I have been treated for Altzimers for the past 4 years by my senior neurologist with 10mg of Aricept and Clonotril 0.5mg plus Mirapexin 0.18mg.Last month after tests she gave me Memantine Accord10mg morning and 10mg nightime . Now a GP changed my regime and stopped Aricept saying he did not think that I should be taking it along with Memantine. This G P does not know me. Can he do this.
