Hi all. Well my allergies have really been acting up lately.. I have been taking claritin the past few nights.. I know that benadryl will dry up your milk supply but what about claritin or other antihistamines? I am just worried that if I continue to take every day that my supply could decrease.. I appreciate any advice on this. Thanks!

Jen

The big concern with milk supply is pseudoephedrine. I don't have a copy of Hale's book with me, but I have heard that claritin (or generic equivalent) is usually OK for breastfeeding moms (very low levels get into milk) and I haven't heard of it causing low milk supply. Note, Claritin-D had pseudoephedrine in it and likely will decrease milk supply.

Nasal allergy treatments (don't know the names) are usually good too - they act locally so don't get into the blood stream as much.

Hope you feel better soon!

Thanks for the info patio.. I think i am done with claritin because it takes a long time to work and I had bad insomnia last night and I think that may have been the cause of it, since Ive heard that can be one of the side effects... I will probably be trying something homeopathic for allergies and hope that it helps!

Have you ever tried Allegra? I think Dr. Hale says it is OK too - but you would want to either check out his book or forum for that, I'm not sure. He also says that benadryl should not decrease milk supply, but that he has had some reports of it happening - so I guess it varies mother to mother.
Hope you feel better soon! Have you ever tried a netti pot?

ETA: this is from memory - so pls check it out int he book, but I think he was cautious to monitor for drowsiness in babies with benadryl too. Not sure if it was only in newborns. I have to get a copy of that book!

Hale on claritin:

"Loratadine is a long-acting antihistamine with minimal sedative properties. During 48 hours following administration, the amount of loratadine transferred via milk was 4.2 µg, which was 0.01% of the administered dose.[1] Through 48 hours, only 6.0 µg of descarboethoxyloratadine (metabolite) (7.5 µg loratadine equivalents) were excreted into breast milk, or 0.029% of the administered dose of loratadine or its active metabolite were transferred via milk to the infant. A 4 kg infant would receive only 0.46% of the loratadine dose received by the mother on a mg/kg basis (2.9 µg/kg/day). It is very unlikely this dose would present a hazard to infants. Loratadine does not transfer into the CNS of adults, so it is unlikely to induce sedation even in infants. The half-life in neonates is not known although it is likely quite long. Pediatric formulations are available.
Pregnancy Risk Category:B
Lactation Risk Category:L1
Adult Concerns: Sedation, dry mouth, fatigue, nausea, tachycardia, palpitations.
Pediatric Concerns: None reported, but observe for sedation, dry mouth, tachycardia."


on benadryl:

" There are anecdotal reports that diphenhydramine suppresses milk production. There are no data to support this theory.
Pregnancy Risk Category:B
Lactation Risk Category:L2
Adult Concerns: Sedation, drowsiness.
Pediatric Concerns: None reported, but observe for sedation. Some suggestions of reduced milk supply but these are unsubstantiated."
