I've been slowly weaning DS as his first birthday approaches in a few days. At this point I only nurse him when he goes to bed at 7PM, and when he wakes up between 6 and 7. My main reason for weaning is that I'd like to start taking metformin again. I was so much healthier when taking it, and without it I don't ovulate- I would like to start trying for baby #2.<br><br>
But I'm sad about the prospect of giving up those two last feedings, especially the bedtime one. My RE told me back a long time ago that I couldn't take metformin while nursing. But is this really a hard and fast rule, even if you're only nursing once a day? I don't want DS getting medication that could hurt him, but I don't want to wean unnceccsarily either.<br><br>
Anyone out there who has BFed while taking met?

An MDC "cyster," snowbunny, wrote a great article about that on our blog. It's linked in my sig. Please check it out.<br><br>
I've breastfed on Met for 20 months without any issues.

It's fine to BF on metformin. References offhand include Drugs in Pregnancy and Lactation by Briggs et al, and the Lactmed Database online.<br><a href="http://toxnet.nlm.nih.gov/cgi-bin/sis/search/f?./temp/~JLnDXd:1" target="_blank">http://toxnet.nlm.nih.gov/cgi-bin/si...temp/~JLnDXd:1</a>

I breastfed on Metformin, as well, partially to increase my milk supply. I didn't find out until much later that some thought it might be contraindicated.

thanks all! This is great. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile"><br><br>
This is typical of most info I've found online:<br><a href="http://www.storknet.com/experts/infertility/exst21.htm" target="_blank">http://www.storknet.com/experts/infertility/exst21.htm</a><br><br>
It says, "Metformin is released in breast milk. Most recommend not using Metformin while breastfeeding, although there is no specific research studies that I know of indicating that it will be of harm. Discuss your situation with your doctor/pediatrician."<br><br>
Well, that clears everything up, right? <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/orngtongue.gif" style="border:0px solid;" title="Stick Out Tongue"><br><br>
It's frustrating because so few studies have been done, and doctors are so quick to just say "just in case, you shouldn't breastfeed." Like it's no big deal.<br><br>
anyway, I'll talk to my doc and see what he says.

There's data here on 72 infants who were breastfed while Mom was on metformin. They were all OK. So while we rarely see studies done on breastfeeding Moms due to ethical issues, there is data to suggest it is safe, and I've known someone who has done it successfully. I really do think you'd be OK here.

Hale's has it listed as an L1, which is the safest category. I also recently talked with an LC who has a lot of diabetic moms who use it with no problems.
