==Overview==
Genital warts may disappear without treatment, but sometimes eventually develop a fleshy, small raised growth. There is no way to predict whether they will grow or disappear.
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.

*The primary reason for treating genital warts is the amelioration of symptoms (including relieving cosmetic concerns) and ultimately, removal of the warts. In most patients, treatment can induce wart-free periods.


*If left untreated, visible genital warts can resolve on their own, remain unchanged, or increase in size or number. Available therapies for genital warts likely reduce, but probably do not eradicate, HPV infectivity.
:::* 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.


*Whether the reduction in HPV viral DNA resulting from treatment reduces future transmission remains unclear. No evidence indicates that the presence of genital warts or their treatment is associated with the development of cervical cancer.
:::* 3.2 '''Pregnancy'''
::::* [[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).


*Factors that influence selection of treatment include wart size, wart number, anatomic site of the wart, wart morphology, patient preference, cost of treatment, convenience, adverse effects, and provider experience.
:::* 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


*The treatment modality should be changed if a patient has not improved substantially after a complete course of treatment or if side effects are severe. Most genital warts respond within 3 months of therapy.
:::* 3.4 '''High-grade squamous intraepithelial lesions'''
{| style="background: #FFFFFF;"
::::* 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.

*Podophyllin and podofilox should not be used during [[pregnancy]], as they are absorbed by the skin and may cause [[birth defect]]s in the [[fetus]]. 5-fluorouracil cream should not be used while trying to become pregnant or if there is a possibility of pregnancy.
 
Some doctors inject the antiviral drug [[interferon]]-alpha directly into the warts, to treat warts that have returned after removal by traditional means. The drug is expensive, and does not reduce the rate that the warts return.
* In general, warts located on moist surfaces or in intertriginous areas respond best to topical treatment.
 
*Patients should be warned that persistent hypopigmentation or hyperpigmentation occurs commonly with ablative modalities and has also been described with immune modulating therapies (imiquimod).
