Erythromycin and breast feeding

[LittleOne76]

I've been prescribed erythromycin (c section infection and allergic to penicillin) by my GP and am breastfeeding my 3 week old baby at the moment. I let me GP know I was BF.

Since taking the antibiotic I've noticed that my LO has started to spit up/vomit after feeding (he didn't do this beforehand) and generally feels uncomfortable/irritable after his feeds. The change has been quite sudden and I'm thinking it could be linked to the antibiotic in my system.

I'm going back to see the Dr tomorrow to get us both checked out but wanted to see if anyone else had an experience taking this antibiotic whilst BF. It's scary seeing the LO really uncomfortable and bringing up his feeds. I know this can be quite normal but the change I've seen has been quite sudden so is a real worry.

Thanks

Oh - after feeds when he's feeling uncomfortable and irritable it's like he's trying his best top keep his food down but sounds really congested and coughs and it's like he's working harder to breathe. It's this aspect of it combined with bringing up some of his milk that makes it quite scary. I am worried that if he's lying on his back then he might choke...especially in the night.

FYI - I've stopped taking the antibiotic for the time being and will see what the Dr says tomorrow. Any info/experience with this would be appreciated.

You could try calling the BfN's drugs line:

TBH stopping taking an antibiotic can be risky so I'm not sure that's the best idea - but obviously you're in a tough situation :( Hope the visit to the GP goes ok. Incidentally, the BfN drugs line will tell you whether any drug is ok to take while BFing, even if it's noted as being not suitable.

You need to speak to your GP. I had Erythromycin when I went into premature labour to try and stop any infection so I'd have thought it was okay to take whilst breastfeeding.

Antibiotics can upset their stomachs sometimes, even if they are compatible with breastfeeding. Did your doctor know you were breastfeeding?

Summary of Use during Lactation:
Because of the low levels of erythromycin in breastmilk and safe administration directly to infants, it is acceptable in nursing mothers. The small amounts in milk are unlikely to cause adverse effects in the infant. Monitor the infant for irritability and possible effects on the gastrointestinal flora, such as diarrhea, candidiasis (thrush, diaper rash). One case report and unconfirmed epidemiologic evidence indicates that the risk of hypertrophic pyloric stenosis in infants might be increased by maternal use of erythromycin during breastfeeding.

I have been taking this medicine for 3 days now and haven't noticed any side effects on my week old baby.

Hope all works well for you x

Oh I did get thrush though - any antibiotic gives me thrush :(
