Pregnancy
There are no adequate and well-controlled studies in pregnant women
Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed
Animal studies
Reproduction studies in pregnant rats and rabbits at doses up to 100 mg/kg and 40 mg/kg, respectively (20 and 17 times the maximum recommended human dose [MRHD] on an mg/m2 basis, respectively), have revealed no evidence of teratogenic effects
However, in rats, there was an increase in postimplantation losses in dams treated with mirtazapine
Lactation
May be excreted in breast milk; caution advised
Interactions

Increased plasma levels with potent CYP3A4 inhibitors (e.g. HIV-protease inhibitors, azole antifungals including ketoconazole, erythromycin, nefazodone). Reduced plasma levels with carbamazepine and other inducers of CYP3A4. Increased bioavailability with cimetidine.
