methotrexate and breastfeeding

[secretarybec]

hi there
I had methotrexate single dose injection (think quite high maybe 80 mg?) about 7 weeks ago. My baby was 5 days old when I had the shot and I was told to stop bf for 3 months. I had plaenta accrete which is why I needed the drug.

I have had a lot of different opinions on this drug and bf and Im wondering if I am in fact to wait for 3 months or whether I could try to re-establish safely at this stage almost 7 weeks after the injection?

I thought i had made my peace with formula feeding but I really want to bf and it is upsetting me that I cant - if there is any concrete evidence or certainty that I will be ok to feed my baby I wuld much appreciate it

Thanks

I'm sorry, but I would probably had told you to stop for 5-7 days. Methotrexate has a short half-life of at most 15 hours. Six or at most 7 times this would have been enough to safeguard your infant.
