Venlaf Venlafaxine Desvenlafaxine Succinate
MajorDon't take Desvenlafaxine together with venlafaxine, or with any other medicine that also contains desvenlafaxine. Combining them raises the amount of desvenlafaxine in your blood. The higher level makes side effects more likely, because these side effects get worse as the dose goes up.
These medicines can affect each other in a serious way. Do not start taking them together unless your doctor has said it is OK. If you already take both, do not stop either one on your own: speak to your doctor or pharmacist soon.
