I am confused about the maximum dose of pristiq. The consumer information says 50mg is the maximum therapeutic dose, yet my psychiatrist says 50mg would not be enough for me. Also, Pfizer makes 100mg tablets. Why would they make 100mg tablets while saying there is no benefit in anything over 50? I have got some initial albeit temporary benefit on 50mg but have just increased to 100mg. I'm wondering if I'm wasting my time.
