Dacrynic cream should not be used by pregnant women during pregnancy. Dacrynic cream is an anti-mycotic drug and its long-term use may cause fetal malformation and fetal growth and development restriction, so it is not recommended for pregnant women. If pregnant women suffer from mycosis fungoides, they can be given gynecological cleansing lotion to cleanse the vulva and nifurtimycin soft capsule to plug the vagina. Dacronin cream is a compound preparation of zinc chloride, talcum powder and miconazole, which has the effect of drying the skin, dissipating heat and relieving itching, reducing local irritation and friction, mainly for mycosis fungoides, but also for tinea pedis. However, Dacrynic cream has side effects of teratogenicity and affecting fetal growth, so try not to use Dacrynic cream during pregnancy.
