In the last 3 months I have started taking Effexor XR with my Vyvanse. My Effexor is 37.5 mg once daily and my Vyvanse is 60 mg once daily. Over the last two months I have been experiencing a lot of nausea. However the last three weeks it has gotten worse and there are other things going on. I have been shaky, muscle weakness, fatigue, headaches, general nervous feeling, headaches, chills (not with fever), cloudy mind. Am I having a reaction to the two medications being mixed? What do I need to do to get off the effexor if I am?
Hello, If you are taking the 2 medications on the recommendation of the prescribing doctor then, you should check in with them for advice on how to reduce or eliminate one of them.  If you are NOT taking both together on your doctors' advice then, you probably should've been doing that, to begin with, and so it is just a matter of separating the doses out, one from the other.  You should not necessarily be taking the two medications together if they were not intended to be taken by your doctor in the first place. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
