My son aged 18+ has been taking Paxidep CR25 for two years for anxiety, depression and OCD. After one year he stopped the medicine, the problems relapse. Dr. advised him to continue the medicine. He has also taken counseling for one year but to no avail. Now, he has concentration problems, not performing well even after hardworking, getting annoyed on small things, feeling headache, nausea, dry mouth, loss of appetite etc. Kindly guide me on my following queries:- i) How long he can take Paxidep. ii) Whether side effects of paxidep are temporary or permanent iii) whether OCD is curable or the patient has to take the medicine throughout the life.
