your body probably just got use to the drug. talk to your doctor. maybe he can increase your dose or you can talk about other medications.
i have been on citalopram for 3 years for anxiety. it has been working up until a month ago. is this normal? . i have anxiety attacks 3 years ago i had a melt down. been taking citalopram for years and have been fine. less than a month ago i am experiencing anxiety again. not as bad as 3 years ago but have bouts of anxiety especially at work. did my body get used to the antidepressant and has become less effective? i love being on this drug no side effects and have been living a full life since taking it. could this now be a medical issue such as hormonal issues? i will be 42 in august.
