How long does it take for claritin to leave the breastmilk?… by
How long does it take for claritin to leave the breastmilk? Im going to start breastfeeding, but want to take a claritin first for my allergies. How long should I wait? (hes on formula now).
Best Answer:
There is really no need to expose baby to formula. You can continue to nurse while taking Claritin.
“The ingredients of Claritin, Claritin-D, Allegra, Allegra-D, Actifed (the decongestant pseudoephedrine plus triprolidine) and Seldane have been approved by the AAP for use by nursing moms. Loratadine (Claritin) has been studied and the amount of loratadine that passes into breastmilk is extremely low”

“Summary of Use during Lactation:
Because of its lack of sedation and low milk levels, maternal use of loratadine would not be expected to cause any adverse effects in breastfed infants. Loratadine might have a negative effect on lactation, especially in combination with a sympathomimetic agent such as pseudoephedrine.
Drug Levels:
Maternal Levels. After a single oral dose of 40 mg of loratadine in 6 women, average peak milk levels of 29.2 mcg/L (range 20.4 to 39 mcg/L) occurred at 2 hours after the dose. In addition, average desloratadine peak milk levels of 16 mcg/L (range 9 to 29.6 mcg/L) occurred at 5.3 hours after the dose. The total amount excreted in milk over 48 hours was 11.7 mcg of loratadine and its metabolite. However, the dose administered was 4 times greater than the usual dose of the drug, so a total dose of about 3 mcg would be expected with a 10 mg dose. The calculated average and maximum expected doses of loratadine plus desloratadine in milk were 0.46 and 1.1% of the maternal weight-adjusted dose, respectively, after the 40 mg dose.[1]”
