Pregnancy: Category C: A retrospective study found that foetus exposed to Pseudoephedrine during gestation may have increased risk of gastroschisis, a congenital defect of the anterior abdominal wall. However, it is cautioned that underlying maternal illness may have confounded the results of this study. Therefore, Pseudoephedrine should be given only if the potential benefit justified the potential risk to the foetus.
Lactation: Paracetamol is excreted in breast milk in less than 1% of the dose ingested by lactating women. Therefore, maternal ingestion of therapeutic doses does not present a risk to the baby. Only small amounts of Pseudoephedrine are distributed into breast milk and too small to be harmful. Chlorpheniramine may inhibit lactation and should be avoided if possible. Therefore, it is not recommended for lactating women unless the expected benefits outweigh any potential risk.
