Suggest Substitute Medication For Cefregot

My wife and I live in Sussex, N.B. Canada and my wife has had a prescription for Cafregot for 10 yearsor more she only takes one maybe once every two months when her stomach gets upset and she gets a migraine headache. She was recently told it is no longer available in Canada, is this true or do we just need help in finding where it can be ordered legally. alngeor@nb,nb,ca
