when someone has hpv or genital warts, do they have to take medication to supress having out-breaks?
I am not aware of any medications that are effective in suppressing outbreaks of genital warts. Warts should be treated when they are present. Aggressively treating the warts may reduce the chances of warts coming back, but it is not guaranteed. Treatment can also reduce the risk of transmitting the HPV to your sexual partners. You should only have a doctor treat the warts; don't try to do it yourself.
It is especially important for people with warts in the rectum or vagina to have them treated. It is possible that warts left untreated in those areas, especially in HIV positive people, may lead to certain types of cancers. People with compromised immune systems are more prone to repeated and more severe outbreaks than those with normal immune systems.
