As you have reasonably good control over symptoms continue it, don't stop it abruptly as it may cause relapse. Consult your treating doctor as it should tapered gradually one by one to prevent relapse.

Hi, OCD has a chronic course with relapse and remission of symptoms. You didn't mention the symptoms which u have,as some of the OC symptoms might recur after stopping the medications. But the medications should be stopped only after consulting treating psychiatrist, as those medications should be tapered slowly one by one. Also once the symptoms recur after stopping medications, you should restart the medications and continue for long duration. In some cases,the earlier medications might not work.However, there are no clear guidelines as to when exactly u can stop the medicines. My advice is to consult ur psychiatrist once and then take decision.
