Brief Answer: Can be tried if celexa is not effective. Detailed Answer: Hello, Thanks for posting your query. Fetzima is prescribed for a major depressive disorder. Since you have been taking Celexa for few years and you have developed tolerance for its effects it is best to switch the anti depressant medication to another suitable alternative for a better clinical effect. It is associated with more side effects but your clinician must have assessed that the benefits with this medicine will outweigh all the risks involved. You can get a second opinion regarding your line of treatment after a physical consultation with a psychotherapist. I hope this answers your query. In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out. Wishing you good health. Regards. Dr. Praveen Tayal.
