delusional paranoia

My wife has been identified with delusional paranoia. She is scared about the world and feels very insecure. She fights with me severely, mainly on issues related to girls. She fears that I may deceive her. Is this a serious problem that requires medication? We met a psychologist and he prescribed medication (oleanz 2.5 and Feliz S 5mg), but she is not willing to take them saying it will have some adverse side effects. Can this problem be solved by counseling or other methods?

This is a serious condition and does require both medication and counseling.  You should encourage your wife to comply with the treatment recommendation, and be sure to keep her appointments for counseling.

Yes, it is a serious problem.
I have no idea what the least invasive treatment option would be.  I don't know whether this can be resolved by psychotherapy alone.
As she is experiencing psychotic symptoms it does make sense that she should be treated with anti-psychotics.  I'm not sure how well insights, etc could be accessed without them and with therapy alone, if at all.

The doctor will be better able to answer your questions.
