<p><strong>Pregnancy Category</strong>: Interferon Alfa-2a should be administered only if the benefit to the woman justifies the potential risk to the foetus. Although animal tests do not indicate that Roferon-A is a teratogen, harm to the foetus from use during pregnancy cannot be excluded. When doses greatly in excess of the recommended clinical dose were administered to pregnant rhesus monkeys in the early to mid foetal period, an abortifacient effect was observed.<br />

<strong>Nursing mothers</strong>: It is not known whether Interferon Alfa-2a is secreted in human milk. A decision must be taken whether to suspend breast-feeding or to discontinue the medicine, taking into account the importance of the medicine to the mother.</p>
