Hi, It is usual for psychiatrists to combine two anti-depressants when one medication is not effective. However, it is advisable to put in place an individualized plan of management (especially for OCD and anxiety) which includes not only medicines, but also non-pharmacological methods like behaviour therapy and relaxation techniques. Continuing Klonopin at high doses for long duartion should be avoided as it can cause dependence. Discuss with your psychiatrist about your preferences and the most bothersome symptoms which you want him to target first. This will help in setting up priorities after which problems can be dealt with accordingly.
