Your information is partially correct. Most patients of obsessive compulsive disorder require medications along with psychotherapy. The medications are prescribed for a long time, and are usually not stopped unless causing significant side effects. Obsessive Compulsive Disorder has a waxing and waning course, that usually lasts their entire lives. However, with medicines and psychotherapy, obsessions and compulsions can be very well controlled, sometimes even eliminated. Good luck.

Fear of contamination, excess hand washing, checking, anxiety and irritability are some of the features of OCD. It is advisable to go to a psychiatrist for proper assessment and diagnosis. They will be able to assess him properly and treat accordingly. Without going to a psychiatrist it is not possible to confirm the diagnosis or start any treatment. Consult a psychiatrist at the earliest. The best treatment is a combination of medication and behavioral therapy.
