1137.0. "Novacaine while Nursing??" by ALFA1::PEASLEE () Fri May 03 1996 10:19

    This question really didn't fit into any of the breastfeeding notes so
    I thought I'd start a new one.
    
    I am still breastfeeding my daughter and I have a dental appointment
    today to get a tooth filled.  The doctor said that novacaine would not
    be passed into the breastmilk.   I am somewhat leary of this but I
    thought I'd ask whether or not others have heard if this is true.
    
    Thanks,
    Nancy

    That's a good question. You could call LaLeche to see if they might
    know. You might also consider, if possible, nursing right before the
    dental work. I remember being advised to take any meds that I _had_ to
    take, right after nursing, since that lessens the impact to the breast
    milk.

    I called my daughter's pediatrician - they didn't know the answer so
    they
    called Brigham and Womans Hospital and they said it was ok.  
    I'd still like other comments.
    
    Thanks,

    Since it's a local anesthetic, it should be fine.  You could try the
    maternity ward of your local hospital - there's lots of 'caine drugs,
    they should know.

    	Good point, Patty.  I'm sure many of us nursed our newborns
    	not long after receiving anaesthesia.

Novacaine is injected locally in the gum.  Within an hour or two, it has
been de-localized (ie, the freezing has worn off) and is in your bloodstream.

Most people do not notice any freezing (even partial freezing) ... ie
reduction in sensory reception elsewhere in the body, therefore, by the time
it enters the general bloodstream it is well on the way to being metabolized
and / or eliminated from the body.  Considering that it takes from 10 to
50 ml of the stuff to numb one's jaw, by the time it is diluted into the blood
stream and metabolized the concentrations are sufficiently low to not cause
anesthesia problems elsewhere.

My general take is to feed just before, and if you are concerned, skip the
next scheduled feed (and bottle feed with either previously expressed milk),
except to express potentially contaminated milk away, then resume normally
with the subsequent feeding.  4 hours should be sufficient time for any
quantity to enter the milk if it is going to in any significant quantity.

But to be honest I wouldn't worry ... I didn't hear of any problems during
the time we went through all this stuff, and my wife went to the dentist for
fillings too!

10 to 50 ml?  That's a mighty big syringe.

>10 to 50 ml?  That's a mighty big syringe.

Woops ... let's divide that by about 10!

Sorry 'bout that!
