling away of dead surface skin cells with [[trichloroacetic acid]] or [[salicylic acid]].
| |
| ; [[Immunotherapy]]: Intralesional injection of antigens ([[mumps]], candida or trichophytin antigens USP) is a new wart treatment which may trigger a host immune response to the wart virus, resulting in wart resolution. Distant, non-injected warts may also disappear.
| |
| ; [[Chemotherapy]]: Topical application of dilute [[glutaraldehyde]] (a virucidal chemical, used for cold sterilization of surgical instruments) is an older effective wart treatment. More modern chemotherapy agents, like 5-fluoro-uracil, are also effective topically or injected intralesionally. [[Retinoid]]s, systemically (eg. [[isotretinoin]]) or topically ([[tretinoin]] cream) may be effective.

| |
| :As warts are contagious, precautions should be taken to avoid spreading.
| |
|
| |
| ===Surgical===
| |
| * Liquid nitrogen : [[Cryosurgery]] with [[liquid nitrogen]]. A common treatment that works by producing a blister under the wart. It is painful but usually nonscarring.
| |
| * Electrodesiccation and surgical excision produce scarring. If the wart recurs, the patient has a permanent scar along with the wart.
| |
| * Lasers may be effective, especially the 585nm pulsed dye laser which the most effective treatment of all, and does not leave scars, but is generally a last resort treatment as it is expensive and painful, and multiple laser treatments are required (generally 4-6 treatments repeated once a month until the wart disappears).
| |
|
| |
| ===Other===
| |
| * X-ray is an old method that is seldom recommended due to the long term adverse side effects of irradiation.
| |
| * [[Duct tape occlusion therapy]]: The wart is kept covered with duct tape for six days, then soaked and debrided with a pumice stone. The process is repeated for 6 to 8 weeks.{{ref|ducttape}}
| |
| * [[Watchful waiting]] may be appropriate since many warts will eventually resolve due to the patient's own immune system. In many cases, the body will become naturally immune to the wart and verrucæ will turn black and effectively fall off, although it can be two years before this takes place

Diagnosis
Relative effectiveness of treatments
A 2006 study assessed the effects of different local treatments for cutaneous, non-genital warts in healthy people. The study reviewed 60 randomized clinical trials dating up to March 2005. The main findings were:
- overall there is a lack of evidence (many trials were excluded because of poor methodology and reporting).
- the average cure rate using a placebo was 27% after an average period of 15 weeks.
- the best treatments are those containing salicylic acid. They are clearly better than placebo.
- there is surprisingly little evidence for the absolute efficacy of cryotherapy.
- two trials comparing salicylic acid and cryotherapy showed no significant difference in efficacy.
- one trial comparing salicylic acid and duct tape occlusion therapy showed no significant difference in efficacy.
- evidence for the efficacy of the remaining treatments was limited.
Complications
Prevention
- Avoid walking barefoot in public areas such as showers, communal changing rooms. (Covering with an adhesive bandage is not a safe method as it will not last for long at all, especially while showering or swimming)
- Change shoes and socks daily.
- Avoid sharing shoes and socks.
- Avoid direct contact with warts on other parts of body.
- Avoid direct contact with warts on other persons.
