Podofilox comes as a liquid to treat warts around the genitals and as gel to treat warts around the anus or the genitals. Don’t confuse it with podophyllin, also used for genital warts, but more harmful if not used correctly. Podofilox is safer to use.
The health worker can apply it for the first time in the clinic to show how to do it. The person may need help using podofilox if the warts are hard to see or to reach. Apply the liquid with a cotton swab or the gel with a finger. Wash hands after use. Wait until it dries before putting clothes on.
Podofilox can irritate skin, causing it to thin, break, and bleed.
Do not use this if you are pregnant or breastfeeding.
If severe skin irritation occurs, do not use it again.
