==Overview==
Some warts will disappear without treatment, although it can sometimes take a couple of years. Treated or not, warts that go away often reappear. All warts can spread from one part of your own body to another. Unsightly or painful warts can be treated. Warts around and under your nails are much more difficult to cure than warts in other places.
Medical therapies for human papillomavirus infection include either [[imiquimod]], [[sinecatechins]], or [[podofilox]].<ref name=CDC>{{Cite journal| issn = 1545-8601| volume = 64| issue = RR-03| pages = 1–137| last1 = Workowski| first1 = Kimberly A.| last2 = Bolan| first2 = Gail A.| title = Sexually transmitted diseases treatment guidelines, 2015| journal = MMWR.

One review of 52 clinical trials of various cutaneous wart treatments concluded that topical treatments containing salicylic acid were the best supported, with an average cure rate of 75% observed with salicylic acid compared with 48% for placebo in six placebo-controlled trials including a total of 376 participants.<ref name="Cochrane">[http://www.mrw.interscience.wiley.com/cochrane/clsysrev/articles/rel0001/CD001781/pdf_fs.html Gibbs S, Harvey I, Sterling JC, Stark R. (2003) Local treatments for cutaneous warts. ''Cochrane Database of Systematic Reviews'' Issue 3]</ref> The reviewers also concluded that there was little evidence of a significant benefit of cryotherapy over [[placebo]] or no treatment.<ref name="Cochrane"/>
:::* 3.1 '''Management of sex partners'''
::::* Persons should inform current partner(s) about having genital warts because the types of HPV that cause warts can be passed on to partners. Partners should receive counseling messages that partners might already have HPV despite no visible signs of warts, so HPV testing of sex partners of persons with genital warts is not recommended.


====Over-the-counter====
:::* 3.2 '''Pregnancy'''
There are several [[over-the-counter drug|over-the-counter]] options. The most common ones involve [[salicylic acid]].  These products are readily available at [[drugstore]]s and [[supermarket]]s. There are typically two types of products: adhesive pads treated with salicylic acid or a bottle of concentrated salicylic acid. Removing a wart with salicylic acid requires a strict regimen of cleaning the area, applying the acid, and removing the dead skin with a [[pumice]] stone or [[emery board]]. It may take up to 12 weeks to remove a wart.
::::* [[Podofilox]] (podophyllotoxin), [[Podophyllin]], and [[Sinecatechins]] should not be used during pregnancy. Imiquimod appears to pose low risk but should be avoided until more data are available.
::::* Cesarean delivery is indicated for women with anogenital warts if the pelvic outlet is obstructed or if vaginal delivery would result in excessive bleeding.  
::::* Pregnant women with anogenital warts should be counseled concerning the low risk for warts on the larynx of their infants or children (recurrent respiratory papillomatosis).


Another over-the-counter product that can aid in wart removal is [[silver nitrate]] in the form of a [[caustic pencil]], which is also available at drug stores. This method generally takes three to six daily treatments to be effective. The instructions must be followed to minimize staining of skin and clothing.
:::* 3.3 '''HIV infection'''
::::* Data do not support altered approaches to treatment for persons with HIV infection.
::::* Squamous cell carcinomas arising in or resembling anogenital warts might occur more frequently among immunosuppressed persons, therefore requiring biopsy for confirmation of diagnosis for suspicious cases


Over-the-counter cryosurgery kits are also available, however they can often cost three times as much as the previously named products.
:::* 3.4 '''High-grade squamous intraepithelial lesions'''
::::* Biopsy of an atypical wart might reveal HSIL or cancer of the anogenital tract. In this instance, referral to a specialist for treatment is recommended.


Like prescription treatments, over-the-counter treatments usually require multiple applications and are only necessary if the warts are problematic. Additionally, these treatments are capable of destroying healthy skin as well as warts, so caution must be exercised by those attempting them without medical supervision.
===Follow-up===
* Most anogenital warts respond within 3 months of therapy.
*Factors that might affect response to therapy include immunosuppression and treatment compliance.
*In general, warts located on moist surfaces or in intertriginous areas respond best to topical treatment.
*A new treatment modality should be selected when no substantial improvement is observed after a complete course of treatment or in the event of severe side effects; treatment response and therapy-associated side effects should be evaluated throughout the course of therapy.

