I've been on Effexor XR since 2007 for Depression & Anxiety. I switched to the generic Venlafaxine HCL when it became available without a problem & stayed at the same dose for years. I just recently starting filling my prescription on our Military base & they gave me the brand Effexor XR again but since switching back I am experiencing anxiety, agitation, racing thought, & increased depression. Aren't the potencies the same in the brand name & the generic? What could be causing this? I've been on 150mg the entire time.
Side effects switching from Venlafaxine HCL to Effexor XR, exact same dosage?

I'm sorry, I think there is some confusion.. They are both the Extended Release capsule versions
The difference between the two, is that the XR releases the same dosage, but over a 24 hour period.
The tablets are cheaper than the capsules, so many doctors trying to save money, transferred people onto the tablets.
Sometimes people with digestive disorders absorb one form better than the other.
If you are noticing a difference, then I would ask your doctor to put you back onto the tablets that were working for you, whichever those were.
Hope that helps.
Both the generic and the brand have the same active ingredient. Though you maybe switching between the immediate release and the extended release (XR) which could explain the difference. If the symptoms continue, I would discuss with the pharmacist and the doctor.
