What are effects of oxazepam?

Depends. If you mean what is it used for, it isused to calm anxiety and agitation or to treat alcohol withdrawal. If it is working correctly you should feel calmer inside and maybe less jittery. If the dose is low and you are not sensitive, you may feel a little tired, all the rest of the feelings of Oxazepam are really side effects. You shouldn't "feel" much if properly used.
