I was suffering from acute panic disorder with regular panic attacks. i was diagnosed with a problem acrophobia, also. I have been taking paroxetine 25 + zapiz 0.50 mg since 2004. Whenever ,I try to stop the medicine, anxiety disorder again surfaces. Doctor has advised me to continue with the same medication. I am not having any side effects till now except for early morning fatigue which lasts for about 1 to 4 hours. Kindly advise, should I continue with the same medication & can the prolonged use the same be harmful.
