Yeah, a pharmacist would be the one to ask :) they'd probably know more than a dr even.

Call any pharmacist and they will know. Takes five minutes

You can pump and dump. Hun I would honestly call a good pharmacist on this. I think you wait four hours but I'm not 100% sure.

should I pump and dumb once then? Or do I just wait for 4 hours to pump and it will be good? @edomke

Yes just can't pump or feed for four hours
