Podophyllin resin and podofilox lotion or gel remove genital warts by stopping cell growth.
A doctor applies podophyllin resin to the warts. He or she also may use petroleum jelly, such as Vaseline, to protect normal tissue near the warts from irritation. You wash the resin off in 1 to 4 hours to reduce side effects.1 Your doctor usually applies the resin once a week for at least 6 weeks or until warts disappear.
You can apply podofilox in lotion or gel at home. The usual schedule is twice a day for 3 days, followed by 4 days without any lotion. You repeat this schedule for up to 4 weeks.1

Genital warts may go away on their own. Also, treating genital warts does not cure infection with human papillomavirus (HPV), the virus that causes genital warts. The virus may remain in the body in an inactive state after warts are removed. A person treated for genital warts may still be able to spread the infection. Condoms may help reduce the risk of HPV infection.
The benefits and effectiveness of each type of treatment need to be compared with the side effects and cost. Discuss this with your doctor.
