Trandate Pregnancy Warnings
-Animal studies have failed to reveal evidence of teratogenicity, although an increased incidence of fetal resorption was demonstrated in some studies at doses approximating the maximum recommended human dose. There are no controlled data in human pregnancy.
-Beta adrenergic blocking agents may cause bradycardia in the fetus and newborn infant. During the final part of pregnancy and parturition these drugs should therefore only be given after weighing the needs of the mother against the risk to the fetus.
-This drug crosses the placental barrier and has been found to bind to the eyes of fetal animals.
-Perinatal and neonatal distress (bradycardia, hypotension, respiratory depression, hypoglycemia, hypothermia) has been rarely reported. Response to supportive measures (e.g. intravenous fluids and glucose) is usually prompt.
AU TGA pregnancy category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.
US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
AU: Contraindicated during the first trimester of pregnancy.
AU (second and third trimester), UK, US: This drug should be used during pregnancy only if the benefit outweighs the risk.
AU TGA pregnancy category: C
US FDA pregnancy category: C

Trandate Breastfeeding Warnings
AU: Use is contraindicated
UK: Use is not recommended
US: Caution is recommended
Excreted into human milk: Yes
Comment:
-The effects in the nursing infant are unknown.
Because of the low levels of this drug in breastmilk, amounts ingested by the infant are small and would not be expected to cause any adverse effects in full-term breastfed infants. No special precautions are required in most infants; however, other agents may be preferred while nursing a preterm infant.
