Hi, i've been on 40mg of Citalopram for 2 months now (after being on 20mg for 1.5yrs before that) but it doesn't help a lot and the Dr. wants to switch me to Sertraline. I am supposed to cross taper the medications every 2 days, 30mg Cit+25mg Sertr, 20mg Cit+50mg Sertr, 10mg Cit+75mg Sertr and then 100mg Sertraline permanently. Have anyone switched that way SSRI to SSRI and should i expect some bad SEs (i've taken Citalopram several times for the last 8 years and suffered almost no side effects) or anything serious (serotonin syndrome??)? Any info would be appreciated, especially given the fact i suffer health anxietyand every new medicine drives me crazy about my health...
