Is there any possible ways to prevent return of my hyperventilation symptoms after taking escitalopram 10mg for 6months?after reducing my dose to 5mg symptoms are back..i don't want to be on medication forever?

Is the hyperventilation symptoms the result of anxiety? If so, perhaps seek counseling for the anxiety from a psychologist. You can take the medicine at the higher dose to get the symptoms under control while you are being counseled. Once you are taught alternate ways of dealing with the anxiety, then lower the med dosage with the intent of stopping it if the symptoms remain resolved. Good luck!
