lacidipine in pregnancy
Human pregnancy data for lacidipine are lacking. The product information recommends use only when expected maternal benefit outweighs possible fetal or newborn risks. Lacidipine is less commonly used among calcium-channel blockers; treatment should be reviewed when pregnancy is planned or confirmed and should not be stopped without medical advice.
