Warts during pregnancy can be treated by applying 50% trichloroacetic acid until the 36th week of pregnancy. TCA is a corrosive astringent that achieves its therapeutic purpose by precipitating vascular cells. Because it is not absorbed by the organism, it rarely produces local reactions and has no adverse effect on the fetus. Weekly medication until healing is required under medical supervision. If the lesions grow more rapidly during pregnancy, liquid nitrogen, cryotherapy, or surgery can also be considered, and pregnant women should be fully informed of the risks they face with treatment. Treatment with onychomycetin ointment only during pregnancy will not stop a pregnancy because of warts, if there is no specific reason for it. In cases of near-full-term or full-term pregnancies, medication is generally not used to avoid affecting the fetus.
