If a pregnant woman needs neuroleptic treatment during pregnancy, the fetus is sensitive to the drug during the first trimester and treatment during the second trimester may cause miscarriage. It is generally recommended that neuroleptic treatment be administered during the fourth to sixth months of pregnancy. Special attention should be paid to the drugs used in neuroleptic treatment. Instead of using CP or FC, which are often used, softer drugs such as wood distillate, calcium hydroxide, chlorhexidine, etc. can be used. These drugs can kill bacteria and disinfect the medulla relatively gently. After the normal nerve killing treatment, the filling treatment is performed during pregnancy.
