We do not recommend anti-wrinkle treatments when you are breast-feeding, nor when you are pregnant. I don\’t think there will ever be full randomised controlled trials looking at the effects of anti-wrinkle treatment on breastfed infants because it would be unethical.
The Therapeutic Goods Association in Australia puts it in Category ‘C’ which means, “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”.
The first rule of medicine is “Do no harm” and applying this to your situation we cannot say for sure that there is no harm from having treatment when breastfeeding. The safest and wisest thing to do would be to finish breastfeeding and then come in to see us 🙂
