7. The method according to claim 5 , wherein the avermectin, milbemycin, or salt thereof, is present in an amount from 0.001% to 10% by weight based on the total weight of the composition.
8. The method according to claim 5 , wherein the avermectin, milbemycin, or salt thereof, is present in an amount from 0.01% to 5% by weight of the composition.
9. The method according to claim 1 , wherein the complication is vaginal intraepithelial neoplasias and/or cervical intraepithelial neoplasias.
10. The method according to claim 1 , wherein the composition further comprises at least one other therapeutic agent selected from the group consisting of an antibiotic, an antibacterial agent, an antiviral agent, an antiparasitic agent, an antifungal agent, an anesthetic, an analgesic, a keratolytic, a podophyllotoxin, and an immunostimulating product of the imiquimod type.
11. The method according to claim 1 , wherein the composition is administered once a day.
12. The method according to claim 1 , wherein the treatment is from 1 week to 6 months.
13. The method according to claim 1 , wherein the treatment is from 2 weeks to 4 months.
