Interaction Found
Taking fluoxetine and venlafaxine together can increase serotonin levels in your body too much. This may cause confusion, muscle stiffness, rapid heartbeat, or fever. Certain stomach medicines (like cimetidine) can make venlafaxine levels higher in your blood.
What to do: Talk to your doctor or pharmacist before taking these medicines together. Tell them about all medicines and supplements you use, especially stomach medicines. Don't stop taking any medication without talking to your doctor first.
