Hi Colleen. I was have Nets in my cecum, small intestines, lymph nodes, liver and heart. I also take Escatalopram and asked my oncologist, Dr Sonbol at Mayo Clinic Phoenix the same question. He told me to continue with the Escatalopram...it will not affect the blood levels of seratonin which is what they are worried about. The Escatalopram only shows up in your urine, not your blood. I trust this man with my life, of course, so I do as he says. I have only had 3 Lanreotide injections so far and all is well with me. My blood seratonin levels decreased in my blood after the 1st injection! I feel great and will continue with the treatments until they tell me to quit.
I will have a PET scan in January to see if my tumors have shrunk. I hope this has answered your question. Good luck to you!
