While there is no significant data to support such an association, there are some little studies indicating that moms did notice certain foods made their babies fussier than usual.

A few mothers notice minor reactions to other foods in their diet.

Some babies weep, fuss, or even nurse more often after their mom has eaten spicy or “gassy” foods (such as cabbage). These reactions differ from allergies in that they cause less-serious symptoms (no rashes or abnormal breathing) and almost always final less than twenty-four hours.

If your baby reacts negatively every time you eat a certain type of food and you discover this troubling, you can just avoid that specific food temporarily. If these symptoms continue on a daily basis and final for endless periods, they may indicate colic rather than food sensitivity.

Talk with your pediatrician about this possibility, if eliminating various foods has no effect on your child’s symptoms.

So if your little one does show an intolerance or allergy early, know that it may resolve on its own before they turn one and that continued breastfeeding may assist to protect them against allergies later on.

Loratadine Levels and Effects while Breastfeeding

Alternate Drugs to Consider

Desloratadine, Fexofenadine

Effects on Lactation and Breastmilk

Antihistamines in relatively high doses given by injection can decrease basal serum prolactin in nonlactating women and in early postpartum women.[5][6] However, suckling-induced prolactin secretion is not affected by antihistamine pretreatment of postpartum mothers.[5] Whether lower oral doses of antihistamines own the same effect on serum prolactin or whether the effects on prolactin own any consequences on breastfeeding success own not been studied.

The prolactin level in a mom with established lactation may not affect her ability to breastfeed.

One mom out of 51 mothers who took loratadine while nursing reported that she had decreased milk production after taking loratadine 10 mg daily for less than one week at 4 months postpartum.[3]

Drug Levels

After a single oral dose of 40 mg of loratadine in 6 women, average peak milk levels of 29.2 (range 20.4 to 39) mcg/L occurred at two hours after the dose.

In addition, average desloratadine peak milk levels of 16 (range 9 to 29.6) mcg/L occurred at 5.3 hours after the dose. The entire quantity excreted in milk over 48 hours was 11.7 mcg of loratadine and its metabolite. However, the dose istered was four times greater than the usual dose of the drug, so a entire 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% and of the maternal weight-adjusted dose, respectively, after the 40 mg dose.[2]

Effects in Breastfed Infants

A survey of 51 mothers who took loratadine during breastfeeding between 1999 and 2001 was conducted by a teratogen information service.

Most of the infants were over 2 months ancient and loratadine was generally taken for one week or less. Two mothers reported minor sedation in their infants, one at 3 days of age and one at 3 months of age. Both mothers were taking a dose of 10 mg daily.

Weight acquire and psychomotor development were similar to infants in a control group of breastfed infants unexposed to medications.[3] An extension of the study that compared the results of this study (plus one additional patient) to that of a control group of 88 mothers who took a drug known to be safe while breastfeeding. No differences in sedation or any other side effects (p=0.606) in the baby were found between mothers who took loratadine during breastfeeding and those of the control group.[4]

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 own a negative effect on lactation, especially in combination with a sympathomimetic agent such as pseudoephedrine. The British Society for Allergy and Clinical Immunology recommends loratadine at its lowest dose as a preferred choice if an antihistamine is required during breastfeeding.[1]