* [[Duct tape occlusion therapy]] involves placing a piece of [[duct tape]] (or medical tape) over the affected area for a week at a time.  The procedure is otherwise identical to that of using salicylic acid adhesive pads.
* One study by ''Focht et al.'' found that the duct tape method was 85% effective, compared to a 60% success rate in the study's cryotherapy group.<ref>[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=12361440&query_hl=3&itool=pubmed_docsum Focht DR III, Spicer C, Fairchok MP (2002) The efficacy of duct tape vs cryotherapy in the treatment of verruca vulgaris (the common wart).

* Another study by ''Wenner and coworkers'', however, found no statistically significant effect in a double-blind, randomized and controlled clinical trial in 90 adults when duct tape was compared to mole skin.<ref>[http://www.ncbi.nlm.nih.gov/sites/entrez?Db=pubmed&Cmd=ShowDetailView&TermToSearch=17372095&ordinalpos=2&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum Wenner et al. Duct tape for the treatment of common warts in adults: a double-blind randomized controlled trial. Arch Dermatol. 2007 Mar;143(3):309-13.]</ref>
* There was no statistically significant difference for resolution of the target wart between patients treated with moleskin versus patients treated with duct tape. Eight of 39 patients [21%] in the treatment group vs 9 of 41 patients in the control group [22%] had complete resolution of the target wart. Fewer of the patients achieving resolution of their wart in the moleskin group had recurrence of their wart. Of the patients who had complete resolution, 6 (75%) in the treatment group and 3 (33%) in the control group had recurrence of the target wart by the sixth month.  "Whether or not the standard type of duct tape is effective is up in the air," said co-author Dr. Rachel Wenner of the University of Minnesota, who started the new study as a medical student. "Theoretically, the rubber adhesive could somehow stimulate the immune system or irritate the skin in a different manner."<ref>[http://newsmax.com/archives/articles/2007/3/20/161113.shtml Study Casts Doubt on Duct Tape Wart Cure]. [[March 21]], [[2007]].</ref>
* Fig latex, the sap from a fig tree, is also a common treatment for warts. Studies on cows comparing treatment with fig latex to salicylic acid showed that fig latex worked equally well.
* An Iranian study compared fig latex treatment on humans to cryotherapy and found the fig latex to be only slightly less effective, but with the benefit of fewer side effects.
* Tempra paint serves as a successful treatment as well. Dabbed onto the surface of a wart and allowed to dry completely, it will noticably reduce the size of the wart over a period of days. Removal of the wart can take a week or more. Children who frequently fingerpaint with Tempra show it to be successful as a remedy. Caution and close observation is advised however, as infection and permanent scarring can occur.
* Other household remedies include the application of common household items, such as a bruised garlic (held in place with a bandage or duct tape), banana skin, vinegar <ref>{{cite web|url=http://www.cidervinegar.org/2007/07/apple-cider-vinegar-for-warts_02.html|title=Apple Cider Vinegar for Warts}}</ref>, hot water and washing liquid, aerosol sprays or compressed air, [[Thuja occidentalis]], [[tea tree oil]] and other natural oils, unskinned potatoes, potato or cauliflower or tomato juice, salt, or [[vegemite]] to the affected area.
* [[Milkweed]], [[dandelion]], and [[poison ivy]] sap have also been used. Accounts vary in regards to how long these remedies must be applied with each session and how long they take to work.


Without controlled studies for most household remedies, it is difficult to know whether the warts disappear because the remedies work, or if they disappear due to the individual's own immune system response to the virus (possibly augmented by a [[placebo effect]]).  The success of [[hypnosis]] in curing warts<ref>[http://www.internethealthlibrary.com/Health-problems/Warts%20-%20researchAltTherapies.htm Alternative & Complementary Therapies: Hypnotherapy & Warts]</ref> at least suggests that the condition may be cured by belief in a remedy, the placebo effect or other psychological means.

Some household remedies are potentially dangerous.  These include attempts to cut or burn away the warts.  [[Incense]] is sometimes used in Asian countries to burn warts.  These methods are very [[Pain and nociception|painful]], and can lead to [[infection]] and/or permanent [[scar]]ring.
