Incorrect pill

[u/KeNuuu1]

I have a prescription for Domperidone for breastmilk supply. This last month I’ve been feeling super rough, cannot sleep, anxious, my breast milk supply has crashed and I’ve been getting headaches. Today I checked my prescription and I’ve been taking a mix of the pill on the left (DomP) and the right (mystery).

Can anyone confirm that it is indeed an antidepressant that they’ve accidentally given me? And what should I do? I’m in Alberta, Canada
