Dear Lactation Consultant,
Hi.I have to have a c-section and afterwards, due to a history of blood clots in my lungs, the doctor is putting me on Loveanox for two weeks. My question is, since the baby can not nurse due to this medication, can I pump for the first two weeks and then train him to nurse after the loveanox treatment is finished. I want more than anything to nurse my baby. Thanks for your input, nobody seems to know.Robin
Questions like this are by far the most frustrating aspect of being a lactation consultant.
The first question I have for you is who informed you so matter of factly that you can't nurse your baby while taking Lovenox, and why? I am not a doctor or a nurse, but all I have to do is pick up a copy of Dr. Thomas Hale's Medications and Mother's Milk (Tenth Edition, 2002) and look up enoxaprin (Trade name: Lovenox) and read the following:
"Enoxaparin is a low molecular weight fraction of heparin used clinically as an anticoagulant. Because it is a peptide fragment of heparin, its molecular weight is large. The size alone would largely preclude its entry into human milk at levels clinically relevant. Due to minimal oral bioavailability, any present in milk would not be orally absorbed by the infant. A simlar compound, dalteparin, has been studied and milk levels are extremely low as well."
In the book Clinical Therapy in Breastfeeding Patients (Dr. Hale, First Edition, 1999) states that
"anticoagulation therapy in breastfeeding mothers should always be approached cautiously, with close observation for abnormal bleeding".
What you have to realize is that there is no drug on the market that is not going to have this sort of disclaimer, due to concerns about liability among health care professionals. If there is even the slightest theoretical possibility that a drug might cause a medical problem, then doctors are legally required to let their patients know this. This is especially true when a patient is pregnant or lactating, and not only the mother but her infant is potentially affected. In the case of Lovenox, there have been no pediatric concerns reported via milk, and the molecular weight is too large to produce clinically relevant milk levels. In spite of this, your health care provider apparently told you point blank that you could not nurse your baby while taking this medication.
Research clearly indicates that many mothers have taken this medication without any adverse effects on their babies.I get very frustrated wtih doctors who aren't educated enough in lactation (or who don't take the time to do their research) to advise their breastfeeding patients about the actual clinical effects of taking a medication, and to discuss the options for providing the medical treatment the mother needs while still preserving the breastfeeding relationship if at all possible.
The fact is that in the vast majority of cases involving prescribing medication to nursing mothers, it is possible to continue nursing your baby without in any way endangering his health. In a risk/benefit situation, the small amount of the drug that actually transfers to the baby via breastmilk is seldom significant enough to justify advising the mother to wean (even temporarily), thereby denying the vulnerable infant with all the proven (not theoretical) benefits that human milk provides.
Advising a mother to "pump and dump" her milk while she is taking a medication is a pretty drastic step, especially when the mother in question is establishing her supply for a newborn infant. The first couple of weeks after your baby is born is considered a supply building period. The stimulation that you get during this early postpartum period, when your body is physically and hormonally "primed" to respond to this stimulation, is very important in establishing an adequate milk supply for your baby.
This is not to say that if you don't get to breastfeed your baby within a specific time frame, you are doomed to breastfeeding failure. Obviously, this isn't true because mothers of preemies who are in the hospital for extended periods of time after birth, as well as mothers who induce lactation for adopted babies are usually able to build up their supply by pumping, use of tube feeding devices, taking medications to boost their prolactin levels, etc.
By the same token, babies who aren't put to the breast for extended periods of time, (even weeks or months in some cases), are often able to be "retrained" to go on the breast, using techniques ranging from pure persistence to use of nipple shields, tube feeders, special bottles, etc. Just because these interventions exist does not justify their use unless it is absolutely medically necessary for the mother to be separated from or unable to breastfeed her infant.
I cannot give you medical advice, and would certainly not suggest that you go against your doctor's recommendations regarding the safety of taking Lovenox after your baby is born. However, I would strongly recommend getting at least a second opinion regarding this. Many health care providers who recommend weaning don't do it because they don't want their patients to breastfeed, but simply because they don't know that detailed information about the use of drugs during lactation is available.
Here is some information that you can share with your doctor that might be helpful:
Be assured that if you and your doctor decide after carefully reviewing the literature to delay putting your baby to breast for a period of time after birth, you certainly have lots of options as far as maintaining your milk supply and helping your baby latch on whenever you decide to start nursing. Make sure that you have good support from a lactation consultant after your baby is born, and she can advise you on how to maintain your supply by pumping and help you get your baby on the breast whenever you are ready. I wish you all the best.
