We do not discontinue the antipsychotic even before delivery (Seifertová et al., 2007).In maintenance therapy, it is better to administer a minimal dose of an antipsychotic continuously than to administer high doses intermittently to decompensate the condition (Seifertová et al., 2007). | Beginning of 2nd month, (1st trimester), 50 mg, 2 weeks | 1 | Healthy newborn |

If ibuprofen is used by a woman trying to become pregnant or during the 1st and 2nd trimesters of pregnancy, she should take low doses, and the treatment should be as short as possible (ŠÚKL, 2018a). | Beginning of 2nd month (1st trimester), 400 mg, 8 weeks | 1 | Healthy newborn |
