Pregnancy: There is insufficient clinical experience with gabapentin in pregnancy to confirm its safety in this patient population. Since gabapentin is frequently prescribed with other anticonvulsants, a clear association between maternal gabapentin use and fetal adverse effects cannot be determined. Due to lack of adequate, well-controlled studies, hence it is recommended that gabapentin should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus.
Lactation: Gabapentin is excreted in human milk. Because the effect on the nursing infant is unknown, caution should be exercised when gabapentin is administered to a nursing mother. Gabapentin should be used in nursing mothers only if the benefits clearly outweigh the risks.
