My baby is on omeprazole and she has had purple spit up a couple of times a few hours after taking it. Never really got an answer from health professionals but I posted on here and someone replied saying it’s normal. Think omeprazole and lansoprazole are similar xx
That’s the medicine i know it’s either purple or red, my son has done that before x
You could take him down to the pharmacy and see if they can help before ringing the doctors x
