I successfully took Escitalopram for 5 years for anxiety/depression. My new GP told me to come off of it as it didn't agree long term with another drug. He put me on Sertraline 8 weeks ago and I went up to 100mg of Sertraline. Unfortunately, I feel more anxious, have intrusive thoughts, worry etc and have asked to go back to Escitalopram asap. My GP has suggested taking Sertraline for 7 days at 50mg and then next day restarting Escitalopram at 20mg. Does this sound about right? has anyone done this please?
