My 10 weeks old started on Omeprazole three days ago. It’s dispensed orally via syringe. She makes the strangest movements when I give her it (a little at a time). She cry’s, arches her back and her eyes go wide. It’s almost like each one stops and she does it in that order? Cry, arch, eyes until she settles maybe 5 minutes later. It’s distressing for both her and me. Anyone else experienced this?
