There are no adequate data from the use of Levetiracetam in pregnant women. Studies in animals have shown reproductive toxicity.
The potential risk for humans is unknown. Levetiracetam should not be used during pregnancy unless clearly necessary.
As with other antiepileptic drugs, physiological changes during pregnancy may affect Levetiracetam concentration. There have been reports of decreased Levetiracetam concentration during pregnancy. Discontinuation of antiepileptic treatments may result in exacerbation of the disease which could be harmful to the mother and the foetus.
Levetiracetam is excreted in human breast milk. Therefore, breast-feeding is not recommended.
