Hello, I was given 10mg samples of Lexapro from my primary doctor to treat anxiety and since then I have been seeing a psychiatrist who prescribed the Celexa generic, Citaloproam 10mg, to start, eventually moving me up to 20mg.  I first really want to know if the two medications are interchangeable, therefore the doses, 10mgs will line up and I wont feel a drastic change from the switch. Thank you very much.~Nicole
Hi dear. I had gone through your query. Citalopram or Escitalopram are SSRI. SSRI means selective serotonin receptor inhibitor.  It increases the level of neurotransmitter like serotonin. Serotonin is one of the key neurotransmitter that involve in depression and stress. So citalopram 10 to 20 mg is ideal dose to treat anxiety and depression. Please follow advise from your treating psychiatrist. Usually it will take time to improve. Still if you have a query then feel free to ask. . Wish you a very good health. Take care.
