Co-Phenylcaine Forte Spray should not be used in pregnancy.
Co-Phenylcaine Forte Spray may be used as directed in breastfeeding mothers. Phenylephrine has low oral bioavailability and it is unlikely to reach the infant in large amounts. Although oral and intravenous administration may decrease milk production, phenylephrine nasal spray is less likely to decrease lactation. Lidocaine is usually compatible with breastfeeding. No adverse effects have been reported in breastfed infants whose mothers were receiving lidocaine.
