If you are using Premarin Vaginal Cream (conjugated estrogens vaginal cream) and breastfeeding, you should know that the hormones in the cream are absorbed into the bloodstream and pass through breast milk.
Pseudoephedrine and phenylephrine can both affect pregnancy and breastfeeding. These drugs are category C drugs, which means thereâs the possibility of birth defects. Women should avoid using them during the first trimester of pregnancy and possibly throughout pregnancy. These drugs also pass into a womanâs breast milk, though phenylephrine does so in smaller amounts. That means these drugs may have side effects in a child who is breastfed by someone who takes these drugs.
