<p><strong>Pregnancy</strong>: There are no data from the use of Pirfenidone in pregnant women. In animals placental transfer of pirfenidone and/or its metabolites occurs with the potential for accumulation of pirfenidone and/or its metabolites in amniotic fluid. At high doses (1000 mg/kg/day) rats exhibited prolongation of gestation and reduction in fetal viability. As a precautionary measure, it is preferable to avoid the use of Pirfenidone during pregnancy.<br />
<br />
<strong>Lactation</strong>: It is unknown whether pirfenidone or its metabolites are excreted in human milk. Available pharmacokinetic data in animals have shown excretion of pirfenidone and/or its metabolites in milk with the potential for accumulation of pirfenidone and/or its metabolites in milk. A risk to the suckling child cannot be excluded. A decision must be made whether to discontinue breast-feeding or to discontinue from Pirfenidone therapy, taking into account the benefit of breast-feeding for the child and the benefit of Pirfenidone therapy for the mother.<br />
<br />
<strong>Fertility</strong>: No adverse effects on fertility were observed in preclinical studies. Effects on ability to drive and use machines: No studies on the effects of the ability to drive and use machines have been performed. Pirfenidone may cause dizziness and fatigue, which could influence the ability to drive or use machines.</p>
