Ravi, I created an account just to answer this question. Unfortunately my account is too new so I can't PM you. There are Pilots out there who have been officially diagnosed with depression, and are taking SSRIs while remaining on duty. The UK CAA approves of 3 different medication, and that is Escitalopram, Citalopram and Sertraline. Upon declaring you have a mood disorder, you are deemed to be unfit to fly. To fix that, you will need to see your AME with a report saying you are mentally stable, followed by a visit to the CAA Psychiatrist, who will then put you forward for a Sim Check. When you pass these hurdles, you are then reissued your Class 1 Medical with Multicrew Limitations. This means you may not be allowed to fly solo on SEPs during your time off.
As I am new to PPRuNe, I am unable to post links outside the board. But if you are able to PM me or provide me with an external contact method, I can supply you with a link which contains more information.
